Dr. Bernstein, for patients who intend to keep their hair groomed with a side part which goes from the left to the right, do you follow any rule of making the left side denser than the right by a marginal difference or is it distributed evenly?
Great question! 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.
Once the first hair restoration surgery 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 two ways; either by placing the sites closer together on the part side or by placing slightly larger follicular units on the part side – or both.
If a person decides to comb his hair back, then forward weighting is used. For greater details on this, please see some “old” publications:
