Way to grow out hair? Would PRP treatments work - Am I too young? (photos)

Based on your photos and description PRP will not give you the results you are looking for.The only way to significantly increase the hair density in that area would be with a transplant.

A combination of hair growth treatments are usually needed to get the most improvement. I suggest seeing a hair growth expert now to go over your blood test results and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone. See an expert. Best, Dr. Emer

In my opinion, 20 years old is not too young for PRP. It is hard to predict whether PRP will extend your hairline. If this is your normal hairline and not a result of hair loss, most likely PRP will not change your hairline. It usually make your hairs thicker.PRPHAIRMD.COM 

PRP Treatmens will certainly help regrow the small miniaturized baby follicles and I think that it would really help make a big improvement. PRP is a prevention that rejuvenates the hair making it thicker and stronger.   

While I am hesitant to make a definitive recommendation without thoroughly examining the area in question and getting more information about your medical history, I can say that it is possible for platelet rich plasma therapy to stimulate thicker hair growth in specific areas of the scalp. All hair grows in cycles, and the length of those cycles is one of the factors that determine how long hair will get. For example, hair on the scalp generally has a longer growth cycle than body hair, and so grows to a greater length. Platelet Rich Plasma works by causing hair follicles to become healthier and larger and by accelerating the transition of the hair follicle from the dormant (telogen) state back to the actively growing (anagen) state.  Theoretically, if platelet rich plasma is injected into follicles that are producing only small, fine hairs, longer and thicker hairs could result.
That being said, it is important to understand that platelet rich plasma cannot cause new hair to grow where none has ever grown before. In all likelihood, it will not change the shape of your existing hair line, especially if you have not been experiencing any prior hair loss or thinning. Platelet rich plasma can be safely performed on patients of any age and has, in fact, even been used to treat certain forms of hair loss in children. However, it still has potential risks and side effects that do need to be taken into consideration. Finally, platelet rich plasma therapy is a procedure that requires ongoing maintenance. We generally recommend that patients undergo a set of three initial treatments six weeks apart followed by a repeat treatment one year after the first. In your case, additional follow up treatments may be required in order to maintain your results.

PRP treatments are definitely effective but you may require few treatments for best modality. You may also want to look into cold laser hair therapy which uses cold laser to stimulate hair follicles and help with shedding and thinning.  A good effective laser on the market right now is LaserCap.

PRP will not advance your hairline where there has never been any hair. It can encourage thicker hair growth in areas that are thin however.

PRP can restore hair growth to areas where follicles have stopped producing hair over the past five years, and needs to be repeated periodically.  It cannot create new growth where you have never had hair. 

Young patients with true hair loss can recover their hair remarkably well with PRP treatment. We generally advise that patients use a prescription-strength topical minoxidil mixed with proteins (to help absorption) to support treatment efficacy. 

PRP is a restorative regenerative treatment that improves the tissue it is injected into.  In the hair restoration field, it shows great improvement in healing post procedure and can also be used annually (depending on the method used) to reverse the aging process of follicles.
