Explanation: 

Detailed explanation-1: -Melanin is predominantly restricted to the basal layer (or Stratum basale ) of the human epidermis, where it is found in both melanocytes (MCs), the cells that make melanin, and in nearby keratinocytes (KCs), the cells of the epidermis that accept melanin.

Detailed explanation-2: -Melanin is produced in melanocytes. These cells are located in different areas of your body, including: Your hair. The innermost layer of your skin.

Detailed explanation-3: -The stratum basale also contains melanocytes, cells that produce melanin, the pigment primarily responsible for giving skin its color. Melanin is transferred to keratinocytes in the stratum spinosum to protect cells from UV rays.

Detailed explanation-4: -Melanin is formed primarily in the melanocyte, located in the inner layers of the skin where melanin and carotene blend to produce the skin color as well as the color in the eyes and hair. Red hair is produced by pheomelanin in spherical melanosomes (melanin granules).
