This melanin pigment is made by special cells called melanocytes. These cells live at the bottom of each strand of hair. When these cells make a lot of melanin, your hair turns brown or black. If these cells don’t make much melanin, your hair turns blonde.
Also, do people notice blonde leg hair?
Yes, it’s very noticeable, especially the lower part of the leg. Hair on thighs is usually less noticeable, and sometimes you can even pass without shaving thighs at all, but hair on knees bellow is very easy to spot, especially if the girl has dark hair, which would make her leg hairs darker too.
Keeping this in view, why is the hair on my legs turning black?
When the follicle or clogged pore is exposed after shaving, and air reaches the oil inside, it oxidizes and turns dark.
