community Eirion Therapeutics Announces Potential Breakthrough Treatment for Hair Loss Based on First-in-Man Clinical Trial Results

in Update 415 upvotes 1 year ago

ET-02, a new hair loss treatment, shows promising results with a 6-fold increase in hair count, potentially outperforming minoxidil by activating stem cells in hair follicles. Further trials are ongoing to confirm its efficacy and safety, with potential market release in the future.

community Summary of Procapil video by Haircafe

2 upvotes 1 year ago

Procapil is marketed as a natural hair loss treatment but lacks strong evidence and is industry-biased. Minoxidil and Finasteride are the only FDA-approved treatments for androgenetic alopecia.

community Is finasteride just not working for me? test results

3 upvotes 1 year ago

A 21-year-old is experiencing aggressive hair loss and questions the effectiveness of finasteride after 45 days of use, with high DHT levels. A user advises that scalp DHT, not serum DHT, is important for hair loss assessment, and suggests monitoring hair improvement over time.

community My personal experience/observations fighting AGA seriously for 5 years

50 upvotes 1 year ago

Minoxidil with alcohol and propylene glycol was more effective than non-alcohol versions, and RU58841 worked best in a non-water-based solution. Oral finasteride showed better results than topical, despite side effects; microneedling and tretinoin worsened hair loss, and PRP was only helpful when younger.

community The time I went to a hair clinic in 2020

2 upvotes 4 months ago

The conversation discusses hair loss treatments, with a focus on PRP, which is viewed skeptically. Minoxidil and finasteride are recommended as more effective options.

learn Procyanidin

Are Procyanidin based hair tonics or shampoos effective against androgenic alopecia? Three small trials of topical procyanidin in 29 to 43 men, all run by the company that developed it, reported modest hair-count gains after four to six months. No independent trial has confirmed them, and procyanidin is not an approved treatment for pattern hair loss.

learn Centella

Could a flaxseed-based hair mask help fight off the DHT effect in your scalp? There is no verifiable evidence that flaxseed lowers DHT or that its lignans penetrate the scalp; a flaxseed gel mask is a cheap emollient that may soothe an irritated scalp, and it is not a treatment for androgenetic alopecia.

learn Sulforaphane

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.

learn Tea tree

Can tea tree–based topical products support hair growth indirectly by improving scalp conditions linked to hair loss? One 4-week trial found a 5% tea tree oil shampoo reduced mild dandruff, but no study has shown that tea tree products improve hair growth or hair loss. Tea tree oil can cause skin allergy.

learn tamsulosin

Should people experiencing hair loss be concerned about using tamsulosin-based medications? The tamsulosin label does not list hair loss, and no study has found a link, though trials did not measure hair. The label does warn about fainting on standing, rare priapism and eye-surgery complications.
