When you will start going grey depends on your genetics. Pearce said the average Caucasian will start seeing an increase in grey or white hairs around age 34, between for people with Asian heritage and 43 for people with African American heritage.
By definition, premature greying is the onset of greying before the age of 20 in Caucasians and before 30 in people with darker skin. Each can present differently - for example, a vitamin B12 deficiency may result in sandy grey hair colouring, whereas a copper deficiency can result in white unpigmented hair. Another common concern is the overnight or rapid greying of hair following a traumatic event.
There's no strong evidence to suggest stress can cause you to go grey overnight, unless you are genetically predisposed to premature greying. Pearce added this can also result from a form of alopecia areata - an autoimmune condition - where "selective breakage and shedding of pigmented hair occurs, leaving behind only unpigmented or white hairs.
As for why you shouldn't pluck out your greys, it's got nothing to do with the old wive's tale you've been taking as truth. The pace of greying is multi-factorial and genetically determined. Continually plucking will traumatise the follicle so eventually, it won't produce hair at all. Over time, excessive plucking or pulling of grey hairs - or any hairs - can lead to hair loss or thinning in places. Side note - if you've ever felt bad about grey hairs, this brilliant video will put things into perspective.
Post continues after video. Neither dying nor cutting your hair will cause any permanent damage to the hair follicles. Melanin is the pigment that gives your hair its natural color. When there is a reduction of melanin production , the hair due to factors such as ageing, stress, etc. Free radicals produced due to oxidative stress can also damage the cells in your scalp and lead to premature greying.
The hair follicle is traumatised when you pluck out a hair. But it slowly heals and a new strand of hair emerges from the follicle. But if you go on plucking on the same spot over and over again, the hair follicle will be eventually damaged. The cells around the follicle will die and the follicle will shrink altogether. So you will not get any new hair on that spot and it will lead to a bald patch on your scalp. Or resort to other means like using hair colours to cover it up.
Repeated plucking of that white hair hurts the cells in your scalp and may cause scarring or even infection. If you keep on plucking at the same spot, the hair follicles will shrink or die out.
So there will be no new hair on that spot, leading ultimately to thinning of your hair. What would you prefer, a few grey hair or less hair altogether? Plucking can alter the natural texture of your hair. The new hair that grows after plucking may be wiry and coarse. Greying is an irreversible process. So hair which have already lost their natural color cannot be reverted back to their normal coloration. But you can certainly take some steps to prevent certain forms of premature greying.
Deficiencies of certain vitamins such as vitamin B12, B6, vitamin D and E can be responsible for premature greying of your hair [ 3 ]. In the best case scenario, the gray hair that grows back in its place will be wiry—think coarser, thicker, and more noticeable than the hair you had before, says Gillen.
Gillen agrees that the best thing to do if you notice a gray hair is to ignore it—it happens to the best of us eventually—or dye it back to its original color.
If there is a gray strand you absolutely must get rid of, very carefully cut it off instead of plucking it. And of course, you can always embrace it —there's a silver lining in going gray. There is wisdom in age, after all, so consider those distinguished strands a crown of wisdom. Hana Hong headshot. By Hana Hong November 04, Save FB Tweet More.
