毛も細胞でできています。毛母細胞は毛球で分裂増殖し、新しく生まれた細胞が毛幹を押し上げるようにして毛を伸ばし、やがて角質化します。黒くみえる顆粒はメラニン色素です。
Hair is made of cells. Hair matrix cells are dividing and multiplying at the hair bulb. These new born cells push the hair shaft upward (hair growth) and become keratinized. Many black granules you can see is melanin. They are pigment produced by melanocytes and gives color to your hair.
