Prostaglandin D2 Inhibits Wound-Induced Hair Follicle Neogenesis Through the Receptor Gpr44

DLQ01, a prostaglandin F2α analog, shows promise for hair growth by directly stimulating PGE2/PGF receptors without needing conversion, and can be combined with minoxidil and retinoids like tretinoin for enhanced effectiveness. Minoxidil's efficacy may be reduced by COX-1 inhibitors, but using prostaglandin analogs like Latanoprost or Bimatoprost can help maintain its effectiveness.

Hair loss may be linked to the GPR133 receptor, independent of the androgen receptor pathway. Treatments like finasteride, dutasteride, minoxidil, RU58841, and KX-826 show varying results, with hair loss persisting due to high testosterone and GPR133's role.

Elevated PGD2 levels in bald scalp tissue may contribute to hair loss, and treatments like castor oil, finasteride, and minoxidil are discussed as potential solutions. Some users explore alternatives like oral castor oil and cetirizine for those who cannot use finasteride.

The conversation discusses using PGE2 as a hair growth stimulant, comparing it to minoxidil, and considering the addition of Setipiprant. Concerns about side effects like skin damage and cost are also mentioned.

The conversation discusses a community called PHG, which focuses on experimental hair loss treatments and scientific approaches to hair regrowth. It mentions treatments like Minoxidil, finasteride, and RU58841, and highlights interest in new treatments like Setipripant, Histogen, and Replicel.

Various hair growth treatments were discussed, including microneedling, bimatoprost, setipiprant, stemoxydine, PGE2, CB-03-01, WNT Beta-Catenin upregulators, KY19382, topical estrogen, IGF-1, GH, MK-677, oral castor oil, fisetin, resveratrol, cetrizine, and lactic acid. Users shared experiences and sources for these treatments, with some expressing interest in topical solutions and others noting the lack of FDA approval or scientific evidence for certain options.
