A: The first paper on Follicular Unit Hair Transplantation was published by Dr. Bernstein and Rassman in 1995 in the International Journal of Aesthetic and Restorative Surgery. The title of the paper used the abbreviated name Follicular Transplantation. The longer name “Follicular Unit Transplantation” was formalized by Bernstein et. al. in the paper “Standardizing the classification and description of follicular unit transplantation and mini-micrografting techniques.” This paper appeared in Dermatologic Surgery in 1998.

Follicular Unit Extraction derived its name from Rassman and Bernstein’s publication “Follicular Unit Extraction: Minimally invasive surgery for hair transplantation” that appeared in Dermatologic Surgery in 2002.

A: It depends upon the person’s age, how bald he is likely to become, and the donor supply.

As a general rule, the crown should not be transplanted in a younger person (under 30) as the extent of his balding is hard to predict and crown thinning at this age often suggests that the person will become at least a Norwood 6.

If a person has enough donor hair (i.e. good donor density) and scalp laxity, so that coverage of the entire bald area can be accomplished if the patient becomes a Norwood class 6 (and it is unlikely that he will become a Class 7), then transplanting the crown before the front is reasonable.

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.
