The hair cosmetics have three important functions: a detergent (shampoo), a eutrophic (lotions capillaries), a cosmetic (gel, hairspray, tunturi, dyes, etc...)
The coat (hair) is a natural protein fiber, consisting of cysteine, glycine, arginine, histidine, etc.. These constituent amino acids form two different types of proteins, and macroproteine \u200b\u200bmicroproteins. The
macroproteine \u200b\u200b have a high molecular weight, and to form the cortex of the hair, ie the second layer of coating. The property is in alpha helix and is stabilized by weak bonds such as hydrogen, ionic and VDW forces, which as a whole, however, give resistance to changes. The hair is so flexible. The macroproteine \u200b\u200bcontain little cysteine. The
microproteins have rather low molecular weight, and form the hair cuticle, which is the outer coating. Cysteine-rich, have a band structure very rigid, consisting of disulfide bonds, which confer high protection against external agents.
The hair lotions come in and DANDRUFF REVITALIZING . The anti-dandruff
have antifungal and antibacterial properties. The active ingredients used are ketoconazole , Climbazole , zincopiritione , quaternary ammonium bases , sulfur and tar , along with mild anionic and amphoteric surfactants in ethanol solvent.
All these substances are essential to restore the health of the scalp, encourage cell renewal and exfoliation of the stratum corneum.
revitalizing I have mainly eutrophic action on the hair bulb matrix. They are divided into rubefacient, vitamins, nutrients and biostimoline.
I rubefacient draw blood to the papilla of the hair and promote cell renewal and growth. Contain China and Minoxidil. The vitamin
contain vitamin A, B, B5, cell stimulation with action, respectively, for help against seborrhea and growth.
contain provitamin A nutrients, amino acids, sugars, and placenta. Those
Biostimoline to enhance the activity of hair matrix cells, and are often flavored with nettles, rosemary and sage.
