Having a very dry or very oily scalp affects our daily lives. Those with very dry scalps experience dandruff more often and those with very oily scalp experience oily hair. However, these (very dry or very greasy scalp) do not affect the result of the hair transplant in a negative way.
Only, if after hair transplant surgery has been performed, when the greasy hair gives one discomfort, because the transplanted hair will be greasy too, it might bother the patient. Otherwise, they do not have any impact on the results of the hair transplant procedure.
