Typically, white people start going gray in their mid-30s, Asians in their late 30s, and Blacks in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50.
A new study shows that stress really can give you gray hair. Researchers found that the body's fight-or-flight response plays a key role in turning hair gray. Your hair color is determined by pigment-producing cells called melanocytes.
It can be a shock to find your first gray hairs on your head, especially if you're only in your 20s. But women's expert Dr. Kirtly Parker Jones says a few gray hairs is perfectly normal, even for women in their late 20s and early 30s. However, stress, genetics and other factors can play a role.
It's most common for graying to begin in your 30s, though some people spot a few grays in their 20s. If you think you're going gray unusually early, there are a number of possible reasons why. Smoking, for one, has been linked to the early onset of gray hair.
Your hair follicles produce less color as they age, so when hair goes through its natural cycle of dying and being regenerated, it's more likely to grow in as gray beginning after age 35. Genetics can play a role in when this starts.
Despite the claims made online and by product marketers, it's not possible to reverse white hair if the cause is genetic. Once your hair follicles lose melanin, they can't produce it on their own. As melanin production slows, your hair turns gray, and then white when melanin production has completely stopped.
“Plucking a gray hair will only get you a new gray hair in its place because there is only one hair that is able to grow per follicle. Your surrounding hairs will not turn white until their own follicles' pigment cells die.”
There are no treatments that are proven to treat (or reverse) gray hair. As researchers learn more about how the graying process happens, they may develop effective medications and treatments for gray hair.
Aside from the time investment of a salon session, there's how long it takes to fully transition to gray hair, which is anywhere from six months to a year, Ferrara says.
Grey hair and genetics
The average age for grey hair varies greatly, and one of the main causes of grey hair in your 20s is genetics. The age at which a person's hair turns grey is influenced by the IRF4 gene, and one specific variant (rs12203592) is a marker for premature greying.
It's estimated that 74% of people aged 45 to 65 have at least some gray in their manes. To understand why hair may gray at the temples first, it's helpful to understand why hair turns gray to begin with.
Some women may begin going gray in their 30s or 40s. But for others, the process may begin as early as when they're 20 years old. For some women, hair can be a form of self expression. When it begins to turn gray, some women think nothing of it or even realize that they love their new silvery strands.
Does lack of sleep send my hair grey or white? Lack of sleep can have a negative effect on many aspects of the body, not only can it lead to tiredness and lack of concentration, but longer term effects such as your immune system and stress. Stress has been proven to cause grey hair as mentioned above.
Although the primary cause of premature hair graying (PHG) is considered to be genetic, certain environmental factors also play a role. Trace element deficiencies such as Vitamin B12, Vitamin D3, and calcium may also be associated with PHG.
Stress can cause hair to gray prematurely by affecting the stem cells that are responsible for regenerating hair pigment.
For grey hair coverage, we generally recommend that you aim to color slightly lighter than the natural hair color level of your client. In this case we would suggest you go for a color starting in level 6 (Dark Blonde) or 7 (Blonde).
The pigment in our hair is caused by melanin— the same pigment that is also responsible for our skin color. Gray hair is caused by a loss in melanin, whereas white hair does not have any melanin at all. As you age, your hair produces less and less melanin that leads your hair to appear gray, and then eventually white.
Gray hair is one of the universal signs of advanced age. More likely than not, at some point in your life, your hair will start to go gray. Some individuals can maintain hair color well into their older age, but most do not.
Excessive smoking and alcohol consumption can cause white or grey hair because chemicals in smoke and alcohol damage the hair follicles, causing them to lose their pigment cells prematurely.
Just like one finds grey hairs on the head upon ageing, appearance of grey hair on the eyebrows is also a sign of ageing/premature ageing. While for some, these signs start showing up in the 40's or 50's, some folks encounter the problem of grey hair on eyebrows in their 30's.
Only one hair grows per follicle. When your strand turns gray or white, the pigment cells in that follicle have already died. 1 "In other words, plucking a gray hair will only get you a new gray hair in its place," says Gillen, so any plucking is pretty much pointless. You're simply delaying the inevitable.
Vitamins B6 and B12 have also been proven to boost melanin production. Goddard says that vitamin B6, also known as pyridoxine, has been found to trigger the production of enzymes and chemical reactions that boost the metabolism of the hair proteins (keratin and melanin) in the hair follicles.
