Moles are common skin growths that are usually brown or black in color. They are caused by an overgrowth of pigment-producing cells called melanocytes. Hairs often grow out of moles, and they may be thicker and darker than the hair on the rest of the body. There are a few reasons why hairs grow out of moles faster than they do on other parts of the body.
One reason is that moles are located in areas of the body that are exposed to a lot of sun. Sun exposure can damage the DNA in the skin cells, which can lead to the development of moles. The damaged skin cells can also produce more melanin, which can make the moles darker and thicker. The increased sun exposure can also cause the hair follicles in the moles to become more active, which can lead to faster hair growth.
