Evaluation of Utility of Phenol in Alopecia Areata

    TLDR 88% phenol is effective for treating alopecia areata.
    The study evaluated the efficacy of 88% phenol in treating alopecia areata (AA) in 50 patients aged 7-45 years with nonscarring patchy hair loss on the scalp. Patients received phenol applications every 3 weeks, and hair growth was assessed based on texture, pigmentation, and density. Results showed significant improvement in hair texture and pigmentation by the 9th week, and steady improvement in hair density from the 9th week onwards. By the end of the study, 78% of patients exhibited good to excellent hair regrowth, with no poor responses. Side effects were minimal, including temporary hypopigmentation in 10% of patients and hyperpigmentation in 6%. The study concluded that 88% phenol was an effective, low-cost treatment for stable AA.

      community Looks like a real cure to the root of baldness (DHT-induced senescence) was proven earlier this year

      in Research/Science  735 upvotes 2 years ago
      A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.

      community What is the consensus on topical tretinoin mono therapy?

      in Research/Science 2 weeks ago
      The conversation discusses the effectiveness of topical tretinoin as a monotherapy for hair loss, with users suggesting it may not be as effective as minoxidil or finasteride. The original poster is considering other options like a phenol peel and is concerned about the risks of derma rolling.

      in Finasteride/Dutasteride  52 upvotes 1 year ago
      The effectiveness of Dutasteride compared to Finasteride in treating hair loss, with evidence given such as studies and experiences, as well as discussion around whether one should switch from Finasteride to Dutasteride. There is also a discussion on post-Dutasteride syndrome.

      community The theory that explains everything. Please help me make this big!

      in Research/Science  2452 upvotes 3 years ago
      The post and conversation are about the role of the enzyme 3alpha-hydroxysteroid reductase in hair loss and the potential of compounds like procyanidin B2 and sulforaphane to boost its activity for hair regrowth. Further research is needed to develop effective treatments based on this theory.
