  • Baldness or the loss of hair.
  • Baldness; absence of hair from skin areas where it is normally present.
  • Did you know that you lose up to 100 hairs from your scalp every day? that's normal, and in most people, those hairs grow back. But many men -- and some women -- lose hair as they grow older. You can also lose your hair if you have certain diseases, such as thyroid problems, diabetes or lupus. If you take certain medicines or have chemotherapy for cancer, you may also lose your hair. Other causes are stress, a low protein diet, a family history or poor nutrition. Treatment for hair loss depends on the cause. In some cases, treating the underlying cause will correct the problem. Other treatments include medicines and hair restoration.
  • Hair loss usually from the scalp. It may result in bald spots or spread to the entire scalp or the entire epidermis. It may be androgenetic or caused by chemotherapeutic agents, compulsive hair pulling, autoimmune disorders or congenital conditions.
  • The lack or loss of hair from areas of the body where hair is usually found. Alopecia can be a side effect of some cancer treatments.
