Q: I am a 34 year old male and my dermatologist prescribed Propecia for me today. Most of my hair loss is at the hairline, but there is some loss on top as well. It’s not bad, I just want to stay ahead of it. If I get a transplant I want to get it at your clinic, but I will give the Propecia a try first. I am going to be overseas for a couple of months starting this Sunday and I was wondering about the necessity or desirability of having someone measure my hair density prior to starting the Propecia. Would you advise waiting to start the Propecia until I come back in two months and having my density examined at your clinic?

A: I would start Propecia as soon as possible. What is important for a hair transplant is the density in the donor area and this is not affected by Propecia (or minoxidil). Your donor density can be measured anytime at an evaluation prior to surgery. If you want to wait to see the effects of Propecia prior to the hair transplant, you really should wait a year; since growth, if any, can take this long. If you just want to have Propecia on board for the hair restoration procedure, or to make sure you don’t have side effects, then generally a month will do. If you would like to do a photo consult through our website to get some preliminary information about how many grafts you might need, you can do that at your leisure, but start Propecia now since the longer you wait the less effective it will be at regrowing hair.

Q: You said I was not a good candidate for a hair transplant because my donor area was too thin. Since finasteride and minoxidil can increase the thickness of the hair, could it make a hair transplant possible?

A: Unfortunately, the medication will not affect the donor area and, therefore, not make a person with low donor density a candidate for a hair transplant.

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.
