Pinkie, the First Viable Germline Hypomorph Allele of Retinoid X Receptor Alpha, Reveals an Important Role for RXRα in Th2 Development

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.

Tazarotene shows potential as a standalone treatment for hair regrowth by stimulating new hair follicle formation and promoting angiogenesis, similar to microneedling effects. It can be used topically without minoxidil, but users should start with a low concentration to avoid irritation.

The conversation discusses the mechanism of action of alfatradiol (17 alpha estradiol) in treating hair loss. It explores theories that it either inhibits 5 alpha reductase to prevent T->DHT conversion or aromatizes scalp T into 17-alpha-estradiol to save hair.

The conversation discusses a hair loss treatment regimen including finasteride, minoxidil, micro needling, and oil blends. It questions the addition of retinol, with feedback suggesting tretinoin is more effective, while retinol may cause hair loss.

Switching from tretinoin to tazarotene with minoxidil led to new hair regrowth after years of maintenance. Tazarotene's selectivity and higher concentration might be more effective for hair growth.

KX-826 Phase II results show that a 0.5% concentration performs better than 1% for treating male pattern baldness. Concerns about receptor upregulation from long-term DHT antagonism were mentioned.
