TLDR A new treatment plan for hair loss combines targeted therapies and regenerative strategies to stabilize, reverse, and maintain hair growth.
This paper introduces a comprehensive therapeutic framework for androgenetic alopecia (AGA) that combines PROTAC-mediated androgen receptor (AR) degradation with regenerative and micro-environmental strategies. It highlights GT20029 as a topical AR-PROTAC and compares AR degradation with antagonism. The study also explores early-intervention models based on genetic predisposition and pre-miniaturization biomarkers. The framework integrates stem-cell biology, dermal papilla senescence, perifollicular fibrosis, and niche-engineering into a three-phase protocol: stabilization, reversal, and maintenance. Additionally, it proposes a development timeline for therapies and testable hypotheses to guide future research and clinical applications in AGA.
