Minoxidil can help.Minoxidil can play a role to reduce shedding of grafts and shedding of existing hair (ie. a post operative shedding) ... but does not appear to influence the chance of the grafts surviving.Here's a bit of proof:In 1987, Dr Kassimir first published that 2 of 12 individuals having hair restoration procedures demonstrated growth of the transplanted hairs without shedding. Thereafter, Dr Singh published a nice report of 40 patients showing that minoxidil didn't alter the survival rate of transplanted grafts ..... but did affect the chances that the grafts would be shed. A similar finding was then put forth by Bouhanna just a few years later.Overall, is there a role for minoxidil?Absolutely. There is a clear role for minoxidil in care before and after surgery. Minoxidil may diminish graft shedding and may reduce the post operative loss of existing hair as well ( so called post operative telogen effluvium). Whether or not one should use it, however, needs to be reviewed on a case by case basis.Oral finasteride can certainly help as well. It appears to reduce shedding and shock loss for many.REFERENCED STUDIES 1. Kassimir JJ. J Am Acad Dermatol. 1987 Mar;16(3 Pt 2):685-7.2. Bouhanna P. 1989 Jan;15(1):50-3.3.
