research Fermented grapeseed oil repairs chemically damaged hair via enhanced permeability mechanisms

July 2025 in “Scientific Reports”

This study reported that fermented grapeseed oil may enhance hair permeability and improve strength and color retention in chemically treated hair compared to regular grapeseed or silicone oils.

Preparation and In Vitro Evaluation of Protective Effects of Silibinin-Loaded Polymeric Micelles on Human Hair Against UV-B Radiation

research Preparation and in vitro evaluation of protective effects of Silibinin‐loaded polymeric micelles on human hair against UV‐B radiation

January 2024 in “Journal of cosmetic dermatology”

This study found that Silibinin-loaded polymeric micelles significantly protected human hair from UV-B induced structural and chemical damage by preventing increases in roughness and reducing protein loss.

Preparation and In Vitro Evaluation of Protective Effects of Quercetin-Loaded Solid Lipid Nanoparticles on Human Hair Against UV-B Radiation

research Preparation and In Vitro Evaluation of Protective Effects of Quercetin‐Loaded Solid Lipid Nanoparticles on Human Hair Against UV‐B Radiation

September 2024 in “Journal of Cosmetic Dermatology”

This study found that quercetin-loaded solid lipid nanoparticles demonstrated positive protective effects on human hair against UV-B light, as they controlled microscopic surface roughness, reduced chemical changes, and minimized protein loss in vitro compared to other treatments.

research FFA and Personal Care Product Use: A Systematic Review and Meta-Analysis

November 2022 in “Research Square (Research Square)”

This meta-analysis suggests a significant association between the use of facial sunscreen and moisturizer and frontal fibrosing alopecia, while finding no significant relationship with hair products or treatments.

The conversation discusses regret over delaying finasteride use for hair loss and emphasizes the importance of early preventive measures for health issues, including using sunscreen, taking vitamins, and considering medications like statins. Participants share experiences with finasteride, sunscreen, and other health practices to prevent aging and health problems.

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.

community Comprehensive Microneedling Guide
