Why Hair Turns Gray?đ§
Hair eventually loses its color, usually beginning in your 30s or 40s.
Though going gray is natural, many people dread it because of societyâs social notions about aging.
What gives hair its natural color?
Melanin, the brown, black or yellow, red pigment that tints skin and eyes, also dictates your hairâs hue.
Like paint-mixing, the amount and combination of melanin determines hair color.
Why does hair have color?
Scientists arenât sure. The trait may have evolved partly to help pre-humans stand out from each other, to help regulate body temperature by absorbing or reflecting sunlight.
Why does hair turn gray?
Gray hair is really hair with reduced melanin, while white hair completely lacks it.
Thatâs partly because of a  gradual decline in the number of stem cells that mature to become melanin-producing cells.
The cells may wear out, become damaged, or loose the support systems meant to keep them working.
Genes are also a factor, since they help control melanin production.
How does your hair color and type determine how you go gray?
The underlying biology is similar across hair types, even if the age of onset can vary with ethnicity.
The experience may be different by hair type and color: Grays are more noticeable for those with darker hair, while blondes can go for years unaware that grays have mixed in with their blonde strands.
The gray transition can seem slower for curly hair types, simply because it can take much longer for curly hair to look longer as it goes through many twists and turns down the length of the hair type.
Because of the corresponding change in hair texture that occurs with all graying, most hair typesâwhether curly, straight, wavy or naturalâexperience a discrepancy between the texture of gray hair and regularly pigmented hairs.
People with naturally curly hair will typically notice gray hairs curl up even tighter, while those with straight or slightly wavy hair most commonly experience breakage with their gray hairs.
Wondering what causes gray hair to feel âwiryâ?
While gray hair feels coarse and rough, the structure of the strand hasn't actually changed. When those melanin-producing cells run out of steam, the hair follicles also produce less sebum (the natural oils that hydrate hair) which makes gray hair to be drier, giving it that wiry texture.
Can anything prevent hair from graying?
For now, no.đ©
