LS Hair Salon from Laboratoires Sérobiologiques – have a good hair day, everyday

Published on 2008-04-21. Author : SpecialChem

The way people's hair looks and feels is important to their personal sense of well-being. However, keeping hair in good condition requires a lot of effort; without proper care, it can get dry, its color can fade, and the scalp can get irritated. To help manufacturers provide products that combat these problems, Laboratoires Sérobiologiques (LS), Cognis Care Chemicals' active ingredients business, has launched LS Hair Salon. This innovative hair care range of seven must-have active ingredients offers substantiated claims and perfectly meets consumers' demands for a holistic product experience, and so helps Cognis' customers to succeed in their markets.

The negative effects of UV radiation on the hair are well known: the texture of the hair becomes dryer and less soft, and the color fades. To prevent such alterations resulting from oxidative stress, hair care products need to contain an effective anti-oxidant which actively protects the hair fibers against photo-degradation - and this is exactly what Litchiderm™ from LS does. Thanks to its efficient free-radical scavenging effect, this polyphenol-rich lychee extract helps to reduce color fading of dyed hair and ensures hair fibers are fully protected against photo-aging. Tests carried out on human hair exposed to UVA radiation have shown that it reduces the formation of UVA-induced free radicals in a dose-dependant effect. With Litchiderm™, the hair color remains shiny and vibrant longer and hair integrity is significantly preserved. Suitable for use in daily shampoos, conditioners and sprays, this fruity and fresh active is ideal for summer hair care as well as hair color ranges.

Another common problem is frizzy hair, which results from changes in the chemical bonds within the hair fibers. Phytosleek™ from LS Hair Salon is a 3-in-1 biopolymer for natural styling of frizzy hair. Thanks to its film-forming capacity and intrinsic substantivity, this active ingredient coats the hair in a flexible layer that significantly reduces frizzing and enables full control of hair manageability. First it straightens the hair, even in humid conditions for an optimal anti-frizz action; secondly it tames unmanageable hair without any build-up effect, ensuring natural styling; and thirdly, it offers conditioning properties which make the hair brighter, softer and easier to comb. Dedicated to anti-frizz hair care ranges, Phytosleek™ can easily be incorporated into all types of hair care and styling formulations.

The third active ingredient from LS Hair Salon is Purisilk™ SPB, a botanical complex which improves hair sensorial and mechanical properties. It contains micro-proteins extracted from moringa seeds, which cationic behavior offers a substantive protection against external stress. Tested in a shampoo at two percent, Purisilk™ SPB has been demonstrated to significantly improve the resistance of the curls against pulling-induced deformation. With its strengthening action on curls retention and dynamics, Purisilk™ SPB helps maintain rejuvenated and well-defined curls and enhances their volume. This active can be used in curl-enhancing shampoos and styling products, including those for permed hair.

Active ingredients for healthy hair

Hair straightening and perms are widely used treatments which often results in an increase of scalp sensitivity and damaged hair. Phytosoothe™ from LS is a compound of phytosterols from canola and cetearyl alcohol for scalp soothing and hair beautifying. Due to their cell membrane stabilizing and leucotriene inhibiting properties (supported by literature data), phytosterols have a soothing, anti-inflammatory effect. Additionally, they have barrier function strengthening and repairing properties - a biomimetic effect owing to their structural similarity to cholesterol - and are therefore particularly suitable for the treatment of dry and irritated scalp. The anti-inflammatory effect of Phytosoothe™ has been tested in vitro. Finally, its capability to beautify the hair has been demonstrated in a clinical study on a panel of African descent, showing that it is suitable for ethnic hair care ranges. Designed to be used in all types of hair care treatments that are dedicated to sensitive scalp and damaged hair, Phytosoothe™ is easy to handle as well as energy and cost saving which is due to the lower heating requirements in production as compared to pure phytosterols.

The fifth LS Hair Salon active ingredient is Sebapure™, a sebo-regulating synergistic complex especially developed to slow down the regreasing of hair and purify the scalp. By inhibiting the enzyme responsible for the production of sebum at the scalp level, Sebapure helps control and regulate the activity of sebaceous glands. Its anti-oily effect has been demonstrated in a clinical study performed on volunteers using a shampoo containing five percent Sebapure™. This active ingredient can be used in various applications such as greasy hair care and anti-dandruff products.

Other common scalp problems include stinging, irritation, tingling and itching. In order to manage these conditions, LS offers Vegeles Propolis™, a soothing active ingredient for stressed scalp. Based on the moisturizing and anti-inflammatory properties of natural propolis, the ingredient has demonstrated in vitro its capability to reduce lipoxygenase activity, helping thereby to reduce the scalp inflammatory process such as irritations. Vegeles Propolis™ also has a long-lasting moisturizing effect, which enhances users' feeling of well-being and makes it suitable for daily use hair care products and sensitive scalp treatments.

Vitaplex™ is LS Hair Salon's synergistic complex of marine origin, which fully revitalizes the hair. It contains a combination of brown algae and red algae carrageenan extract with intrinsic natural osmo-hydro-regulating properties, that help to improve scalp vitality and enhance hair sensorial properties, which have been confirmed with an in vivo test.

Furthermore, its contents of energizing mineral salts and marine polysaccharide make it the perfect hair energy booster, suitable for specific revitalizing as well as anti-hair loss hair care ranges.

Comments Anne-Laurie Rodrigues, Strategic Marketing Manager Laboratoires Sérobiologiques: "The hair care market is very diverse, and so is our LS Hair Salon product range. Every one of the seven active ingredients has scientifically proven benefits, which will help manufacturers appeal to their target consumers."
