What causes poor hair growth after a hair restoration procedure?
Although it is expected that the newly transplanted follicles will produce hair and end the patient’s concerns over their baldness and thinning, this is not always the case. There are many instances where patients experience poor growth after hair restoration. This is evident through many of the examples in our video and photo galleries where the patients presented to DR U with evidence of poor growth from their previous surgeries. Factors which cause poor growth yield include:
the selection of follicles which have already started to miniaturize
damage and trauma inflicted by surgical instruments (e.g. pulling, tucking, and inadvertent severance by the punch edge)
desiccation due to air drying
higher than ideal storage temperatures
being outside the body for too long
failure of new blood vessels to form around the hair follicles
Once follicles die, they do not regenerate. Therefore, patients who continue to show signs of baldness and thinning at over 10 months after their hair transplant will need additional surgery to fill in these areas.
