research An ex vivo study of the effects of co-surfactants and conditioning additives on hair colour protection

January 2014 in “University of the Arts London Research Online (University of the Arts London)”

Certain ingredients can help protect hair color.

research In vivo and in vitro effect of novel 4,16-pregnadiene-6,20-dione derivatives, as 5α-reductase inhibitors

27 citations , July 2008 in “The Journal of Steroid Biochemistry and Molecular Biology”

The new compounds may be more effective and cheaper than current treatments for conditions like baldness.

research In Vivo and In Vitro Evaluation of PTeCA (1H‐Pyrrole‐2,3,4,5‐Tetracarboxylic Acid) in Hair Matrix as a Marker for Oxidative Cosmetic Treatment

March 2026 in “Drug Testing and Analysis”

This study observed that the degradation product PTeCA significantly increased in hair treated with oxidative cosmetics, suggesting it could be a reliable marker for detecting such treatments, with a proposed PTCA cut-off value using PTeCA as the gold standard.

research Enhanced ex vivo skin retention of bicalutamide using a nano-in-micro composite: Drug-loaded lipid vesicles in a dissolving microarray patch

April 2025 in “European Journal of Pharmaceutics and Biopharmaceutics”

This study developed and tested Bicalutamide-loaded lipid vesicles in dissolving microarray patches for topical application, finding that they effectively deliver Bicalutamide through murine skin while maintaining a favorable safety profile, suggesting potential to improve treatments for androgenetic alopecia.

community Theoretically won't this be better than finasteride? Azelaic acid + zinc

9 upvotes 3 years ago

The conversation discusses using zinc sulphate and azelaic acid to inhibit 5 alpha-reductase activity, which could potentially treat androgen-related skin conditions like hair loss. Combining these with vitamin B6 could enhance the effect, potentially offering an alternative to finasteride.

community Amplifica: Hope or Cope? A Review of Their Pipeline

9 upvotes 4 weeks ago

Amplifica's AMP-303 showed a modest increase in hair growth, but results were inconsistent and potentially misleading. Hyaluronic acid and osteopontin are being explored for hair growth, with varying effects on different hair types and conditions.

community Those minoxidil collagen studies

3 upvotes 1 year ago

Minoxidil stimulates hair growth by affecting hair follicle cycles and may inhibit collagen synthesis under certain conditions. The user also mentions using vitamin D and red light therapy as part of their hair loss treatment.

community PP405 Won't Work Long Term: Hair Follicle Damage Due to Abuse of the ISR System

67 upvotes 11 months ago

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.

community Peptides that Stop Hair Loss? | In-depth Literature Review Video

76 upvotes 2 years ago

Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.
