Comprehensive Overview of Rheumatology Studies: Ottawa, Ontario, Canada, February 13–16, 2013

Minoxidil may not be effective due to low sulfotransferase activity, and the user considers adding tretinoin to the regimen. They are unsure about the timing and combination with microneedling.

An arthritis drug, baricitinib, is discussed as a potential treatment for autoimmune alopecia, not androgenetic alopecia. Ritlecitinib is also mentioned as a possible treatment for scarring alopecia.

Tazarotene may be more effective than tretinoin when combined with topical minoxidil for hair loss due to its selective binding to RAR-beta and gamma, though it can cause irritation. Tazarotene's potency can lead to indirect inflammatory reactions despite potentially causing less irritation than tretinoin.

Low Dose Naltrexone (LDN) may reduce inflammation in alopecia conditions. It is discussed as a potential adjunct treatment with finasteride or dutasteride for androgenic alopecia.

Tazarotene may outperform tretinoin for hairline treatment with minoxidil, but lacks evidence. Tretinoin is recommended for the scalp, while tazarotene can be used on the face.

The conversation discusses the potential of new hair loss treatments, with a focus on pyrilutamide, gt20029, and topical alfatradiol, and the possibility of improving their effectiveness through methods like increased concentration and microneedling. Dutasteride is also mentioned as a stronger option.
