Split ends (a phenomenon also known as tricoptilosi’s) are one of the most annoying hair blemishes; this alteration of the hair shaft, frequent especially in women who wear long or medium-long hair, is characterized by the fact that on the terminal part of the hair but often also on the length, there are bifurcations that make the hairstyle appear disordered and tending frizzy with an annoying straw effect on the end of the stem.

Hair with split ends appears dehydrated, brittle and dull and often has longitudinal and transverse cracks on the length from which other split ends give rise to an aesthetic accentuation of the problem. Like other alterations affecting the hair (such as, for example, the tricoressia nodosa – formation of apparent knots on the hair – and the trichoclasia – transverse fracture of the stem interesting marrow and bark, but not the cuticle -) represent a problem of deterioration of keratin structure and hair physiology. The causes of the appearance of split ends can in fact be linked to structural deficiencies of the hair components, keratin or fundamental substance; when the keratin is in good condition, the hair is shiny and has a smooth and flat surface; the same applies to the fundamental substance, in which the keratin fibers are immersed; if it is of good quality the hair is soft and the fold holds perfectly; if this does not happen the hair appears opaque, rough, dull, the fold does not hold or is not elastic. Very often the hair tends to dry out and to produce split ends following exposure to sunlight, sea or swimming pool water and aggressive or unsuitable cosmetic treatments for the type of hair. They tend to dry out and weaken their hair, for example, even the excessive use of hair dryers and plates, as well as too frequent washing with shampoos that contain aggressive surfactants or poor quality ingredients and the running water with which we rinse them (due to the effect). of the limestone it contains); dehydrate and weaken the hair also frequent use of dyes and bleaching. Hair with double or triple tips is very delicate and breaks easily.
Every time a hairdresser makes a permanent color or even a simple shampoo, he works on the keratin of the hair a series of chemical reactions that a true professional should well know and always be able to control. Certainly the standard “tricco-cosmetic” chemistry, if wisely applied on a hair that is always perfect and of good quality, never causes unacceptable damage but unfortunately fashion today involves obligatory situations that decrease the diameter of the hair and alter the quality of keratinization with body and mass changes and the results on keratin, they are so doubtful that we can sometimes call them “tragic”.
In the cosmetic treatment of hair, aimed at the reintegration of lost proteins, only proteins and not oils or other substances that are proposed to the public due to incapacity or fashion can be used. Oil packs, even if rich in sterols (such as squalene and cholesterol), can replenish the fats that give flexibility to the hair but they certainly cannot replace the proteins lost by a keratin structure and return a condition close to that to the hair ideal; indeed, the use of unsuitable oils and balms is often the cause of further dehydration damage. If a “reconditioning” product does not contain polypeptides, the reconditioning process is not possible because (roughly speaking) the hair is made up of 80% protein and the rest almost exclusively from bound water.

Chitosan Moisturizing is formulated with substances that, being similar to the structure of the hair, restructure it, moisturize it, soften it, give a shiny appearance to the hair, make it easily moldable, close its split ends and prevent it from forming; it is also easily eliminated with a simple shampoo.
