Q: I am considering having a hair transplant. Does my hair need to be cut?

A: In all hair transplant procedures, we are able to transplant into areas of existing hair without it having to be cut. The question of whether hair needs to be cut in the donor area depends upon the way the donor hair is obtained (harvested).

With a Follicular Unit Hair Transplant procedure using single strip harvesting method (FUT), only the strip of hair that is removed needs to be cut. When the procedure is finished, the hair above the incision lays down over the sutured area and it become undetectable.

In Follicular Unit Extraction (FUE), particularly in sessions over 600 grafts, large areas of the donor area must be clipped short (to about 1-2mm in length) in order to obtain enough donor hair.

Q: I have been reading about hair transplantation and I have a question concerning FUT (strip-harvesting). I understand, in this method, a strip is excised from the back of the scalp, the wound then closed. I wonder, then, is not the overall surface of the scalp reduced in this procedure? After two or three procedures, especially, (or even after one large session) will not a patient’s hairline also be shifted? That is, the front hairline would move back by the amount of scalp excised, or, more likely, the “rear hairline” (which ends at the back of the neck) must certainly be “moved upward.” At least, this is how I imagine it would be. Is my logic flawed? I’ve been trying to understand this in researching the procedure, but the point still evades me.

A: The hair bearing area is much more distensible (stretchable) than the bald area and just stretches out after the procedure. As a result, the density of the hair in the donor area will decrease with each hair transplant session, but the position of the upper and lower margins of the donor area don’t move much – if at all. As a result, the major limitation of how much donor hair can be removed is the decreasing hair density, rather than a decrease in the size of the donor area.

Q: I never kept my hair really long, what length can I wear my hair after a hair transplant to hide that I had a procedure?

A: Hair transplants, whether using the strip method to harvest the donor hair or by extracting individual follicular units one-by-one directly from the scalp, will leave some scarring. If the hair is long enough so that the underlying scalp is not visible, these scars will not be seen.

The quality and density of a person’s donor hair will affect this coverage and determine how short a person may keep his hair. In some cases the back and sides can be cut to a few millimeters, in others it would need to be kept longer. Since there is no scarring in the recipient area (the front and top of the scalp where the grafts are placed) the hair in these areas may be kept at any length.

In 1995, a surgeon just entering the field of hair transplantation became aware of these natural “follicular units” and came to believe that they should be the building blocks for all hair transplants. His name was Bob Bernstein.
