research Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties

May 2026 in “International Journal of Cosmetic Science”

This study found that UV radiation exposure during a simulated Brazilian summer caused more significant mechanical damage to natural hair than bleaching, although both caused comparable structural alterations, with double bleaching leading to the most severe protein degradation.

research Measuring oxidative damage to human hair from solar radiation and pollution: A critical review

May 2026 in “Journal of Photochemistry and Photobiology”

This review found that solar radiation, pollution, and trace metals cause significant damage to human hair, with factors like UVB radiation primarily affecting light-colored and bleached hair; most data were derived from in vitro and ex vivo simulations.

research Improving the Mechanical Properties of Damaged Hair Using Low-Molecular Weight Hyaluronate

1 citations , November 2022 in “Molecules/Molecules online/Molecules annual”

This study found that low-molecular-weight hyaluronate significantly improved the mechanical strength and elastic modulus of overbleached hair by enhancing hydrogen bond networks within keratin.

research Optical evaluation of internal damage to human hair based on second near‐infrared window polarization microscopy

May 2024 in “International Journal of Cosmetic Science”

This study found that using near-infrared optics, specifically in the second NIR window, allows for effective noninvasive evaluation of intra-hair damage caused by cosmetic treatments, demonstrating distinct damage types and changes in hair condition due to chemical or thermal processes.

Characterization of the Mechanical Properties of the Cortex Region of Human Hair Fibers by Multiparametric Atomic Force Microscopy Mapping

research Characterization of the mechanical properties of the cortex region of human hair fibers by multiparametric Atomic Force Microscopy mapping

May 2024 in “Ultramicroscopy”

Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.

community Dutasteride made my hair curlier

518 upvotes 3 months ago

Dutasteride improved hair curliness and was preferred over finasteride due to fewer side effects. The user switched from finasteride to dutasteride, taking 0.5mg daily for 6 months.

community Inflammation's surprising role in shrinking hair follicles and AGA

in Technology 66 upvotes 4 months ago

Inflammation plays a significant role in hair follicle miniaturization and androgenetic alopecia, with treatments like ketoconazole shampoo, minoxidil, and finasteride being used to address it. Users discuss the benefits of anti-inflammatory treatments and peptides like KPV, alongside traditional hair loss treatments, to improve scalp health and hair quality.

community My Theory Of Androgenic Alopecia

16 upvotes 9 months ago

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

community 3,5 months of only topical minoxidil

776 upvotes 9 months ago

A 24-year-old reported new hair growth on temples after 3.5 months of using topical minoxidil without shedding. They plan to add finasteride to maintain progress, as minoxidil alone may not be enough long-term.

community Anyone have any experience with these SoCal Hair Surgeons?

8 upvotes 1 month ago

The conversation discusses choosing a hair transplant surgeon in Southern California, with mentions of Dr. Ken Williams, Dr. Varona, Dr. Sean Behnam, Dr. Amir Yazdan, and Dr. Nader. Users share experiences with various surgeons, including positive feedback for Dr. Cortez in Tijuana and Dr. Behnam, while expressing concerns about Dr. Varona's results and Dr. Yazdan's past complaint.
