Will PRP help regrow my baby hairs on my hairline? (Photo)

PRP works best to reverse the miniaturized hair and strengthens the hair that you have. As long as your hair follicles are alive, PRP will help. 

PRP hair injections should definitely create an improvement on hair growth.  It may take more than one treatment in your case but commit to it and the benefit will be noticeable as time goes on.  You should also be taking some hair growth vitamins.  Nutrafol is a great choice as far as vitamins to add to the success of your procedure.    Find out if your provider mixes a tiny amount of Calcium Gluconate with Plasma.  This Calcium activates the plasma once is injected enhancing your results.

Good quality PRP will increase hair density 50% in 6 months.  However, this does not mean your hair will return to it's long normal length.  However, this is possible because good PRP promotes anagen.  Unfortunately, many clinic use PRP kits that are not really PRP.  It is doubtful you will respond to these cheap imitations for PRP.  
Once the hair gets to a certain degree of miniaturization, nothing seems to bring those follicles back, though we have seen outstanding results from topical finasteride compounded in Italy recently.  You have to remember the primary value to PRP is to keep the follicles in anagen or the growing phase.  Once the follicles move into the telogen or resting phase, inflammation begins and continues for the entire time the follicles rest (months).  this inflammation over time wipes out stem cells so that follicles cannot regenerate any longer.  Once this happens, the follicles are lost forever.  With good PRP you are trying to keep the follicles alive as long as possible.  Remember, the follicles behind these on the hairline are the ones you are trying to protect.  The ones on you hairline may be too far gone to see much benefit from PRP.  

It's good that you're getting after this situation so young. I think you need to be patient and make sure you're doing other things to improve hair growth. You should consider Minoxidil and talk to a specialist to see if an androgen blocker can help. In the future, you will likely need more treatments as hair loss is a lifetime issue. Good luck.

Hello. I would suggest you give your treatments a little longer before determining that you have not responded.  I also recommend 6 monthly treatments followed by 1 treatment every 3 months after that. You should definitely be on a protocol including the Viviscal marine supplement and perhaps even prescription topicals or medications or hormonal therapy, depending on the situation. Not everyone responds to this treatment but many do. Good luck!

PRP  has the ability to decrease hair shedding, speed the growth of hair, increase the diameter of the hair shaft, and regrow hair  when the follicular units are present. The increase in diameter reported by a recent study was 30%. In summary, PRP may reverse the miniaturization at your hairline. Find a PRP expert. Ask to see photos.

Prp is effective, but I have a very specific protocol, every 3-4 weeks for 6 months with prp therapy.  I also add in progesterone to speed the healing process.  After that the injections are tailored down.  You should also be on viviscal and other growth promoting ingredients. See an expert for a formal evaluation. Best, Dr. Emer

Hello, Thanks for sharing your pics. Though PRP has shown promising results its not effective in all only around 60% respond to it. The results of PRP is initial reduction in hair fall and later you can see increase in hair density. This may take 4-6 sessions and around 6 months to see some visible difference. Followup with your plastic surgeon.

As long as you have some healthy hair follicles then PRP should be able to help regrow some hair

If you have active hair follicles in this area as determined by a consultation, PRP can help restore hair growth with or without amnion or acell.  I recommend Rogaine also in combination with some vitamins and supplements.
