    TLDR Latanoprost can make eyelashes longer, thicker, and darker.
    The document from 2002 examines the effects of latanoprost, a prostaglandin analog, on hair growth, particularly eyelashes. It was found that even brief treatment with latanoprost can result in longer, thicker, and more pigmented eyelashes, with some effects lasting up to 14 months post-treatment. A prospective study with 43 patients showed a mean increase in lash length of 19% in the treated eye. Latanoprost is thought to induce the anagen phase in resting follicles and prolong this growth phase. The document also discusses the potential of latanoprost for cosmetic use and its comparison with other hair growth agents like minoxidil and finasteride. While latanoprost has been shown to reverse eyelash alopecia, its effects on scalp hair loss have not been systematically studied, and further research is needed to understand its mechanisms and therapeutic potential for different hair follicle types.

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

      in Research/Science  3 upvotes 8 months 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.

      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 Don’t Get Too Hyped About PP405. We've Seen This Movie Before.

      in Research/Science  214 upvotes 5 months ago
      PP405 is a new hair loss treatment showing early promise with a 20% hair density increase, but skepticism exists due to past failures of similar treatments like Pyrilutamide, RU58841, and Bimatoprost. Users debate its potential effectiveness, with some hopeful due to Google's involvement, while others urge caution without more evidence.

      community Medications that cause extra hair growth

      in Research/Science  123 upvotes 2 years ago
      The post discusses the side effects of various drugs causing excess hair growth, questioning why only minoxidil is used in the hair loss industry. The conversation includes users sharing their experiences and concerns about potential side effects of these drugs, with some preferring baldness over potential health risks.
