The Effect of Different Concentrations of All-Trans Retinoic Acid on the Growth and Survival of Mouse Hair Follicle Stem Cells

Adipose-derived stem cells with ATP improved hair regrowth in male and female mice with androgenetic alopecia. The most effective treatments were low dose stem cells with ATP for males and medium dose stem cells with non-liposomal ATP for females.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

Ritlecitinib and PP405 show promise for hair regrowth. Diagnosing the cause of hair loss is crucial before treatment.

Topical retinol does not affect hair loss and may help hair regrowth. It is different from isotretinoin, which can cause hair loss due to its systemic effects.

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.

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.
