Is there any benefit or side effect of PRP on scalp? I am losing my hair and have scalp itching.

Hello,
Prp is a natıral treatment. Do not wash your head after the treatment for 1 day. It can cause some pain and dizzyness at first but not other side effects

Your question concerning if there is any benefit to PRP is interesting.  There are thousands of people who have asked questions on realself where the surgeons answered explaining the benefits.  Studies continue to get published as well showing benefits like increased fullness, etc...  If you are asking if you would benefit from it, please repost with some photos so we can have a better idea of what your scalp looks like.

Several meta-analysis have been performed and published in the dermatologic and hair restoration literature supporting the use of PRP. The benefits are increased when there has been a short duration of hair loss. This is often the case in younger individuals. PRP has been shown to increase the density of existing hair up to 30%, increase regrowth up to 30%, and decrease shedding. As with any other procedure, results vary per individual. PRP is anti-inflammatory and can improve signs of inflammation such as itching of the scalp. It can be combined with other methods such as topical steroids and dandruff shampoos.Find a dermatologist who is a PRP expert.

PRP treatments are fast growing in popularity. While there is a good deal of anecdotal data on its positive effects, there is very little randomized controlled (i.e. high quality) data available. With respect to hair restoration, proponent have demonstrated impacts ranging from slowing/cessation of loss to thickening/strengthening of hair. Some will claim to have demonstrated regrowth.
Ultimately, there is very little drawback or risk to the procedure with the potential for significant reward. While the mechanism of action is not entirely clear, the effect will likely be rooted in the native concentration of growth factors in any given patient's plasma. Some will have better quality or more concentrated plasma than others. The results range from decreased hair loss to thickening of existing or emerging hairs to increased growth. Ultimately, the variability in response is likely linked to the inherent (i.e. genetic) quality of the plasma which will differ from one patient to the next.
PRP has (anecdotally) proven to be effective in the arena of hair restoration both as an adjunct to grafting as well as standalone treatment for those who may not (yet) be a candidate for grafting. Patients have demonstrated slowed loss, thickening of existing hair and regrowth. The typical duration of effect is 6-9 months with most patients being treated 2x yearly (at least initially).

In my experience, it is a nice option for young people who have yet to reach a stable hair pattern (i.e. not ready for FUE grafting/Neograft) and are looking for an adjunct to traditional medical therapy. That being said, it is important to limit your expectations as not everyone experiences regrowth at the same pace (or at all). However, anecdotally speaking, everyone seems to gain some benefit with regular treatments (annually to bi-annually after 3 treatment induction).
With regards to your specific question, it is unclear if PRP will address pruritis/itching. This might warrant dermatologic evaluation to rule out other causes.

PRP has many wonderful benefits for hair loss.  The  growth factors present in patient derived platelet rich plasma stimulate hair to stay in the growing phase which improves density and thus the appearance of hair.  It also has anti inflammatory properties and can improve the blood supply to support hair follicle growth.  There are minimal side effects and risks.  Some patients may experience mild swelling and feel a heaviness post injection but this subsides quickly.  In your particular case I would recommend seeing a qualified physician to evaluate your hair and address all of your concerns. 

Hello and thank you for your question. I’m not sure PRP is what you need. I think you really should be seen by a hair loss professional in order to determine what is going on. After that you can determine if PRP is what you need. I wish you the best.Dr. T

Excellent question. The correct technique with PRP MAY help but I won't recommend any treatment at the moment. First of all, you need a hair loss diagnostic. I will suggest you to book a consult for a complete scalp and general evaluation with a local and experienced hair loss specialist. Good luck.

If done properly and you are injected with your own PRP and they follow proper protocol, there should be little to no risk. you should plan at least 3 sessions, spaced a month apart. no one can predict your results. You must have some hair growth in the area being treated. Studies show both an increase in the number of hair follicles, as well an increase in the density of the hair itself.david berman md
