As of now, there are no effective treatments that can reverse or prevent gray hair. New research shows that gray hair may be reversible to a small extent, but more studies are needed to look into this question further.
Pigment cells do not come back. Once hair turns grey or white, it is not ever going to turn back into brown, red, or black, or whatever your natural color was.

Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, and medications, your gray hair cannot be reversed.
If you're looking at how to increase melanin in hair, you must include in your diet, melanin rich foods and foods that are rich in vitamins. o Vitamin A – stimulates the oil-producing glands in the hair follicle and keeps the hair moisturized. Found in carrots, kale, spinach and sweet potatoes.
If the cause of greying is genetic, it is not possible to reverse the process, no matter what some marketers on the internet claim. In case of nutritional deficiencies and underlying medical conditions, you can gradually slow down or even reverse the process.
Melanin is what gives your hair (and skin) its natural color. People of African descent, Thai, and Chinese people, go grey more slowly.
The pathogenesis of graying is multifactorial such as genetic, environmental, and nutritional factors. The risk factor of premature graying is a deficiency of micronutrient serum such as zinc, copper, and selenium.
Typically, White people start going gray in their mid-30s, Asian people in their late 30s, and Black people in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50. A White person is considered to be prematurely gray if their hair turns gray by age 20.
So, Is Gen Z Aging Faster? The good news for Gen Z is that most indications of aging faster are based on lifestyle choices that can be chanted to slow the process — and Gen Z has time to reverse some negative health trends. Hold off on the Botox, fillers and retinol use until you're older.
Aging decreases the synthesis of melanin, which is the pigment that gives hair its natural color. Free radicals can accelerate this process, leading to premature gray hair. Since collagen has antioxidant properties that can combat free radicals, increasing your collagen intake may help prevent or slow down graying.
Experts emphasise that smoking and vaping are linked to premature greying, as they cause oxidative stress and reduce blood flow to hair follicles, damaging melanocytes. The toxic substances in tobacco also disrupt melanin production, contributing to greying.
In humans, thyroid hormone may reverse graying by repigmentation of terminal hair. Follicular melanocytes may be the target cell for these actions.
However, reversing your grey hair is much less likely if you're older. To reverse grey hair, you need enough melanocyte stem cells (McSCs), which produce pigment cells (melanocytes) for your hair. These stem cells stop working with age, and hair greying is thought to be irreversible when they do [3].
Regarding using baking soda for gray hair, experts endorse its potential benefits such as controlling pigmentation loss, lightening the strands, and providing texture. It can be used on coarse grey locks to make them smoother too by eliminating product buildup from oils or soaps.
A review of research suggests that proper supplementation may reverse premature graying in those who are deficient in certain nutrients, including iron, vitamin D, and vitamin B12. However, even though some supplements are specifically sold as “anti-graying,” there aren't any studies that prove they work.
It has long been thought that reversal of gray hair on a large scale is rare. However, a recent study reported that individual gray hair darkening is a common phenomenon, suggesting the possibility of large-scale reversal of gray hair.
Any deficiencies of vitamin B9, B12, biotin, or vitamin D can contribute to premature graying. One 2018 review notes various deficiency studies on vitamin D3, vitamin B12, copper, zinc, and calcium and their connection to graying hair.
While sunlight is extremely important for our body, an extreme level of sun exposure can damage your hair's melanin production. UV rays can strip off the natural shade, destroying the melanin of your hair. Your hair becomes lighter in colour.
Biotin is a key vitamin for hair growth and strength, as it stimulates the production of the hair protein keratin. Research has shown that people with prematurely gray hair tend to have lower levels of biotin, so supplementation may help counteract graying hair.
