Excessive Hair Growth

Question:

Is hirsutism that was caused by the overuse (for about six years before and during puberty) of topical cortisones and topical steroids for eczema permanent?

Answer:

Hirsutism is the excessive growth of hair on the face and other areas of the body where hair does not usually grow. In females, the excess hair often occurs on the face, chest and around the nipples. The hair is usually dark and coarse.

A tendency towards hirsutism is often inherited ("familial hirsutism").

The underlying cause of hirsutism is usually an excess of androgen, a male hormone. The excess may result from conditions that affect the level of androgens in the body. Examples include:

• Polycystic ovary syndrome

• Obesity

• Enlargement of the adrenal glands

• An under active thyroid gland (hypothyroidism)

• Excessive growth hormone

• Certain rare tumors

Some medications, such as high-dose oral steroids, can also induce hirsutism.

It is less likely that steroids applied to the skin would result in hirsutism, unless they were applied over large areas of the body for long periods of time.

Another condition of excessive hair growth, called "hypertrichosis," more often occurs where steroids have been applied for long periods of time. In this condition, the hairs are fine, light, soft, and short - like peach fuzz. The hair growth usually stops (eventually) after the medication is no longer applied. In some cases, the problem can persist for a long time.

Because there are many underlying causes of excessive hair growth, it is important to see your doctor. Your doctor can evaluate and treat any underlying medical problem that may be contributing to the condition.

Your doctor can also discuss options for hair removal, which include laser treatment and electrolysis.
