Saccharomyces Cerevisiae (yeast) - is a genus in the kingdom of fungi, that includes many species of yeast and means sugar mushroom (fungus) in Greek. Many members of this genus are considered very important in food production. It is known as the brewer’s yeast or baker’s yeast and used in making beer, wine, bread and kefir. Saccharomyces is also used in herbal medicine and hair care products. In herbal medicine is widely used Beta-Glucan, a bioactive carbohydrate, derived from the cell walls of Saccharomyces. Scientific studies have shown that Beta-Glucan supports immune function through its ability to stimulate macrophage activity. In Tirchology yeasts are used to nurture hair follicles. Saccharomyces is fermented in mixtures rich in a variety of minerals (zinc, magnesium, silicon, iron, copper, etc.) to deliver those minerals to the scalp.

Saccharum Officinarum (Sugar Cane) - is the main source of glycolic acid, used in topical skin care and cosmetics to battle the signs of skin aging, acne and blackheads. There are two types: alpha hydroxy acid and beta hydroxy acid. Both are used for exfoliating, or removing, cells from the upper layer of the skin. They are also used for their antiseptic properties, which is why they also appear in hair care and body care products. AHA’s can be used as water-binding agents in cosmetics, but are mostly used in modern cosmetics for their exfoliating and therapeutic properties, which help with and minimize photo damages to skin, which is a major contributing factor to ageing. 

Salvia Officinalis (Sage) - the botanic extract contains the essential oil rich in camphor, borneol and cineol. Alkaloids, flavonoids and linoleic acid glycerides are also found in sage leafs. Sage is widely known to be beneficial in hair loss treatment. It possesses disinfecting, anti-inflammatory, astringent effects and reduces sweating. In cosmetic products used for skin condition stabilizing and hair strengthening.

Salycilic Acid - It is a hydroxyacid containing phenolic group. Salicylic acid was firstly derived from the Willow bark. It possesses exfoliating and anti-inflammatory effects. Salicylic acid is soluble in fats, therefore it penetrates easily into the sebaceous gland. Cosmetic products with salicylic acid can be used on an everyday basis. It is contained in the form of esters in Birch bark and Gaulteria leafs. It possesses marked antiseptic, antifungal and keratolytic properties. Salicylic acid can be used as phytohormone. It causes temperature rise in certain organs of thermogenic plants (in particular Rafflesia Arnoldii). This effect takes place due to disruption of mitochondrial electron transport chain. Studies are now being actively performed to assess the influence of Salicylic acid on the development of non-specific response to stress-producing factors and accumulation of active forms of oxygen. softening properties. In Trichology and Cosmetology used to reduce skin irritation, itching, allergic reactions, soften skin.

Seaweed – extract has regenerating, moisturizing and nourishing properties; contains vitamins, iodine, amino acids and minerals; stimulates skin cells.

Sebacic Acid - from the Latin "sebum" (fat), organic fatty acids released from castor oil, natural "wax". In cosmetic products used to reduce sensitivity, irritation of skin as well as for hair cuticle.

Selenium - microelement, responsible for the protective functions of the skin, also has a significant impact on hair and nails.

Serenoa Repens, Serenoa Serrulata, Saw Palmetto - fruit extract has clinically confirmed anti-androgenic effects, promotes cell regeneration, has anti-inflammatory properties. The high concentration of phytosterols creates anti-androgenic effect, shows active involvement in metabolic processes of hair follicles, which determine hereditary baldness - preventing the formation of the enzyme 5-a reductase, which catalyzes the conversion of testosterone to dehydrotesterone (DHT), thus stimulating the miniaturization of the hair roots and subsequent hair loss.

Sesamum Indicum (Sesamy seed oil) - derived from seeds plant oil is pale yellow, odorless, has a sweet taste, traditionally used for dietary, cosmetic and healing purposes for thousands of years. For its highly nourishing and lubricating properties, it is popularly used for hair strengthening and to maintain scalp health.

Silicium - is a structure-forming element of connective tissues. Silicium deficiency in the body induces hair dryness, fragility, thinning and alopecia.

Silicone - trace element, plays a very important role as a structural component of connective tissue.

Silicone Dimethicone, Silicone Dimethiconol, Silicone Cyclomethicone - silicone oils, specific organic polymers based on silicone are special for their flowing properties. There are several types of silicone oils. In cosmetic products used for hair and skin conditioning by creation of a protective film on the surface of the skin and hair, which does not violate the oxygen exchange, and gives skin and hair silkness without getting them greasy and sticky.

Silk, Hydrolized Silk - the hydrolysate contains basic silk forming amino acids: aspartic acid, glutamic acid, serine, glycine, threonine, alanine, arginine, leucine, valine, methionine, phenylalanine, isoleucine, cysteine, tyrosine, lysine and proline. The complex of natural amino acids provides an optimal balance of moisturizing and protective film-forming properties, which improves hair appearance. It influences weakened and fragile hair volume, elasticity and attractive shine.

Simmondsia Chinensis, Jojoba - seed oil (which is apparently not even quite oil) and liquid wax. Its effects on hair are extremely beneficial. Quite often hair problems are associated with hair follicles being clogged by hardened sebum. Jojoba oil helps to soften and smooth out these solid formations, thus returning the natural function of the sebaceous glands and healthy follicles. Lots of problems with the hair and scalp are also associated with modern styling with various chemical products, which can permanently "settle" on theskin and hair. Jojoba oil helps to "dilutes" the remains of chemical products and bring hair back natural shine and color. The oil contains lipids, which improve the texture of the hair and moisturize them, it acts as a natural hair conditioner, which protects hair from negative influences of coloring, perms, drying, etc.

Soluble (water-soluble and fat-soluble) complex of vitamins and microelements - helps regulate adequate metabolism and metabolic processes in the scalp and exerts a beneficial influence on the hair growth, strength and appearance. The complex of vitamins and minerals helps enhance the blood circulation and the processes of cell regeneration, it increases Adenosine triphosphate supply, maintains an adequate level of protein and carbohydrate metabolism, which are required for healthy hair growth and protection against premature graying. The antioxidant properties of vitamins А, С and Е protect hair and skin from unfavorable effects of environmental factors and ultraviolet radiation, prevent hair and skin structural lipids from oxidation.

Soy, Glycine Max, Soy hydrolized protein, Soyamine - soy protein, vegetable protein, also known as vegetable placenta or dermacenta, has a balanced set of nine critical amino acids necessary for the body, and in this respect is the closest substitute of natural (animal) placenta. Soy protein (soy antioxidants and soy peptides are small particles or components of soy protein) has very strong impact on the regeneration processes; neutralizes free radicals; normalizes the production of estrogens and balances their level, especially during menstruation and menopause; affects estrogen metabolism and normalizes their level without affecting the levels of testosterone and the functioning of the thyroid-hormone; normalizes blood sugar and cholesterol levels. In cosmetic products used to regenerate skin cells, stabilize hair loss and strengthen weak hair.

Sphingolipids (ceramides) - sphingolipids were firstly derived from the brain tissue. They have got the second name, the ceramides, from the Latin word cerebrum (brain). Later it was established that ceramides form a major part of lipid layer between skin and hair horny scales. Among various ceramides, the ones containing a linoleic acid are of a special importance. These ceramides stitch together adjacent lipid layers and into one integrated structure. In case of deficiency of the ceramides or linoleic acid, the lipid layer of the stratum corneum loses its integrity and breaks up. This results in hair dryness and fragility, increased skin and hair sensitivity to adverse factors. Ceramides are one of the major lipid components of the cell membranes. It also participates in the synthesis of sphingomyelin. The biochemical cell processes such as differentiation, growth, natural ageing and death depend on their quantitative and qualitative composition. In some cases, ceramides, formed in the cell by hydrolysis of sphingomyelin, signal apoptosis (i.e. genetically controlled programmed process of cell death which is launched via specific signals). This is exactly why ceramides are the important components of anti-ageing cosmetics.

Sulfoprolamine - the active ingredient with sulfur molecules - polypeptides synthesized from corn, allows to adjust the sebum amount allocated to the skin and distributed through the hair by absorbing its surplus.

Sulfur - macroelement, essential for the activity of some enzymes.
