How Many Hair Transplants Will I Need?

Q: How Many Hair Transplants Will I Need? — E.E., New York, N.Y.

A: The first session of a hair transplant should be designed as a stand-alone procedure with the following three goals:

  1. Establishing a permanent frame to the face by creating, or reinforcing, the frontal hairline.
  2. Providing coverage to the thinning, or bald, areas of the scalp with the hair transplant extending at least to the vertex transition point.
  3. Adding sufficient density so that the result will look natural.

Achieving all of these goals will allow the first procedure to stand on its own.

Because of this, many people feel one hair transplant is sufficient.

Reasons for Second Hair Transplant

While the first session of a hair transplant is designed to stand on its own, there are several reasons why one would want a second hair transplant, such as increasing the density in a previously transplanted area; refining the hairline created in the first transplant; focusing on increased crown coverage, when appropriate; or addressing further hair loss that’s occurred after the first transplant.

Do You Transplant Hair Evenly if I Part My Hair on the Left?

Q: For patients who intend to keep their hair parted on the left side, do you follow any rule of making the left side more dense then the right or is it distributed evenly? — M.S., Simi Valley, C.A.

A: On a first hair transplant procedure, I generally place the sites/grafts symmetrically, even if a patient combs his hair to one side. The reason is that the person may change his styling after the procedure and I like to have the first hair transplant symmetrical for maximum flexibility. An exception would be a person with limited donor reserves. In this case, weighting on the part side is appropriate in the first procedure. Once the first hair transplant grows in and the person decides how he wants to wear his hair long-term a second transplant can be weighted to accommodate this. Weighting can be done in one, or both, of two ways: 1) by placing the sites closer together on the part side or 2) by placing slightly larger follicular units on the part side.

If a person decides to comb his hair back, then forward weighting is used. For greater details on this, please see some of my publications where I address the aesthetics of hair transplantation:
