    Nope, that wasn't established. Multiple articles on the PubMed.gov Website (US National Library of Medicine National Institutes of Health) state that PGD2 inhibits platelet aggregation. One example, read the last paragraph here.

    Studies indicate that miniaturizing follicles are saturated with high concentrations of PGD2 whereas follicles in the "safe" zone on the same guy do not have those concentrations of PGD2. Platelet rich plasma increases the hair shaft diameter of miniaturized hair. To me, this observation is worthy of further investigation:

    "We show a close temporal relationship between elevations in both Ptgds mRNA and PGD2 levels in mice with hair follicle regression during normal hair follicle cycling. We further provide functional data indicating that PGD2 and its nonenzymatic metabolite, 15-deoxy-Δ12,14-prostaglandin J2 (15-dPGJ2), inhibit hair growth in both mouse and human hair follicles. In mice and humans, the PGD2-mediated inhibition of hair growth required the G protein (heterotrimeric guanine nucleotide–binding protein)–coupled receptor 44 (GPR44), but not the prostaglandin D2 receptor 1 (PTGDR). Finally, we describe a mouse model (K14-Ptgs2) with elevated PGD2 levels in the skin that phenocopies human AGA (14). These results implicate PGD2 in the pathogenesis of AGA and suggest new receptor targets for its treatment."

    Dr. Cole began using PRP during hair transplant surgeries, because it speeds and improves healing. Every patient who comes in for hair transplant surgery with adequate hair length gets cross section trichometry. Cross section trichometry is validated as a legitimate method of determining hair mass here on the US National Library of Medicine National Institutes of Health Website.

    We keep every patient's hair mass index saved in a spread sheet. In about 90% of all cases where PRP/ACell was administered during their hair transplant surgery, we later see some increase in the hair mass index.

    From the US National Library of Medicine National Institutes of Health:

    http://www.ncbi.nlm.nih.gov/pubmed/22455565

    "BACKGROUND:
    Recently, autologous platelet-rich plasma (PRP) has attracted attention in various medical fields, including plastic and orthopedic surgery and dermatology, for its ability to promote wound healing. PRP has been tested during facelift and hair transplantation to reduce swelling and pain and to increase hair density.
    OBJECTIVE:
    To investigate the effects of PRP on hair growth using in vivo and in vitro models.
    METHODS:
    PRP was prepared using the double-spin method and applied to dermal papilla (DP) cells. The proliferative effect of activated PRP on DP cells was measured. To understand the mechanisms of activated PRP on hair growth, we evaluated signaling pathways. In an in vivo study, mice received subcutaneous injections of activated PRP, and their results were compared with control mice.
    RESULTS:
    Activated PRP increased the proliferation of DP cells and stimulated extracellular signal-regulated kinase (ERK) and Akt signaling. Fibroblast growth factor 7 (FGF-7) and beta-catenin, which are potent stimuli for hair growth, were upregulated in DP cells. The injection of mice with activated PRP induced faster telogen-to-anagen transition than was seen on control mice.
    CONCLUSIONS:
    Although few studies tested the effects of activated PRP on hair growth, this research provides support for possible clinical application of autologous PRP and its secretory factors for promotion of hair growth."


    Another from the US National Library of Medicine National Institutes of Health:
    Quote:
    "The beneficial effects of PRP in AGA can thus be attributed to various platelet-derived growth factors causing improvement in the function of hair follicle and promotion of hair growth. It is safe, cheap, and non-allergic and it appears to be a useful adjuvant in the management of AGA."

    My theory... Perhaps PGD2 plays a role leading to a deficiency in platelet growth factors necessary for healthy hair growth. In the better cases where PRP is administered, we see miniaturizing hair shaft diameter improve significantly.

    Fellas,

    Finished two treatments, with different doctors (two treatments in total, not 2x2). Both doctors are very well regarded. I can honestly say I gave this treatment an honest shot. Two treatments 6 months apart, and waited 6 moths after the second before posting again. For me the results were zero. My hair loss has progressed. I don't want to attribute the progression to PRP because that would be an unfounded accusation but can confidently say there were no positive results. I know there is a growing body of science in favor of this treatment, but wanted to add my anecdotal response on its lack of effectiveness. I'm now (like everyone else here) hoping that something in the pipeline comes to market at breakneck speed. Good luck out there!

    I have seen it done on a friend but he had to go 4 times over 12 months, there was some positive result although slow he did retain the hair he had

    I had 2 PRP treatments, 6 months apart. I grew some peach fuzz. For the money I spent on PRP, the results weren't worth it. I've heard many people report peach fuzz growth with Rogaine. I spent $3200 on 2 PRP treatments. $100 worth of rogaine would've given me the same results.
    About 5 months ago I started using a Derma Roller once a week which does the same exact thing as PRP, promotes wound healing/growth factors. My $10 Derma roller has given me MUCH better results then $3200 worth of PRP treatments.
    I think it's safe to say PRP is just another way for doctors to suck our wallets dry.

    Dont ever go with this, i have lost around 30 % hair in 4 months due to this i was hoping a 10% increase and now i dont know when will this shedding stop , its utter crap, dont use it until it is proven that it has no negative effects.

    I just don't think that they are using nearly enough PRP growth factors to make any significant difference. I think when they developed it, they just excepted in to help with hair transplantation and not much else. I believe that if a doctor truly tinkered with the PRP procedure and designed it to be a true hair restoration treatment, and not simply some complement to hair transplantation, it could really make a true difference.

    My opinion as well.

    We have also noted a number of patients benefit from prp treatments. Improvements in hair caliber were observed at the six-month mark.

    "A number of patients"? Can you provide us with more specific statistics and hair counts? I personally think PRP is just jargon. They shoved a bunch of crap into a solution that they thought should have worked.. the evidence to support anything positive is very minimal. I also believe that the injections can cause enough trauma to trigger TE, which is an absolute nightmare, especially if you have MPB

    "Hair caliber" can sometimes be a meaningless statistic, and can be misleading to patients (even if it's not intended to be). It's quite possible for hair caliber to increase, but the results are not a visible improvement for the patient.
