I had a FUE transplant 8 weeks ago, is it ok to use Rogaine now? Does it thicken my normal hair?

It is best to ask your surgeon about post operative care as each doctor has their unique regimen.   Rogaine probably would not thicken your existing hair.

If there are no other contraindications such as irritation, allergies, dizzy spells, etc with the use of topical minoxidil, it is often safe to begin using it with weeks of your transplant. At 8 weeks, you should be okay using it. There are potential benefits that could include reducing the incidence of shock loss as well as promoting yield of grafted hairs. 

I recommend to start to use Minoxidil after 10 days for my patients. Yes it will help your existing hair. Finasteride (Propecia) is extremely helpful also. If in doubt please discuss with your surgeon as this should have been on his/her aftercare.

Thanks for your question. I recommend my patients to start with Rogaine 20 days after the surgery and it should be applied 2 times a day.

You can start to use minoxidil and other hair growth supportive drugs or food supplaments  (those contains biotin, zinc, folic acid, methionine, saw palmetto etc) 2 weeks after surgery. 

Thank you for the question. In answering your question, being 8 weeks post procedure it is absolutely safe in starting Minoxidil and highly recommended to use indefinitely. 

This is a question that really just depends on the specifics of the patient's procedure as well as just the doctor's personal preference, so it would probably be best just to ask yours. However, it's safe to start using it once your scalp is fully healed, which would generally be under a month.

It is recommended that you initiate minoxidil a week post procedure and continue for at least 12 months; 

minoxidil can be used once the crust are off.  I have studied minoxidil and found that it offered no value to the new grafts that were transplanted
