6 things you need to know about gray hair

  1. . Your lifestyle makes a difference.
    Smoking, for example, stresses your skin and hair. “Low vitamin B12 levels are notorious for causing loss of hair pigment  Try eating foods such as liver and carrots, recommends. Foods packed with certain vitamins, nutrients and antioxidants may help protect cells against toxins and help prevent heart disease, cancer, and other ailments (and perhaps grey hair!).
  2. Hair and its colour are separate things. 

    Hair stem cells make hair, and pigment-forming stem cells make pigment. Typically they work together, but either can wear out, sometimes prematurely. Researchers are trying to figure out if a medicine, or something you could put in your scalp, could slow the greying process. (Hair dye simply coats your hair in colour but doesn’t alter its structure.)
  3. Your hair basically bleaches itself.

    You may be familiar with hydrogen peroxide as a way to go blonde, but it’s also the way we go grey. According to a 2009 study published by the Federation of American Societies for Experimental Biology, hydrogen peroxide naturally occurs in our hair follicles, and as we get older, it builds up. This build-up blocks the production of melanin, a.k.a. our hair’s pigment.
  4. Your hair doesn’t turn grey – it grows that way.

    A single hair grows for one to three years, then you shed it – and grow a new one. As you age, your new hairs are more likely to be white. “Every time the hair regenerates, you have to re-form these pigment-forming cells, and they wear out,”
  5. Grey hair isn’t more coarse than coloured hair.
    Grey hair is actually finer than coloured hair, but it may seem drier because our scalps produce less oil as we get older. Another reason it could seem more rough? “Your hair may also ‘feel’ coarser if you pull out your first few grey hairs “This is because constant pulling-out of hair can distort your follicles, resulting in more crinkly hair.”
  6. Grey hair can be resistant to colour.

    If you opt to colour your hair, you may find that it’s more stubborn about taking colour than before you started going grey. “Some grey can be resistant to hair colour,” an experts said “If this is true for you, consider dropping down a colour level or using something darker on your roots to deliver even more coverage.”
