GREY HAIR AT YOUNG AGE?!
grey hair, at young age? Feel like you don't have self-confidence to face the world with your hair?
This is what we want,right!Especially for girls who always want to always look beautiful
Hair colour is produced by cells known as melanocytes, which migrate into the hair bulb as the hair follicles develop in utero. The melanocytes produce pigment that is incorporated into the growing hair fibres to produce hair in a bewidering array of natural shades.
Hair colour depends on the presence and ratios of two groups of melanins; eumelanins(brown and black pigments) and pheomelanins (red and yellow pigments).
While variations in the ratio of these pigments can produce an large number of colours and tones, siblings often have strikingly similar hair colour.
Hair colour varies accordingly to body site,with eyelashes being darkest because they contain high levels of eumalanin. Scalp hair is usually lighter than pubic hair, which often has a red tinge, due to the presence of more phaeomelanin pigments. A red tinge is also common in underarm and beard hair, even in people with essentially brown hair on their scalp.
siblings always have the similar hair colour
New parents often find the first coat of their baby's hair is darker than expected. It is not until this first hair is hshed and replaced, at around eight to twelve months of age, that you get a clear indication of their hair colour
GROWTH
Human hair growth is cyclical. During the anagen phase,hair growth continuously at a rate of 1cm per month. Anagen can last three to five years on the scalp and produce hair that grows to between 36 to 60 cm in length.
At the end of the anagen phase, the follicle turns off, hair growth stops and remains off for the three months. Towards the end of this resting (telogen) phase, the hair is shed and the follicle remains empty until the anagen phase of the cycles restarts.
Pigment production also turns on and off in rhythm with the hair cycle. When pigment cells turn off at the end of one hair cycle and fail to turn back on with the one set of the next, hair become GREY.
GREYING OF HAIR AT YOUNG AGE
Greying of hair is a normal process. If your hair turns grey at a young age, it is called premature greying and needs medical attention.
15 Causes of Greying of Hair at younh age:
1) Thyroid disease - An underactive or overactive thyroid can affect melanin production in the hair and result in premature greying.
2) Vitamin B12 deficiency - Deficiency of B12 has been linked to premature greying of hair. Vitamin B12,zinc and copper are responsible for the nourishment of hair.
3) Genetic - The main reason for grey hair at early stage is genetic. The offspring is more prone to have grey hair earlier in life if its parents have the same problem.
4) Vitamin C and E - If the body suffering from lack of vitamin C and E, then hair turns grey. Their deficiency can decrease the amount of melanin producing cells and thereby cause grey hair.
5) Smoking - Smoking is also of the factors responsible for premature greying of hair. Smoking prodces free radicals in the body of the smoker and these free radicals decreases melanin.
6) Junk food - Junk food is one of the factors of greying hair at young age. Junk foods or processed food accelerate ageing by decreasing the production of melanin in hair.
7) Stress - Stress can have many effects and one of them is hair loss and premature greying. Shock, sorrow and anxiety can reduce the amount of melanin cells.
8) Faulty diet - Not having a well-balanced diet means you are lacking many nutrients. When your body doesn't get the proper supply of vitamins and minerals, it stop functioning properly.
9) Excessive use of hair iron and electric dryer - This makes the hair shaft weak. The heat produced by them can affect melanin production in hair and cause premature greying.
10) Dirty condition of the scalp - An unclean scalp due to insufficient hygiene may be another cause for premature hair greying.
11) Hair dyes - frequent use of hair dyes can damage hair.The chemicals present in then can also damage the melanin cells.
12) Washing hair with hard water - Minerals and oxidiser present in hard water cause hair fall, dry, dull, thin and frizzy hair.
13) Hormonal unbalance - Hormonal changes greatly contribute to the condition of your skin and hair. Any major hormonal changes in body in conditions such as pregnancy or thyroid disease.
14) Early menopause - women who suffer from early menopause are at risk of premature greying and may need medical attention.
15) Folic acid deficiency - folic acid is essential for many bodily processes. A deficiency of this vitamin may not only slow your hair's growth.
So, why doesn’t pigment production turn back on?
At the end of each hair cycle, some pigment-producing melanocytes become damaged and die. If the melanocyte stem cell reservoir at the top of the hair follicle can replenish the bulb, this keeps pigment production going. But when the reservoir of stem cells is exhausted, pigment production stops and the hair turns grey.
Scientists have long known that in order to prevent hair from going grey they would need to either prolong the life of the melanocytes in the hair bulb – by protecting them from injury – or expand the melanocyte stem cell reservoir in the upper or top region of the hair follicle so they continue to replace lost pigment cells.
A group of French scientists have identified a new series of
agents that protect hair follicle melanocytes from damage at the end of the hair cycle. This enables pigment production to restart as soon as the next hair cycle begins.
The agents work by mimicking the action of an enzyme called DOPAchrome tautomerase. This enzyme is the naturally occurring antioxidant in the hair bulb that protects melanocytes from oxidative damage. By duplicating the effects of DOPAchrome tautomerase, melanocyte metabolism and survival improves.
The new agents are being formulated into a product that can be applied as a spray-on serum or shampoo. But they won’t re-colour grey hair or bring back the dead cells that produce hair colour. Instead, they protect your melanocytes.
So for those who cannot find it within themselves to embrace the salt and pepper look, new options are on the horizon.
This is a video about additional information on how to treat premature greying of hair.
