How much less effective is PRP Injection without Acell for hair thinning?

in my practice we do PRP injections with progesterone.  We didnt find Acell to be that effective.  Best, Dr. Emer.

The results of ACell and PRP probably factors around the cost more than the results since there are no clear consensus on even if it works as advertised. As long as you understand there is no such thing as "stopping" genetic hair loss and that you need to pay a fee to continue with either treatment indefinitely it is a decision best made between you and your doctor.

This is a terrific question... . In my opinion, PRP with Acell is proven to work with hair transplantation. There are no studies demonstrating that a Acell is necessary with PRP to increase hair thickness or decrease hair loss. Although we are now going to start a multicenter study, my experience is that PRP lasts for approximately 4 to 6 months without repeating injections or adding Acell.I hope this helps! Good luck!

Many physicians, including myself, don't use ACell. Studies have yet to show benefits with Acell and PRP vs PRP alone. The most important factors appear to be the concentration of PRP used and the method of administration. 

This treatment is not scientifically proven to improve hair loss. If there is any effect it is very temporary and you need to repeat it every one or two months. It is best to consider an overall permanent plan to help with your hair loss.  

Acell is a proprietary chemical meant to form a skeletal matrix so that the PRP can attract cells to it.  There is no independently reproduced scientific article showing Acell as more effective in stimulating hair growth than PRP alone.  For that reason I do not like to use Acell.
