A wrinkle-free face and a body that appears to have never birthed a child go a long way toward making gray hair more palatable to the general public — as made clear in the 2010s trend of 20 ...
A derm explains why hair can start turning gray early, specifically in your 20s. This is largely due to genetics but it can be stress, health, or other factors.
Scalp hair was reported to grow between 0.6 cm and 3.36 cm per month. The growth rate of scalp hair somewhat depends on age (hair tends to grow more slowly with age), sex, and ethnicity. [3] Thicker hair (>60 μm) grows generally faster (11.4 mm per month) than thinner (20–30 μm) hair (7.6 mm per month). [4]
The hair follicle is an organ found in mammalian skin. [1] It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions.. The hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides, and immune cells
Premature greying of hair has been observed with greater frequency among certain families, suggesting a familial predisposition for the condition. As hair pigmentation is a result of complex interaction between various genetic factors, it is thought that premature greying could be due to exhaustion of melanocyte 's capability to produce hair ...
A study links graying hair to stem cells getting stuck, unable to color new hair growth. And here's the good news: That might mean gray hair is reversible. A Study Says Gray Hair May Be Reversible
