What treatment suits me best? I took 1 PRP treatment in September, and now 5 months later I don’t see big differences (Pohto)

PRP scalp injections work very well for hair regrowth by awakening the sleepy hair follicle.  The plasma is injected 0.3 to 0.5mm deep and even within 4 weeks there is a thickening of hair on injected area.  With all that said, it is recommended to do a minimum of 3 treatments, or a treatment a month for 3 months.  You should have return to your provider to have pictures and better be able to tell if there was any new growth.   Going 5 months without a treatment is not a good idea at all unless you had already benefited from the treatments.  Stick to one treatment a month at least 3 times and I bet you will see a difference. 

To get any decent result with PRP you need a series of treatments preferably four or more a month apart and to expect results at the 6 month mark. So don’t be surprised you aren’t getting results. I would also combine your PRP treatment with topical agents and even laser therapy.

With only one PRP session you won't get a solid result. You would have to get the injections on a regular basis periodically. You can continue with your PRP ınjections or şf you are looking for a permanant solution you can consider FUE

A:  First, don’t beat yourself up over your choice of products as a teenager, they are probably not to blame and just because they were inexpensive doesn’t mean they were bad.  Genetics are usually to blame for male hair loss. PRP is a rather new medical therapy and we don’t yet know who responds best to it or how much a patient may respond.  It’s definitely a safe alternative to surgery especially because you are young and your pattern of thinning is not established.  As with any non-surgical treatment, it will require regular maintenance after the initial sessions have been performed.  In our office we recommend 3 sessions initially then maintenance every 4 to 6 months.  It is a good idea to consult with a board certified dermatologist if there is any doubt about the cause of your hair loss and your options for hair regrowth.  Good Luck!

PRP is very effective is done the allocated number of times. We suggest a minimum of around 4 treatments. Typically the hair cycle is about 12 weeks so only having one treatment is not going to be enough to see any changes. If you are looking at continuing with the PRP hair treatment then I would recommend having all 4 treatments

Many people need more than one treatment with PRP for hair growth.  So it does not mean it didn't work if you didn't get much result from just one session.  I would recommend at least 2, but may be even 6 treatments in a year.  Your protocol should also include a topical agent as well as a medical grade laser cap to enhance the results.  Good luck.

One PRP treatment is rarely enough to improve hair loss.  Most physicians recommend a series of monthly treatments.  Sometimes oral or topical medication is recommended in addition.  I doubt that a hair wax caused you to lose hair.  You are a man in your 20's and that is when androgenic alopecia begins to take effect.  Go back to your dermatologist for further treatment, or you can begin topical therapy with Rogaine (topical minoxidil) if sold without prescription in your country.
