through multiple generations of women, from grandmothers and mothers - daughters and granddaughters, passed a number of useful tips to care for themselves, including - and the hair.
However, there are also candid and myths that have nothing to do with reality.How does the advice to trust, and which - not worth it?Latest research 10 popular myths about hair will help us to understand.
Now, medical researchers from New York University, experts from the American Academy of Dermatology (AAD) and a group of western parikaherov this year have taken the trouble to check the 10 popular "myths about hair."And that's what they say:
1. The first myth: from high stress hair turns gray.
Not quite right.Scientists have conducted experiments on mice to verify this assertion, and in the case of rodents evolved under strong stress hormone, in fact, to some extent influenced the appearance of gray hairs.But what about the people, doctors are not so sure of the truth of this myth, because the tendency to graying of hair in humans is also affected by genetics, disease and various other factors.
2. The second myth: if you pull out one gray hair in its place will grow two.
incorrectly.From one hair follicle can grow only one hair - though it will still be gray as the pigment cells in it have already died (hence the gray hair).So pluck gray hairs does not make sense, and even dangerous, because you can carry infection or make the scar.
3. Myth Three: If you often wear tight "tails" or braids, the hair will start to fall.
true stiff tails and braids - is harmful for hair hair, it is better not to do it often (and hair extensions - for the same reason).Although hair loss affects a lot of other factors.
4. Myth Four: If you go out in cold weather with a wet head, certainly ill.
not necessary, but possible.Hypothermia wet head leads to a narrowing of the blood vessels of the nose, which violates the power of leukocytes (white blood cells - the defenders of our body against colds and flu-causing viruses).That is, in this case sick can fall immunity caught up in combination with the virus, not just from the cold.
5. Myth Five: The head of the rinsing with cold water after washing your hair will shine.
true, but not for long.Shine hair depends on genetic factors and the integrity of the cuticle scales.Of course, the cold water from the flakes can be strongly pressed to the hair, causing the hair surface may be smoother and better reflect light.
However, for long-term effect and healthy glow is best to take care of proper hair care and nutrition, and in general - to lead a healthy lifestyle.
6. Myth Six: do not comb wet hair.
true.Wet hair is very sensitive, fragile and vulnerable, and wash them, it is best with fingertips, and even combing wet hair is generally not recommended on a regular basis - from this, they can be damaged, break, stretch, begin to split and more fall.
7. Myth Seven: the more often comb the hair, the better.
incorrectly.American dermatologists believe that just the opposite - do not comb your hair frequently, it can harm your hair, pulling them out of the follicles and weaken the individual strands, and can lead to split ends.
8. Myth Eight: pregnant women can not dye your hair.
Not really.Experts say that you should refrain from painting the hair in the first trimester of pregnancy, and then - just to avoid the colors of the old sample established on the basis of formalin.And if you decide to dye your hair at home ustloviyah best to do it with gloves and in a well-ventilated area.
9. Myth Nine: shampoo beer strengthens hair.
true, but not quite.Of course, brewer's yeast nourishes and strengthens hair, but the alcohol contained in beer they are very dry, and only left after washing the smell of this one will not please.Therefore, wishing to test the impact of beer then you should try to wash your hair something moisturizing and scented (although not a fact that will be able to repel the persistent smell).
10. Myth Ten: gray hair can be caused by smoking.
true.Ten years ago, the British Medical Journal published a study that proved - smokers turns gray in 4 times more likely to smoking.In general, smoking causes premature aging.
