In winter, the hair suffers a greater dryness due to the ambient temperature since we use the heating and the hair dryer much more.

8 Keys to care for hair in winter

On the other hand, "the cold causes the capillaries to contract and less blood to reach the scalp, which is less nourished,

It should also be taken into account that sudden changes in temperature affect more fine and dry skin, while the hair is damaged by moisture and external contamination . The hair becomes dehydrated becoming brittle , and the rupture of the outer layers causes it to lose its natural shine .

Dry air with low humidity favors the hair to be charged with negative ions, causing static electricity. So it is very normal that, before or after, frizz appears .

Eight tips to protect and repair hair when it's cold

The AEDV dermatologist gives us the following keys to care for hair in winter:

    1- Use a shampoo and a more moisturizing conditioner than normal . If this is not enough, use a mask, -serum or oil to seal the hair fiber so that it does not lose its moisture. Depending on whether we have dry or oily hair, we will choose a shampoo or another.
    2- It is an ideal time to clean up ends , which is the oldest part of the hair and, therefore, the most damaged.
    3- We must dry the hair before leaving home to prevent it from losing its moisture, thus preventing hair breakage.
    4- Do not abuse the heat when we dry our hair , better put the dryer at a moderate temperature.
    5- Do not overuse the hair straightener or curling irons. One option is to use a thermal protector in these cases.
    6- You can protect your hair from the cold with the use of caps .
    7- If skiing is practiced, the hair must be protected from ultraviolet rays , since snow reflects much more ultraviolet (UV) radiation than the sea, for example. In addition, the degree of humidity in the mountain is much lower.
    8- The diet also influences the proper functioning of the scalp; If it is richer in vitamins and minerals it will help the health of our hair. In case the hair is dry, damaged or poor and with tendency to fall we can supplement our diet with specific products, such as nutricosmetics rich in amino acids, zinc and selenium.

    Does the scalp suffer more in winter?

    “In winter, pathologies such as dermatitis ( dandruff ) or psoriasis on the scalp are accentuated , since, as we have said, dryness helps make these pathologies worse and, on the other hand, we lack the beneficial effect of the sun - which It acts as an anti-inflammatory- ”, explains SeguĂ­.

    The dermatologist points out that it is not necessary to think that these pathologies are produced only by the dryness of the hair, but that there are many factors involved, such as the appearance of a fungus called Malassezia and that it is necessary to treat with a special shampoo. Hormonal factors also influence, being more frequent in men due to the influence of testosterone on the pilosebaceous follicle, and immunological (it appears more in immunosuppressed patients), and the environmental factor (worsens with temperature changes). "It is necessary to go to the dermatologist to study each particular case and to give a good treatment," said this specialist.

    In summer, hair becomes dehydrated due to severe exposure to ultraviolet rays (UVA), as well as salt from the beach or chlorine from swimming pools. It is the same effect as during winter: the hydrolipidic layer of hair is lost, affecting the cuticle.

    The contamination contains chemical elements that damage the hair, making it more fragile. This makes its appearance less healthy and has a greater tendency to fall .

    If you want to know more about hair ...

    I continued to take the opportunity to remember that the hair is formed by three layers: cuticle, cortex and medulla. And describe how each one is:
    The cuticle is the outermost part of the hair, and responsible for its shine and texture. It consists of six or eight layers of cells, protecting the underlying cortex and acting as a physical barrier against external aggressions.

    The frictional forces of brushing, dryer drying and alkaline products damage this layer, compromising its protective function.

    The crust is the next innermost layer. It contains the melanin responsible for hair color. For this reason, for the dyes to be effective they have to penetrate the cuticle and soak to the cortex. Gray hair is a normal manifestation of hair aging and is due to a reduction in melanin production.

    The medulla is the innermost part of the hair and does not perform any cosmetic function.
