Prolactin Delays Hair Regrowth in Mice

A new drug targeting prolactin is being discussed for hair regrowth, but skepticism remains as many still rely on minoxidil and finasteride. Concerns include the drug's effectiveness compared to existing treatments and whether it works for those already using 5AR inhibitors.

Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.

High prolactin levels may contribute to hair loss, and some users suggest supplements like mucuna pruriens, vitamin B6, vitamin E, L-Tyrosine, L-Theanine, DIM, and Zinc to lower prolactin. Lifestyle changes to increase dopamine, such as reducing screen time and stress, are also recommended.

High prolactin levels can cause hair loss, and finasteride may increase prolactin. Cabergoline or Vitamin B6 might lower prolactin, but combining them with finasteride requires caution.

Hmi115, a prolactin receptor blocker, showed promise for hair growth, but results from Phase 2 trials have not been published. ABS-201, an AI-based analog, is expected to begin trials in December 2025, while commercialization of treatments like PP-405 is anticipated around 2027.

The user is applying topical finasteride with stemoxydine for hair loss and has noticed hair thickening but no regrowth after two months. They also report high SHBG and prolactin levels and a lack of morning erections, even on low doses of medication.
