SOJOURN by Elan S.




by Heather Bouzan  

In case you haven’t caught on by now, the cosmetics industry isn’t just a pretty face: there are some serious chemistry brains behind your favorite volumizing mousse or age-defying foundation. But lately, we’ve been noticing beauty brands truly embracing the science-nerd side of their products instead of hiding it behind some prettily packaged gimmick or another. We, for one, are fans of this smarter side of the beauty biz – and of the industry’s recognition that its consumers know the difference between a wishful-thinking “miracle” cure and a product that actually does as it promises.More than anything, though, we love that so much of this pragmatic, results-based beauty comes with a Bostonian stamp of approval. The latest? Sojourn, a haircare line backed by the cachet of co-founder Elan Sassoon, hits shelves in early April. Available locally at Sassoon’s salon Mizu (Mandarin Oriental Hotel, 776 Boylston Street, Boston, 617.585.6498), Sojourn promotes the idea of “positive chemistry,” a concept Sassoon and his team arrived at by studying hair at its optimum natural state. Led by director of chemistry Rob Guimond, the group identified pH as a major factor in hair strength and structure; altered levels caused by environmental factors or chemical processes like hair coloring can cause locks to fade, break, or dry out. With that in mind, each Sojourn product is formulated in hair’s optimum pH range, 4.5 to 5.5.

Another factor Sojourn takes into account is one of hair’s natural building blocks: keratin. Incorporated into each product in the line, Sojourn’s Keratin Cashmere Protein works to moisturize the hair cuticle from the inside out, preventing split ends and other breakage. And if all that isn’t enough, the line is also 100% biodegradable and free of parabens, formaldehyde, sulfates, and artificial dyes and colors.

The collection itself is an ambitious one, especially for an initial launch, but we admire the way it covers all the bases. Product is divided into four color-coded subcategories – Moisture, Smooth, Volume, and Colour Preserve (their “u,” not ours) – each helmed by a targeted shampoo ($25/300 mL, $46/1 L) and conditioner ($26-$28/300 mL, $48-$52/1 L). The line’s 15 debut products range from a Sculpting Taffy ($20/150 mL), to a Leave-In Detangler ($22/250 mL), to a Monoi Oil Hair Treatment ($26/50 mL), all of which can be mixed and matched according to need and hair type.

Jumping at the chance to try Sojourn on our own heads, we snagged test samples from within each of the four groupings. Our standout favorite was the Moisture Shampoo ($25/300 mL, $46/1 L). We’d been using a drugstore brand between salon appointments, and the difference once we lathered up was clear: our hair was so soft and smooth after rinsing, we hardly felt the need for conditioner. The long-term effects of the Thermal Protection Straightener ($24/250 mL) are still to be seen, but we loved that even a healthy application didn’t leave us feeling like total greaseballs. Coupling it with with Sojourn’s Serum Smooth ($24/150 mL), we went sleek and frizz-free for a full day. And since we’re not much for gel ourselves, we had a friend slick the Wet/Dry Volume Gel ($16/150 mL) into his bedhead on a no-shower morning. He was all for its lack of stickiness, and we loved that it didn’t give off the cheesy shine that some gels can. The product scents, too, were fantastic across the board.

All said and done, the line is a debut to be commended – though we wouldn’t expect anything less from the man behind one of the city’s most tony salons. And, of course, there’s that last name of his to raise the standards even higher.

Elan Sassoon's New Haircare line, Sojourn. Sojourn Shampoo Moisture: All I have to say about this shampoo is that after applying and lathering it through my hair, it felt so moisturized I didn’t think I needed any conditioner to accompany it! The shampoo smells wonderful – with a hint of citrus. It left my hair healthy-looking and silky soft to the touch. I can definitely understand the power of the exclusive Keratin Cashmere Protein they use in this product – it does leave your hair permanently conditioned.Sojourn Conditioner Moisture: Okay…so I know I just said that I didn’t necessarily need the conditioner after the shampoo, but I used it anyways—and guess what, my hair was even MORE moisturized. I used both the shampoo and the conditioner first thing in the morning right after I woke up. My ‘bed head’ hair had tangles galore. After using this conditioner my hair felt as if I brushed them all out. On the bottle it advises you to leave the product in for two to three minutes (so it acts more like a deep conditioner). I saw a result after one minute.
Conditioner Moisture, Texture Molding Paste, Shampoo Moisture, Monoi Oil

Sojourn Monoi Oil:

In other words. Wonder oil. It’s an ultra-light yet deep conditioning treatment specially formulated for chemically treated, dry, frizzy or environmentally damaged hair. This hydrating oil absorbs almost instantly and it doesn’t leave any residue or build up. When you first apply it, you can feel it in the hair. After about 15 minutes you can’t even tell it’s there. Hair feels a lot softer after this product.

Sojourn Texture Molding Paste: This paste has a thicker texture than the taffy, so it enables you to add a little more definition to any cut or style. You can use this product to create soft and loose curls or to stand hair straight up.

Sojourn Leave-in Detangler: it’s good to use for a little extra moisture and for tangle-protection! Comb this product through with a large toothcomb, and know that it can be used alone or before applying products.

 Elan Sassoon's New Haircare line, Sojourn. Sojourn Shampoo Colour Preserve: This is formulated with a potent plant-derived UV inhibitor for maximum protection against environmental free radical damage caused by UV light. The low pH locks in color and prevents premature fading for richer, vibrant, longer lasting color and shine.A few years ago, I dyed my hair a purple–maroon color. Since I was a lifeguard at that time I had no choice but to bake in the sun pretty much every day. After all that sun, my hair turned orange and definitely did not resemble its original color. Sounds like this product would have solved that problem…Sojourn Conditioner Colour Preserve: This product provides extra UV protection for colored, chemically treated hair as well as hair that has been overexposed to the harsh effects of heat, wind and the sun. Works just like Sojourn Moisture Conditioner.
Conditioner Colour Preserve, Sculpting Taffy, Shampoo Colour Preserve, Thermal Protection Straightener

Sojourn Sculpting Taffy:
I used a small amount on my hair while it was dry (you can use it on wet hair too). It added a little texture/separation to my layers and smells marvelous — like roses! This is an all-in-one sculpting tool that gives extra hold, shine and protection to long, short, or in-between styles. Contains maracuja oil, so it fortifies hair as it styles.

Sojourn Thermal Protection Straightener: I found this is a useful product. I have used it for the past week before I straighten my hair with a flatiron. In any situation, you should apply it BEFORE applying heat on dry hair. I sprayed it on my hair from roots to ends, one section at a time for maximum protection and moisture.

Sojourn Wet/Dry Volume Gel: I took about a quarter amount of this gel and applied it at the ends to my roots. It left my hair weightless and soft. After blow-drying my hair it was like Va-Voom Volume! It works also in dry hair for a more piece-y look.So what was my favorite aspect about the entire collection besides the healthy effect it had on my hair? The scent. Floral, Herbal, Citrus…I got a surprise from ever bottle I opened. Trying out Sojourn was definitely a pleasant experience.  Elan Sassoon's New Haircare line, Sojourn.

Hair Structure


Hair is mostly made of a protein called keratin. Fingernails an the top layer of skin is also made of keratin protein. Each strand of hair consists of three layers.


1.An innermost layer or medulla.

2.The middle layer is the cortex.

3.The cortex provides strength , color, and the texture of hair.

The outermost layer is the cuticle. The cuticle is thin and colorless which protects the cortex.

The center of the hair is called the cortex. It makes up 80 percent of hair. It’s made of small fibrils that twist together to make the longer fibers stronger . The cuticle is made of of dead cells that overlap each other in several layers. The condition of the cuticle plays a part in the appearance of the hair. If the dead cells lay closely together (closed cuticles) then the hair looks shiny and healthy, however, if they lift up (open cuticles) the hair appears dull, dry, and tangles easily.

HEALTHY HAIR                                           
(Cells that lay closely together or healthy hair) 


(Lifted Hair Cells or damaged hair)

Medulla cells contain air pockets that are found inside the hair shaft which form the medullary canal. Lipids, a fat substance, is passed through to the cortex or cuticle from the medulla cells. Layers of lipids are formed to bind moisture and protein to the hair shaft. African American hair consists of 88% protein, 10-15% water, 5-10% pigments, minerals and lipids. The cortex and cuticle are formed from solid keratin fiber and the binding material is formed from amorphous keratin, which fills in the spaces inside the cortex and cuticle. The amorphous keratin holds the fibrous structure together.

Structure of the hair root


Benath the surface of the skin is the root of the hair , which is enclosed within a hair follicle. At the base of the hair follicle is the dermal papilla. The dermal papilla is fed by the bloodstream which nourishment the new hair produces. The dermal papilla is essential to hair growth because it contains receptors for androgen and male hormones . Androgens regulates hair growth.

 The Hair Growth Cycle


 Hair follicles grow in repeated cycles. A cycle can be broken down into three phases:

 Anagen – Growth Phase

Catagen – Transitional phase

Telogen – Resting Phase Each hair goes through the phases independent of the neighboring hairs.

The regeneration of hair is influenced by many factors:

  • health
  • hereditary factors
  • diet
  • hormone balance
  • age
  • physical condition
  • climate
  • chemical effects
  • sex
  • effects of disease


Your Hair is Hungry! Feed It! We all know that eating certain food is good for your body. But what about what’s good for your hair? Do you think washing and conditioning is enough? Think again. Your hair is hungry, and here’s information on how to feed it from the inside out. A healthy diet equals healthy cells, and your scalp is full of cells. It makes sense that when we eat healthy foods that help to regenerate cells, our hair will benefit. With hair growing at the rate of about ¼ to ½ inch per month, it needs plenty of iron, protein and all kinds of good nutrients to keep it healthy. Forget the supplements – you don’t need them if you eat right; let’s talk about getting what your hair needs from foods that you love. We’ll start with dark green vegetables, like spinach, green beans and broccoli. Chocked full of vitamins A and C, they help your body make sebum, that natural oil that’s found on your scalp that your hair thrives on. Dark green veggies can be eaten alone or in many recipes. (By the way, when you feel that natural oil on your scalp, massage it through to the ends of your hair before washing it out – it’s like a natural conditioner.) Let’s focus now on omega-3 fatty acids, a very good protein source. Fish oil contains plenty of omega-3, which promotes good circulation. Good circulation means more blood flow to your scalp, helping your hair stay shiny and hydrated. You can enjoy salmon and other fish, nuts, and ground flaxseed used in recipes, knowing that you’ll not only enjoy fabulous tasting foods but that you’re feeding your hair as well. Speaking of nuts, did you know they contain zinc as well? Not getting enough zinc in your diet can lead to your hair shedding, and since many of us experience thinning hair as we get older (that includes we women), we want to make sure we’re getting enough zinc in our diets.



Shampoo is a hair care product used for the removal of oils, dirt, skin particles, dandruff, environmental pollutants and other contaminant particles that gradually build up in hair. The goal is to remove the unwanted build-up without stripping out so much as to make hair unmanageable.

Shampoo, when lathered with water, is a surfactant, which, while cleaning the hair and scalp, can remove the natural oils (sebum) which lubricate the hair shaft.


Shampooing is frequently followed by conditioners which increase the ease of combing and styling.


Shampoo originally meant head massage in several North Indian languages. Both the word and the concept were introduced to Britain from colonial India. The word shampoo in English is derived from Hindi chāmpo (चाँपो /tʃãːpoː/. Its English usage in Anglo-Indian dates to 1762. In India the term chAmpo was used for head massage, usually with some form of hair oil.

The term and service was introduced in Britain by a Bengali entrepreneur Sake Dean Mahomed in 1814, when Dean, together with his Irish wife, opened a shampooing bath known as ‘Mahomed’s Indian Vapour Baths’ in Brighton, England. His baths were like Turkish baths where clients received an Indian treatment of champi (shampooing) or therapeutic massage. His service was appreciated; he received the high accolade of being appointed ‘Shampooing Surgeon’ to both George IV and William IV.

In the 1900s, the meaning of the word shifted from the sense of massage to the that of applying soap to the hair. Earlier, regular soap had been used for washing hair. However, the dull film soap left on the hair made it uncomfortable, irritating, and unhealthy looking.

During the early stages of shampoo, English hair stylists boiled shaved soap in water and added herbs to give the hair shine and fragrance. Kasey Hebert was the first known maker of shampoo, and the origin is currently attributed to him.

Originally, soap and shampoo were very similar products; both containing surfactants, a type of detergent. Modern shampoo as it is known today was first introduced in the 1930s with Drene, the first synthetic (non-soap) shampoo.

In India, the traditional hair massage is still common. Different oils and formulations with herbs may be used; these include neem, shikakai or soapnut, henna, bael, brahmi, fenugreek, buttermilk, amla, aloe, and almond in combination with some aromatic components like sandalwood, jasmine, turmeric, rose, and musk.

 How shampoo works

Shampoo cleans by stripping sebum from the hair. Sebum is an oil secreted by hair follicles that is readily absorbed by the strands of hair, and forms a protective layer. Sebum protects the protein structure of hair from damage, but this protection comes at a cost. It tends to collect dirt, styling products and scalp flakes. Surfactants strip the sebum from the hair shafts and thereby remove the dirt attached to it.

While both soaps and shampoos contain surfactants, soap bonds to oils with such affinity that it removes too much if used on hair. Shampoo uses a different class of surfactants balanced to avoid removing too much oil from the hair.

The chemical mechanisms that underlie hair cleansing are similar to that of traditional soap. Undamaged hair has a hydrophobic surface to which skin lipids such as sebum stick, but water is initially repelled. The lipids do not come off easily when the hair is rinsed with plain water. The anionic surfactants substantially reduce the interfacial surface tension and allow for the removal of the sebum from the hair shaft. The non-polar oily materials on the hair shaft are solubilised into the surfactant micelle structures of the shampoo and are removed during rinsing. There is also considerable removal through a surfactant and oil “roll up” effect.


Shampoo formulations seek to maximize the following qualities:

Many shampoos are pearlescent. This effect is achieved by addition of tiny flakes of suitable materials, eg. glycol distearate, chemically derived from stearic acid, which may have either animal or vegetable origins. Glycol distearate is a wax.

 Ingredient claims

In the USA, the Food and Drug Administration (FDA) mandates that shampoo containers accurately list ingredients. The government further regulates what shampoo manufacturers can and cannot claim as any associated benefit. Shampoo producers often use these regulations to challenge marketing claims made by competitors, helping to enforce these regulations. While the claims may be substantiated however, the testing methods and details of such claims are not as straightforward. For example, many products are purported to protect hair from damage due to ultraviolet radiation. While the ingredient responsible for this protection does block UV, it is not present in a high enough concentration to be effective. Shampoos made for treating medical conditions such as dandruff are regulated as OTC drugs  in the US marketplace. In other parts of the world such as the EU, there is a requirement for the anti-dandruff claim to be substantiated, but it is not considered to be a medical problem.

Vitamins and Amino Acids

The effectiveness of vitamins, amino acids and “pro-vitamins” to shampoo is also largely debatable. Vitamins and amino acids are the building blocks of proteins and enzymes within the body. While vitamins may be able to penetrate cells through the skin, amino acids and proteins are too large to enter a cell outside the bloodstream, and they can have no effect on dead tissue. Proteins are constructed from amino acids following an RNA blueprint inside the cell. A strand of hair is a long protein chain continually being added to at the root. The only way for an amino acid to be of any use is to be intentionally bound to other amino acids in a specific fashion by a living cell. Hair is not alive, and there is no possibility for an amino acid or protein to have any permanent effect on the health of the strand.[citation needed]

The case for vitamins is not as well understood. Some have demonstrated a moderate effectiveness in improving the health of skin,but most likely the benefit is derived from the effect of vitamins on living cells below the epidermis. Extending this benefit to hair, the vitamins and minerals could improve the health of new hair growth, but the benefit to existing hair is unsubstantiated. However, the physical properties of some vitamins (like vitamin E oil or panthenol) would have a temporary cosmetic effect on the hair shaft while not having any bioactivity.

 Specialized shampoos


Cosmetic companies have developed shampoos specifically for those who have dandruff. These contain fungicides such as ketoconazole, zinc pyrithione and selenium sulfide which reduce loose dander by killing Malassezia furfur. Coal tar and salicylate derivatives are often used as well.


Some companies use “all-natural,” “organic,” “botanical,” or “plant-derived” ingredients (such as plant extracts or oils), combining these additions with one or more typical surfactants. The effectiveness of these organic ingredients is disputed.

Alternative shampoos, sometimes marketed as SLS-free, claim to have fewer harsh chemicals – typically none from the sulfate family. They are sometimes claimed to be gentler on human hair.


Shampoo for infants and young children is formulated so that it is less irritating and usually less prone to produce a stinging or burning sensation if it were to get into the eyes. This is accomplished by one or more of the following formulation strategies:

  1. dilution, in case product comes in contact with eyes after running off the top of the head with minimal further dilution;
  2. adjusting pH to that of non-stress tears, approximately 7, which may be a higher pH than that of shampoos which are pH adjusted for skin or hair effects, and lower than that of shampoo made of soap;
  3. use of surfactants which, alone or in combination, are less irritating than those used in other shampoos;
  4. use of nonionic surfactants of the form of polyethoxylated synthetic glycolipids and/or polyethoxylated synthetic monoglycerides, which surfactants counteract the eye sting of other surfactants without producing the anesthetizing effect of alkyl polyethoxylates or alkylphenol polyethoxylates.

The distinction in 4 above does not completely surmount controversy over the use of shampoo ingredients to mitigate eye sting produced by other ingredients, or of use of the products so formulated.

The considerations in 3 and 4 frequently result in a much greater multiplicity of surfactants being used in individual baby shampoos than in other shampoos, and the detergency and/or foaming of such products may be compromised thereby. The monoanionic sulfonated surfactants and viscosity-increasing or foam stabilizing alkanolamides seen so frequently in other shampoos are much less common in the better baby shampoos. [1]


Shampoo for animals (such as for dogs or cats) should be formulated especially for them, as their skin has fewer cell layers than human skin. Cats’ skin is 2-3 cell layers thick, while dogs’ skin is 3-5 layers. Human skin, by contrast, is 10-15 cell layers thick. This is a clear example of why one should never use even something as mild as baby shampoo on a cat, dog, or other pet.

Shampoo intended for animals may contain insecticides or other medications for treatment of skin conditions or parasite infestations such as fleas or mange. These must never be used on humans. It is equally important to note that while some human shampoos may be harmful when used on animals, any haircare products that contain active ingredients/drugs (such as zinc in antidandruff shampoos) are potentially toxic when ingested by animals. Special care must be taken not to use those products on pets. Cats are at particular risk due to their instinctive method of grooming their fur with their tongues.


Solid shampoos or shampoo bars use as their surfactants soaps and/or other surfactants conveniently formulated as solids. They have the advantage of being spill-proof, and the disadvantage of being slowly applied, needing to be dissolved in use.


Stiff, non-pourable clear gels to be squeezed from a tube were once popular forms of shampoo, and can be produced by increasing a shampoo’s viscosity. This type of shampoo cannnot be spilled, but unlike a solid, it can still be lost down the drain by sliding off wet skin or hair. Soap jelly was formerly made at home by dissolving sodium soap in hot water before being used for shampooing or other purposes, to avoid the problem of slow application of solids noted above.


Shampoos in the form of pastes or creams were formerly marketed in jars or tubes. The contents were wet but not completely dissolved. They would apply faster than solids and dissolve quickly. Jar contents were prone to contamination by users and hence had to be very well preserved.

Dry shampoo

Powdered shampoos are designed to work without water. They are typically based on powders such as starch or talc, and are intended to absorb excess sebum from the hair before being brushed ou Traditional Shampoos Indonesia.

Early shampoos used in Indonesia were made from the husk and straw (merang) of rice. The husks and straws were burned into ash, and the ashes (which have alkaline properties) are mixed with water to form lather. The ashes and lather were scrubbed into the hair and rinsed out, leaving the hair clean, but very dry. Afterwards, coconut oil was applied to the hair in order to moisturize it.
