Hair loss, also called alopecia or baldness, is the loss of hair from part of the head or body. Typically the head is involved. The severity of hair loss can vary from a small area to the entire body.
- Hair loss in patches generally in circular patterns, dandruff, skin lesions, and scarring.
- Alopecia areata (mild-medium level) generally shows in unusual hair loss areas e.g. eyebrows, the backside of the head or above the ears where usually the male pattern baldness does not affect.
- In male-pattern hair loss, loss and thinning initiate at the temples and the crown and either thin out or falls out.
- Female-pattern hair loss occurs at the frontal and parietal.
- Hormonal changes associated with pregnancy, childbirth, discontinuing the use of birth control pills, and menopause can be the reason for temporary hair loss.
- Medical conditions that can cause hair loss include thyroid disease, alopecia areata and scalp infections such as ringworm.
- Hair loss can also occur due to medicines used in treating cancer, high blood pressure, arthritis, depression, and heart problems.
- Hair loss can be due to hair products that put pressure on the follicles by pulling the hair back tightly.
- A diet deficient in protein, iron, and other nutrients can lead to weak hair.
Medications will likely be the first course of treatment for hair loss. Over-the-counter medications generally consist of topical creams and gels that you apply directly to the scalp.
Hair Transplant Surgery
Hair transplant surgery involves moving small plugs of skin, each with a few hairs, to bald parts of the scalp. This works for people with inherited baldness since they normally lose hair on the top of the head.
In scalp reduction, a surgeon takes out a part of the scalp that lacks hair. The surgeon then closes the area with a piece of your scalp that has hair. Another choice is a flap, in which your surgeon folds scalp that has hair over a bald patch. This is a type of scalp reduction.
