Why?
Talk about protecting the hair from the sun, perhaps we should start with a brief digression on the theme "The structure of the hair, or whatever they have inside everything is happening." Those who are only interested in the practical part - what and how to use fotozaschity- recommend skip to the section "What to do? ". For the rest, tell ...
In the hair shaft differentiate three layers. Outdoor - cuticle - is composed of several layers of cells, overlapping like a tiled roof. The middle layer - the cortex - forms the bulk of the hair. And finally, an inner layer - medulla represented only in human long hair hardly plays a significant role in changing the physical or chemical properties of the hair. State rods scalp primarily depends precisely on the cuticle that protects the cortex from damage. "Tile" -kutikula by breakage is subject to harmful effects on the cortical layer and then becomes almost lifeless hair, breaks off, or, at best, sechёtsya.
Split ends - the most common injury in which a limited area fades cuticle and cortical fibers are exposed. Then, the fibers swell and are separated from each other. When combing and using a hair dryer, when mechanically damaged sand and strong gusts of wind, reinforcing hair entanglement, crosslinked fibers break the cortical layer. The underlying plot disappears, and the end of the overlying portions of the hair in the study of the light microscope looks like a brush.
The development of these changes may occur at various levels, even at a distance of 2-3 cm from the scalp, which is more common on colored hair; in rare cases even develop centers of baldness.
When good condition cuticles smooth and shiny hair - light rays reflected from the "cherepichek" evenly. Loss of natural splendor - a sign of compromising the integrity of the cuticle and unhealthy hair. Some cosmetics for hair (mostly from the range of pharmacy cosmeceuticals) are able to restore the structure of the outer layer, to cure the rod with the help of keratin hydrolyzate, mucilage or marshmallow root extract and sweet almond proteins. And then in the annotation manufacturer proudly writes "... gives a healthy shine to the hair, facilitates combing." But most mass-market funds (styling foams, gels and conditioners - conditioners) create artificial shine, disappearing after a wash.
Even dark hair (which include those much melanin) become vulnerable under a flood of ultraviolet radiation. Regardless of the color of hair from the sun discoloration occurs due to degradation of the amino acids fotozavisimoy have mans - cystine, tyrosine and tryptophan, while blond - histidine, lysine, and proline. Eumelanin in Hair defines them more resistant to the damaging effects of sunlight, and decomposition products of sulfur-containing amino acids by the action of the sun give the hair a yellowish or brownish tint.
In hair follicles redheads and fair-haired people produced mainly pheomelanin, which practically does not provide the necessary degree of photoprotection: under the influence of not only ultraviolet, visible light, but even he is destroyed and formed superoxide having bleaching properties.
Ultraviolet and sea salt, as well as the chlorine in tap water and the pool, increase lipid peroxidation protective layer of skin and hair. As a result, the formation of free radicals and lipid film suffers. Lipid peroxidation also rupture the disulfide bonds of keratin fibers cortical layer, which greatly reduces the strength of the hair.
Unlike the skin, which provides mechanisms for the protection and recovery of free radicals as well as any other environmental aggression, protected only hair keratin and melanin. Their synthesis is carried deep into the skin, and the aggressive joint influence of sunlight and seawater these protective factors is not enough.
To prevent damage to the hair must be carefully dosed sun exposure and actively defend against UV aggression. Specialized sunscreens for hair allow, on the one hand, increase the time spent in the sun, on the other hand, to reduce its adverse effects.
In such preparations should include filters / screens and a variety of rejuvenating, moisturizing ingredients.
