4 months has gone for FUE hair transplant but not even 5% result on my scalp.

Thank you  for posting your question. At only 4 months out, it might still be too early to call your procedure a failure. It takes anywhere from 3 to 4 months to see the slightest change, wait until month 6 to judge. Some patients get quicker growth, and others take a bit longer. At 6 months you should be at 50% growth and full results can take up to 12 to 14 months if not a bit longer. Hope this helps. Meanwhile you may want to consider PRP, Minoxidil 5% Topical and possibly Finasteride oral or topical if you can.

Evaluating a hair transplant result as a failure you should wait at least 10 months. On the 4th month it is possible to see very little or no growth.The best option is visiting your doctor and take it easy.
