Baldness (Alopecia) is most likely to happen in males than females. It may be caused by local skin conditions, systemic diseases, aging, and Baldnessgenetic factors.

Certain drugs such as prescription drugs for cancer treatment, also result in hair loss. Male-Pattern Baldness is the most hair loss type which affects men. It is rare in children and women because it depends on the androgen (male hormone) presence, such hormones levels are higher in men after puberty. Baldness runs in families. The loss of hair usually starts on the top, near the front, or on the sides of the man’s head toward the back.

Hair loss can start at any age. Some individuals lose not only some hair but also develop bald spots in the receding hairline or the back. Other people, particularly those whose hair loss starts at a young age, can go entirely bald. Female-Pattern Baldness is less likely to occur, than male-pattern baldness.

Generally, such a condition results in the hair being too thin on the crown, on the sides, or in the front. Female-Pattern Baldness rarely progresses to complete hair loss. Toxic Baldness (toxic alopecia) can be caused by a serious disease accompanied by a high fever. The condition also may be caused by using excessive doses of certain drugs, such as retinoids, vitamin A, and thallium. Many cancer medications result in baldness. Toxic Baldness can also be caused by underactive thyroid gland or pituitary one, or even by pregnancy. The hair can fall out as long as three or four months after the disease started or other conditions.

Generally, the loss of hair is temporary, and the hair grows back. Alopecia Areata is a condition, where hair is lost abruptly in a specific part, usually in the beard or scalp. In rare cases all hair on the body can be lost (called alopecia universalis). The hair usually grows back in few months.

Hair pulling  (called trichotillomania) is most likely to occur in children, but the habit can persist throughout life. Such a habit might not be noticed for prolonged period of time, making parents and doctor suggest, that the condition , such as alopecia areata results in hair loss. A biopsy (removing specimen from the skin and testing under a microscope) in some cases helps the doctor determine diagnosis.

Scarring Alopecia is the condition, in which hair loss happens at scared regions. The skin can be scarred from X-ray therapies, severe injuries, or burns.  Sometimes, Scarring Alopecia may be caused by tuberculosis, lupus, sarcoidosis, chronic fungal or bacterial infections, or lichen planus. It also may be caused by skin cancer.

Diagnosis of Baldness can be made by obtaining a biopsy. Biopsy helps define if the follicles of the hair are normal. If they are not normal, the biopsy can show possible causes. Most Baldness types are not curable. An individual , who has female or male pattern baldness, can have a hair transplantation procedure, where the follicles of hair are taken from one body area and transplanted. Some drugs, including Minoxidil, can promote growth of hair in small percentage of individuals.

Individuals with Alopecia Areata type of baldness may get injection of a Corticosteroid, administered under skin, but results might not last or be as effective. Other form of Alopecia Areata treatment consists of irritation to promote growth of hair or inducing a mild allergic reaction. Scarring Alopecia is especially hard to treat. If possible, the scarring cause is treated, but after the skin area has completely scarred, hair growth is not likely to occur.
