Obviously, the main limitation of Hair transplantation is from the spread area to be thickening and the availability of transplantable hair. Less obvious, especially for younger patients, is that baldness is a dynamic phenomenon, which over the years inevitably tends to deteriorate.
The ideal patient is a person with hair loss stabilized and at least 35 years of age, whether the surgeon is often found themselves working very young patients with hair loss still in progress. It 'important that the surgeon exposes the limits of thickening honestly obtained, and avoids using all of the hair donation to recreate such a young attachment ideal but too late.
The aesthetic result of this strategy could be catastrophic years later when, with the progression of hair loss, hair fall immediately back to those transplanted (who, coming from the back, persist) at that point, no hair used in the donation, would do little to correct the error of the first hair transplant.
Hair loss is a continuous phenomenon that has a phase of very rapid fall between 20 and 35 years but does not stop even in old age.
