In fact, research published in showed a connection between hair abnormalities and thyroid dysfunction. White hair is also common in alopecia areata , an autoimmune skin condition that causes hair loss on the scalp, face, and other parts of the body. When the hair grows back, it tends to be white due to melanin deficiency. One study from New York University, reported in Nature Medicine , finds that the cells responsible for hair color can be depleted when the body is under stress.
Other studies indicate that while stress may play a part, it is only a small part of a bigger picture where disease and other factors contribute. A study in the Journal of the American Academy of Dermatology also demonstrated that smoking is linked to premature white hair in young men.
Chemical hair dyes and hair products, even shampoos, can contribute to premature hair graying. Many of these products contain harmful ingredients that decrease melanin. Hydrogen peroxide, which is in many hair dyes, is one such harmful chemical. Excessive use of products that beach hair will also eventually cause it to turn white. Image: Joesph Chan via Unsplash. There are a number of ways to fix or reverse this process, but ultimately your body will decide what it wants to do.
Eating more antioxidants for one is key. This can include, fresh fruits, vegetables, green tea, olive oil, and fish. There are also many natural remedies like curry leaves. The medicinal use of curry leaves goes back centuries. When combined with hair oil and applied to the scalp, curry leaves can slow premature graying. Cotsarelis insists that is just not the case. Part of the reason is because you stimulate the [plucked] hairs to go into a growing stage.
Most of the time, only about 90 percent of the follicles on your head are growing at any one time, says Cotsarelis, but when you rip out the hair, it makes those follicles all grow new strands simultaneously, so it looks thicker.
As you age, you start to lose hair volume and the texture can change. That, or color your hair. A few grays at 25 are nothing to have a complete nervous breakdown over, but I did want to know why it was happening, regardless. Kingsley explained that gray hair occurs when the hair follicle stops producing melanocytes—pigment cells that give hair its color.
When this happens is mostly down to genetics, however there are a number of factors that can contribute to graying. Among those, Kingsley names vitamin B deficiencies, diabetes, pernicious anaemia, and thyroid disorders.
And for those of you who have noticed a gray and wondered why it grew back in a different texture than the rest of your hair, turns out you're not imagining it. But your hair may feel more coarse because, as we age, sebum production from the sebaceous glands on our scalp decreases. Want to cover it up with hair dye? The typical amount of time people go between touching-up color, according to Hazan, is weeks, but if you don't have a lot you can wait months.
I wanted to know what I could do to cover my grays, given my clear distaste for their presence. Sarah Spratt comforted me with the notion that you can do a number of things. You can go in and just spot treat the grays with color, or you can create a visual distraction. You don't have to start dyeing your whole head of hair, and going grey doesn't have to be the end of the world. You could even just own it and look great that way.
