Q: What is the problem with transplanting the crown too early? — P.L., Newark, NJ

A: If a person’s hair loss continues – which is almost always the case – the crown will expand and leave the transplanted area isolated, i.e. looking like a pony-tail. The surgeon can perform additional hair transplant procedures to re-connect the transplanted area to the fringe, but, as one can see from the photo below, this is a large area that can require a lot of hair. It is often impossible to determine when a person is young if the donor supply will be adequate. If there is not enough donor hair, then the island of hair may remain isolated. Most importantly, it uses up a lot of hair that might be better transplanted to the front and top of the scalp – areas that are far more important cosmetically.

Patient who visited us who had an early crown transplant

The front and top of the scalp are more important to one’s appearance than the crown, and these areas should be the first priority when planning hair restoration surgery.

As an exception, if a person has a family history of baldness limited to the crown, even at an advanced age, and the person in question is following this pattern, then earlier treatment of the crown may be considered.

Lastly, if you do treat the crown in a younger person, or one with whom the extent of hair loss is uncertain, the crown should be transplanted with light coverage only. That way a limited amount of hair will be used up in this area and there will be enough left over for the more cosmetically significant top and front of the scalp.

Q: I’ve read about some recent advances in hair cloning techniques with ACell. How does this work? — C.A., Stamford, CT

A: We, and several other groups, are engaged in studies using ACell MatriStem, a porcine extracellular matrix (ECM), to induce hair follicles to multiply in the patient’s own scalp (in vivo). This process differs from what people normally think of when speaking about cloning, namely producing populations of genetically identical cells, organs, or even individuals, in a test tube (in vitro).

In the current studies, a part of a hair follicle is implanted into the scalp in an extracellular matrix (ACell MatriStem), with the goal of inducing a complete follicle to form.

The concept is that if a small enough part of the donor follicle is removed, it will completely regenerate. Then, ACell MatriStem will induce the new hair fragment, implanted into the recipient site on the top of the scalp, to produce a new follicle –- thus we get two hairs from one. In one model being tested, hair is literally plucked from the scalp carrying with it enough genetic tissue to grow a new hair.
