Tips to increase growth after FUE treatment?

There are no specific tips to help grow your hair faster after a surgery.    If your surgery was a success your hair will grow over the next 6 to 12 months.

Generally, if an FUE procedure is done correctly, the grafts will grow.  However, I have noticed patients who do PRP procedure post hair transplant tend to have earlier graft growth and sometimes less shedding.  I haven't read any medical articles or journals with proper studies, however this is just based on my experience.  Its definitely not necessary to do anything other than patiently wait.

Anything that people use to boost the growth of hair following FUE has its potency debated. Some say PRP really helped but there's been no studies that confirm it makes a difference. Laser therapy is also debated, so are lotions etc. that claim to increase post-op growth. These methods certainly won't hurt to try if you look into them and think they may be right for you, but they come with even less of a guarantee than the transplant itself.

you are still very early at the 3 month mark after FUE. The hair has to go through its cycle before it starts to grow after a transplant. Be patient! Preventative medications are key to helping you keep your native hair. If you have any concerns about your transplant, it is best to discuss this with the surgeon who performed your transplant.

I typically recommend patients to begin Finasteride, Minoxidil and Laser therapy after the procedure.  Apply Monoxodil post procedure seems to keep the hair in the growth cycle.  Another option to accelerate growth is PRP.  Contact your surgeon to see which option is best for your situation.
