This report describes two cases where patients developed alopecia while undergoing treatment for psoriasis with IL-17 inhibitors, suggesting an unexpected paradoxical reaction.
research Maintenance of optimised hair growth from viable terminal scalp hair follicles at baseline with oral finasteride in male pattern hair loss and first evidence of a “drug dependency” and a post-finasteride “rebound effect”.
This study found that male pattern hair loss worsened significantly after stopping finasteride, revealing a "rebound effect" where terminal hair transformed into miniaturized hair over 30 months off the drug.
research Oral administration of Lactilactobacillus curvatus LB-P9 promotes hair regeneration in mice
This study found that in mice, oral administration of Lactilactobacillus curvatus LB-P9 accelerated hair regrowth and increased hair thickness, hair follicle numbers, and dermal thickness, likely by boosting hair growth factor production and dermal papilla proliferation.
research The Circular RNA CircCOL1A1 Functions as a miR-149-5p Sponge to Regulate the Formation of Superior-Quality Brush Hair via the CMTM3/AR Axis
This study found that the circular RNA circCOL1A1 influences the formation of superior-quality brush hair in white goats by regulating hair follicle stem cell behavior and interacting with the miR-149-5p/CMTM3/AR axis.

Deoxyribose sugar gel may stimulate hair regrowth similarly to minoxidil by enhancing blood supply and follicle activity. Human trials are necessary, and current products have mixed results.
community Hair Loss “Cure” for Inflammation: Topical Roflumilast
Topical roflumilast is effective for reducing inflammation in various scalp conditions like seborrheic dermatitis, psoriasis, and eczema, but not proven to stop scarring alopecia. Alternatives like apremilast and Vtama are also discussed for their anti-inflammatory benefits.
community Dutasteride absolutely nukes hair DHT
Dutasteride significantly reduces DHT levels, potentially more effectively than finasteride, and is used to treat hair loss. Some users report side effects like reduced libido and mood changes, while others experience hair regrowth and increased testosterone.
community There’s nothing better on the horizon [RANT]
There is skepticism about new hair loss treatments, with the belief that current options like minoxidil, finasteride, and hair transplants are the best available. Concerns are raised about the systemic side effects of androgen-related treatments, even those marketed as topical, and doubts about the effectiveness of emerging treatments like clascoterone.
community PP405 (Everychem 3HP) Anecdotes - Please assemble and share your story
PP405 (Everychem 3HP) may help with hair regrowth, with mixed user experiences. Users often combine it with minoxidil and finasteride, but there are concerns about its efficacy and side effects.

10 / 801 results- How does spironolactone help reduce hair loss when used in topical or oral treatments? Studies report that spironolactone slows androgen-driven follicle miniaturisation by blocking androgen receptors, with most evidence in women and mostly alongside minoxidil; it is a prescription drug and its use for hair loss is off-label.
- How is valproic acid being explored differently in topical hair products compared to its traditional oral medical use? Topical valproic acid is being studied for local effects on the hair follicle rather than the whole-body effects of the oral drug. The human evidence is one small randomized 24-week trial of an 8.3% spray; no topical valproate product is approved for hair loss.
- How often should sulforaphane-based products be used for hair loss prevention? No human trial has tested sulforaphane for hair loss prevention, so there is no established usage frequency. Oral supplements are taken daily in research on unrelated conditions and the hair-specific evidence is limited to cell, mouse and isolated-follicle studies, so any schedule is extrapolation rather than a dosing guideline.
- Is metformin used topically for hair loss, or only as an oral tablet? Approved metformin products are oral tablets only; there is no approved topical metformin for hair loss. Published human reports of topical use are a handful of uncontrolled, pharmacy-compounded case reports in scarring alopecia, and the most-cited clinical series actually used the oral drug.
- Is white tea more effective in topical hair products or as an oral supplement for hair growth? Neither topical nor oral white tea has any human clinical trial behind it for hair growth. Topical use has a more direct mechanistic rationale, but the only verifiable studies are a cell-culture EGCG experiment and a pharmacokinetic study with no hair outcomes.
