What Causes Pubic Hair Loss & How is it Treated?

Hormones

Hormones are the chemical messengers produced in the body and they affect the activity throughout the body which includes growth, metabolism, fertility, immunity, and behavior.

During puberty, there is an increase in hormones that trigger hair growth.(1)  Dehydroepiandrosterone (DHEA) is produced in the adrenal gland that affects pubic hair.

If the production of this hormone is lowered, pubic hair loss can be a symptom. Aging lowers hormone production. Also, Addison’s disease affects adrenal glands inhibiting hormone production.

Treatment: Both men and women can be affected by DHEA deficiency and can be treated with DHEA supplements.

Alopecia Areata

Alopecia areata is an autoimmune disease in which the hair follicles are attacked by the body’s defense mechanism. This causes hair loss.

It can affect the hair of any part of the body.

Treatment: There is no cure for alopecia areata. The doctor only tries to block the immune system attack and stimulate the new hair follicles with the treatment such as topical corticosteroids, injectable corticosteroids, oral corticosteroids, topical minoxidil, immunotherapy, and immunomodulators.

Atrophic Vaginitis

Atrophic vaginitis is a condition in which there are changes in the tissue of the vulva and the vagina. It occurs due to a decrease in estrogen level and is most commonly seen in women experiencing menopause.

Along with sparse pubic hair, other possible symptoms are patchy redness of the skin, small tears in the vulva, labial fusion, and shrinking of vaginal tissue.

Treatment: Estrogen replacement therapy is a primary treatment for this condition. Those who want to avoid this therapy can manage the symptoms with vaginal lubricants, lotions, and moisturizers.

Aging

As the body ages, it undergoes a number of changes. The changes begin at the cellular level decreasing the rate of cell growth. This causes physical changes such as wrinkling, loss of height, and loss of pubic hair.

In the females as menopause arrives there is a change in the hormone which can cause pubic hair loss.

Medications

There are a few medications that can cause hair loss. It can be anywhere including the scalp and pubic region. Hair loss is due to their side effects.

Medicines prescribed for depression or bipolar disorders are known for causing hair loss that can also include hair in the pubic region.(2)

Chemotherapy medicines are also known to induce hair loss including pubic hair loss.

Birth control pills, gout medications, beta-blockers, and blood thinner can also disrupt the normal hair growth cycle and cause hair loss.

Treatment: This type of hair loss is temporary and reverses as soon as the medications are stopped or the treatment is completed.

Radiation Therapy

Radiation therapy is another cancer treatment that can lead to hair loss. The hair loss is mostly in a place where the radiation is given. If the radiation is given in the pelvic region, the hair loss occurs in the pubic area.

If the radiation frequency is low the hair loss is temporary and if the radiation doses are high the hair loss can be permanent.

Apart from hair loss, other side effects can be fatigue and skin changes.

Treatment: Mostly the hair grows back after the therapy is stopped. Otherwise, there is no cure for this type of hair loss. Counselling and group therapy session can help people emotionally to cope with the effects of hair loss.

Due to aging, pubic hair thins out naturally. But if excessive hair fall is noticed, it could signal a serious underlying condition. A doctor should be consulted in such a case so that the condition is diagnosed and the necessary treatment is started.
