Protection and Restoration of Damaged Hair via a Polyphenol Complex by Promoting Mechanical Strength, Antistatic, and Ultraviolet Protection Properties

research Protection and Restoration of Damaged Hair via a Polyphenol Complex by Promoting Mechanical Strength, Antistatic, and Ultraviolet Protection Properties

1 citations , July 2023 in “Biomimetics”

This study found that a hair-coating polyphenol complex significantly enhanced the mechanical strength, UV protection, and antistatic properties of damaged hair, suggesting potential benefits for hair treatment.

Production of Ultraviolet-Light-Induced Skin Erythema in the Hairless Rat: A Comparison with the Haired Rat in Screening for Anti-Inflammatory Drugs

research Production of ultraviolet-light-induced skin erythema in the hairless rat: a comparison with the haired rat in screening for anti-inflammatory drugs

3 citations , October 1979 in “Laboratory animals”

This study found that phenylbutazone and fluocinolone acetonide have similar anti-redness effects in both haired and hairless animals, making hairless rats a potential alternative for testing without needing depilation.

research Protection of hair from damage induced by ultraviolet irradiation using tea (Camellia sinensis) extracts

13 citations , August 2021 in “Journal of Cosmetic Dermatology”

This study found that Camellia sinensis (tea) extracts may protect hair from UV-induced damage and color change, with efficacy linked to higher concentrations of key compounds like catechins.

research Extracellular vesicles from adipose-derived stem cells ameliorate ultraviolet B-induced skin photoaging by attenuating reactive oxygen species production and inflammation

90 citations , July 2020 in “Stem Cell Research & Therapy”

This study found that adipose-derived stem cell extracellular vesicles reduced wrinkles and promoted cell proliferation in UVB-induced photoaging in mice by decreasing oxidative stress and inflammation.

research A Novel In Vivo Model for Evaluating Agents that Protect Against Ultraviolet A-induced Photoaging

26 citations , April 1998 in “Journal of Investigative Dermatology”

This study in transgenic mice found that the combination of SPF 15 sunscreen and a UVA filter provided strong protection against UVA-induced elastin promoter activation and thus may reduce photoaging.

community The Health Benefits of Head Hair

in Research/Science 19 upvotes 11 months ago

Hair provides protection against head trauma, reduces skin cancer risk, helps remove heavy metals, and aids in wound healing. The conversation emphasizes the health benefits of maintaining head hair beyond cosmetic reasons.

community Evolution theory: AGA is your body trying to reduce the risk of prostate cancer by exposing your scalp to more UV

in Research/Science 9 months ago

Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.

community What About Phytosterol Alternatives - Rice Bran Oil - Natural DHT Blockers

3 upvotes 2 years ago

The conversation discusses natural DHT blockers like rice bran oil, which may reduce 5α-reductase activity similarly to Minoxidil and Dutasteride. One user argues that finasteride is more reliable and effective than natural alternatives.
