Thank you for posting this question. A hair transplant surgery does literally nothing to stop the inevitable progression of hair loss. Hair loss is a lot like dental decay....in 3 important areas:1) both are incurable2) both are progressive in nature3) both are with you for lifeSo, the most likely reason for your thinning hair is the same reason that you sought out a hair transplant in the first place: male pattern hair loss. You should be treating the hair loss aggressively with things like finasteride, LLLT, PRP procedures, etc. If you don't then you'll end up having far more hair transplant procedures in your life than you had planned. Not treating hair loss but getting hair transplant surgery is a bit like refusing to brush your teeth and just going to the dentist to get new porcelain ones surgically implanted as your own teeth rot out. So, my advice is to step up your game in your hair loss prevention efforts. Rogaine and biotin and not significant therapies to stop serious hair loss. I hope this information is helpful to you.Kind Regards,Ken Anderson, MD, FISHRS, ABHRSBoard Certified Hair Restoration Surgeon
