24 Year Old Male with Receding Hairline and No Change in His Hair Loss over the past Year on Haircheck Test

I have performed a HAIRCHECK test on this now 24 year old male with a receding hairline last year and then again today. His hair has shown stability and very little loss as the drug finasteride seems to be helping him hold onto his hair.  I told him to return in a year for another HAIRCHECK test and to see if his corner frontal recession bothers him. A hair transplant is a viable option.
