Glossary Prostaglandins

group of lipid compounds with hormone-like effects in the body

Prostaglandins are a group of lipid compounds that are derived from fatty acids and have hormone-like effects in the body. They play a crucial role in various physiological processes, including inflammation, blood flow, the formation of blood clots, and the induction of labor. Prostaglandins are also involved in the regulation of hair growth and can influence conditions like alopecia.

community You will lose hair if your prostaglandins aren't in balance

56 upvotes 1 year ago

Prostaglandin balance affects hair loss, particularly in conditions like Lichen Planopilaris, where an imbalance can lead to hair follicle damage. Treatments mentioned include prostaglandin analogs and Pioglitazone HCL, with a focus on maintaining prostaglandin equilibrium for potential hair regrowth.

community Has anyone here tried topical synthetic prostaglandins (Bimatoprost, Latanoprost, cetirizine) to stimulate hair growth?

6 upvotes 2 years ago

The conversation discusses using topical synthetic prostaglandins like Bimatoprost, Latanoprost, and cetirizine for hair growth. The user shares a link suggesting these treatments may be effective.

community DLQ01: A Better "Minoxidil" PGF2a synthetic analogue.

3 upvotes 1 year ago

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.

community Mechanism of Action these drugs re-grow hair?

2 upvotes 2 years ago

Minoxidil, finasteride, and RU58841 promote hair growth by different mechanisms, with minoxidil and prostaglandin E1 being specifically mentioned. Corticosteroids can also cause hair growth.

community Need supplemental products in addition to oral minoxidil and oral dutasteride

1 upvotes 1 year ago

The user has been using oral minoxidil and dutasteride for hair loss without success and is considering adding topical 17α-estradiol, Pyrilutamide, Clascoterone, or cetirizine. They have confirmed low serum DHT levels and are exploring additional treatments due to genetic sensitivity to DHT and prostaglandin D2.

learn Cetirizine

popular antihistamine showing promise for hair loss as an anti-inflammatory and prostaglandin inhibitor

How does cetirizine reduce inflammation linked to hair loss? Cetirizine is proposed to lower prostaglandin D2 and raise prostaglandin E2 around hair follicles; three small trials of a compounded 1% topical report modest increases in hair density and shaft thickness, with minoxidil doing better head-to-head. Topical cetirizine is off-label and unapproved for hair loss, and the evidence is too thin to call it effective or safe.

learn Setipiprant

How does Setipiprant work on the scalp to potentially promote hair regrowth? Setipiprant blocks the DP2 (CRTH2) receptor that prostaglandin D₂ acts through, and PGD₂ is reported to be elevated in balding scalp — but the one published placebo-controlled trial in men (DuBois 2021, n=169) found no significant hair regrowth. It is an experimental compound, not an approved hair-loss medicine.
What is Setipiprant and how does it differ from DHT blockers like finasteride or dutasteride? Setipiprant blocks the prostaglandin D2 receptor DP2 rather than the DHT pathway that finasteride and dutasteride act on. The one published human trial — a 169-man, 24-week phase 2a study at 2,000 mg a day — reported no statistically significant improvement in hair density over placebo, and setipiprant is not an approved hair-loss medicine anywhere.

learn Latanoprost

glaucoma medication with hair follicle stimulant effects

How does latanoprost work to make eyelashes and possibly scalp hair grow? Studies report that latanoprost, a prostaglandin analog, lengthens the anagen (growth) phase of hair follicles, which is the mechanism given for the eyelash thickening seen in glaucoma patients; on the scalp the evidence is one 16-man pilot study and animal work, so the effect there is unproven.
