Hair Disorders and Hair Loss Procedures

Most people have as many as 100,000 hairs on their head, shedding 50 to 100 hairs daily. Each hair on your head grows for about 2 to 6 years, with scalp hair growing about one-half inch a month. Approximately 90 percent of the hair on your scalp grows continually, with about 10 percent of your hair in a resting phase lasting 2 to 3 months. As you age, the rate of hair growth slows.

Causes of hair loss may include:
  • Aging
  • Changes in hormones
  • Illness
  • Family history of baldness
  • Burns and trauma
  • Ringworm
  • Vitamin deficiencies

Northwestern Medicine specialists offer advanced treatment for hair loss by performing surgical and non-surgical hair replacement procedures, including:

  • Hair transplant surgery: In this procedure, the surgeon removes patches of skin containing hair to balding or thinning areas.
  • Tissue expansion: Tissue expansion involves hair-bearing skin being stretched to cover balding areas.
  • Flap surgery: In this surgery, a portion of balding skin is removed and replaced with a flap of hair-bearing skin.
  • Scalp reduction: Sections of bald scalp are removed and the hair-bearing parts of the scalp are pulled together to fill in the area.
  • Non-surgical options: Non-surgical treatment options include finasteride, a pill for treating baldness that blocks the enzyme responsible for hair loss, and over-the-counter topical solutions such as minoxidil (Rogaine®).
