Hair is primarily made up of what type of cells?

Hair is primarily made up of matrix cells, which are located in the hair follicle and play a crucial role in hair growth. These cells divide and multiply to produce the keratin that forms the hair shaft, ultimately contributing to the structure and strength of hair. The hair growth process involves the transformation of these matrix cells into keratinized cells that harden to form the visible hair.

Understanding this is fundamental for an electrologist, who must have a comprehensive grasp of hair biology to effectively treat hair removal. The other types of cells mentioned, such as adipose cells, skeletal cells, and nerve cells, serve different functions in the body and are not involved in the composition or growth of hair. Adipose cells store fat, skeletal cells are involved in movement and structure of bones, and nerve cells transmit signals throughout the body. Therefore, matrix cells are the key component in hair formation, making them the correct answer to the question.
