Most of people know that direct sunshine can do harm to the unprotected skin, and here is given to protection of indumentum much less attention. Meanwhile, sunlight harms hair at all not less, than skin.
Impact of the sun on hair
The person on the head has from 90 to 140 thousand hairs. Each of them is protected by the special layer consisting of tiny scales which are stuck together among themselves by keratin. This external layer adds to hair gloss, silkiness and healthy look. From April to October that is when the sun is especially active, its ultraviolet rays negatively influence protective layer of hair, the sticking together qualities of keratin weaken, scales break up that leads to the fact that hairs grow dull and break. Therefore it is very important to use in the flying the looking after cosmetics which contains ceramides and keratins, these substances anew stick together hair and return them vital forces.
It should be noted that long stay under the hot summer sun can lead to solar burn of head skin, this zone burns just as back or shoulders. The solar burn in this area leads to the fact that hair bulbs do not receive enough food and begin to drop out. Therefore rest in the warm countries if you, of course, do not pay enough attention to protection of hair and head skin, can lead to serious problems with hair.
To fair hair - special attention
Owners of fair and red hair have to be very attentive at stay in the sun. Owing to hair color at such people the pigment feomelanin which cannot provide the high level of photoprotection is developed mainly. Feomelanin quickly collapses under the influence of ultraviolet and visible sunshine, in process superoxides which have the bleaching effect are formed. As a result the cuticle of hair loses lipids that in connection with the destroyed scales of keratin leads to violation of structure of hair. They begin to behave as sponge: during bathing in the sea, salty water deeply gets into structure of hair, and they rather strongly bulk up, and after drying are reduced to the initial size, but their cuticle at the same time is strongly injured that deprives hair of opportunity to reflect light. Hair as a result lose pigmentation, become very dim and ugly, easily break and split. If you are going to tropical countries on rest, try not to dye hair before it. Any, even the sparing coloring is serious stress for hair and if to add to it influence of ultraviolet, harm can be very serious. Apply the moistening means suitable your type of hair in the flying. Shampoos, balms, masks and special oils concern them. At this time try to use less the hair dryer and other technical means for laying to reduce the level of negative impact on hair.
