The progress of current treatments permits the proposal of medical or surgical therapy adapted to the degree of hair loss and baldness in each patient.
The micro-graft of follicular units is a fundamental technical advance.
This technique permits definitive hair recovery in areas of baldness in both men and women and simply and painlessly provides hair where its emergence in groups of one to three is perfectly natural.
The difference between the androgenic receptors of the occipital areas and those of other areas, explains the definitive nature of the growth of re-implanted hair.
The degree of baldness of male androgenetic alopecia can be evaluated according to the Hamilton-Norwood static classifications or be measured and tracked with greater precision by the plurifactorial dynamic classification of Dr. Bouhanna who in 1976 designed a system for the classification of male baldness which greatly simplified previous scales, with a scale of three degrees of hair loss and two variants.
The objective of this plurifactorial dynamic classification is of permitting a better adapted appreciation of the spontaneous or treated evolution of male androgenetic alopecias.
Said scale is much used by plastic surgeons, in order to evaluate their patients in hair micro-graft operations.
