Any additional ways to stimulate hair growth post FUE? (photo)

I perform FUE almost exclusively in our center with great success. The key is primarily patience. Transplant results can manifest in up to 12-18 months. As part of the post-treatment protocol, many of my patients use minoxidil and/or finasteride. In addition, we offer to every patient low-level light therapy at 630 and 550 nm wavelengths to augment oxygenation of the tissues and scalp remodeling. Wearing a hat after the first few weeks should not impact results. Hang in there!

With any hair transplant procedure, patience is crucial. The transplanted hairs will only be starting to become visible six months post-transplant, and take at least a year to fully mature. At the one year mark, the final result should begin to be evident in most cases. 
Other things that I use in my practice to help speed the maturation process, improve the overall transplant result, and prevent future hair loss include minoxidil, finasteride, topical shampoo/serum/conditioner treatments, and PRP injections. 
All the best,

There isn't much you can do to stimulate hair growth.  It generally takes 6 to 12 months to see results.

You will usually see hair start to grow 4-6 months after hair transplantation. At 6-8 months 60% of the hairs will be growing. At 12 months 80-90% of the result will be visible. Full results can be expected at 18 months. The following have been proved to stimulate hair growth after transplantation:PRP (Platelet Rich Plasma) injectionsLow level laser (Hairmax comb or similar)Formula 82M (stronger than Rogaine)Rogaine

After a Hair Transplant treatment you’ll be able to see your new hair line immediately, but it will take a little while longer for you to reap the benefits of your final results. Everyone’s hair is different, meaning the exact process you’ll go through to see your results will vary massively from everyone else. Your hair will still grow at its normal rate so it’s crucial to remember that undergoing a transplant treatment will not change this and there’s no magic button to speed up the frustrating process. In this period you may support your new transplanted hairs by using Rogaien,Minoxidil and maybe Prp injections . ]All the best
