research Discovery of a Novel Non-invasive AR PROTAC Degrader for the Topical Treatment of Androgenetic Alopecia

December 2024 in “Journal of Medicinal Chemistry”

In this study, researchers discovered a compound called C6 that exhibits excellent skin retention and androgen receptor degradation properties, significantly promoting hair regeneration in a mouse model of androgenetic alopecia following non-invasive topical application, suggesting potential for broader use of PROTACs in treating skin diseases.

research PROTAC Degraders of Androgen Receptor‐Integrated Dissolving Microneedles for Androgenetic Alopecia and Recrudescence Treatment via Single Topical Administration

December 2022 in “Small methods”

This study developed dissolving microneedles incorporating a new AR degrader for treating androgenetic alopecia, showing that a single application leads to superior hair regeneration compared to daily minoxidil, without systemic toxicity or androgen-related issues.

research Next Generation Therapeutics for Androgenetic Alopecia

January 2026 in “OSF Preprints (OSF Preprints)”

In this study, researchers presented a novel therapeutic approach for androgenetic alopecia combining AR-PROTAC degradation with regenerative strategies and evaluated the potential of GT20029 as a topical treatment, proposing a three-phase protocol and future research hypotheses.

research Discovery of an Androgen Receptor Degrader Featuring a Pyridazinyl Glutarimide CRBN-Binding Motif for Transdermal Treatment of Androgenetic Alopecia

May 2026 in “Journal of Medicinal Chemistry”

In this study, the authors developed a novel PROTAC named dAR-6–1, which demonstrated superior hair regeneration in an AGA mouse model compared to minoxidil, highlighting its promise as a therapy due to potent AR degradation and excellent skin permeability.

community AH-001 another topical AR degrader beside GT20029, completed Phase I

8 upvotes 10 months ago

AH-001 is a new topical treatment designed to degrade androgen receptors, targeting the root cause of androgenetic alopecia without the side effects of oral treatments like finasteride. It has shown a strong safety profile and good local tolerability in early trials.

community My Hair Loss Protocol - Actually works!!!

14 upvotes 1 month ago

A 22-year-old man experienced significant hair regrowth using a combination of biotin supplements, Hims topical finasteride + minoxidil solution, a microneedling pen, 0.5 mg dutasteride, and topical PP405 solution. Despite skepticism about PP405's effectiveness, he claims this regimen worked for him after previous treatments failed.

community 1 Year Progress - protocol in description :)

in Progress Pictures 233 upvotes 7 months ago

The user started using 1mg oral finasteride a year ago and added oral minoxidil 3-4 months ago, experiencing no side effects except initial aching. They found oral minoxidil more effective for regrowth and easier than topical due to its toxicity to dogs.

community Desensitize Follicle Sensitivity to DHT?

12 upvotes 1 month ago

Hair follicles cannot be desensitized to DHT like allergies; treatments focus on reducing DHT levels or blocking its effects using methods like finasteride, GT20029, or PROTACs. Topical treatments like ceterizine and BPA application are also mentioned.

community Thoughts on my Topical and Oral concept idea ?

1 upvotes 2 years ago

The user is seeking advice on improving their hair loss treatment regimen, considering changes to their topical solution, and is curious about others' daily routines and recommendations for medications and supplements. They are contemplating switching Tretinoin for Tazarotene, Latanoprost for Bimatoprost, and possibly adding Alfatradiol, Topical Melatonin, or a topical androgen receptor antagonist.
