research Dyeing regions of oxidative hair dyes in human hair investigated by nanoscale secondary ion mass spectrometry

25 citations , January 2013 in “Colloids and surfaces. B, Biointerfaces”

This study found that melanin granules in black human hair are key dyeing regions for oxidative hair coloring, as confirmed by nanoscale mass spectrometry analysis detecting deuterium ions.

research Acetyl zingerone methyl ether protects hair against oxidative damage incurred during and after treatment with permanent dyes and helps extend longevity of newly developed hair colour

August 2024 in “International Journal of Cosmetic Science”

This study found that acetyl zingerone methyl ether (MAZ) in hair dyes and haircare products may reduce oxidative damage, improve hair condition, and enhance the longevity and quality of dyed hair color.

research Long-term toxicity studies on oxidation hair dyes

79 citations , January 1975 in “Food and Cosmetics Toxicology”

In this study, oxidation hair dye formulations tested on mice showed no evidence of causing systemic toxicity or cancer over an 18-month period.

research Protective effects of Ecklonia cava extract on the toxicity and oxidative stress induced by hair dye in in-vitro and in-vivo models

5 citations , February 2019 in “Journal of oceanology and limnology (Online)”

This study found that adding 7% Ecklonia cava extract to oxidative hair dyes significantly reduced their cytotoxicity and oxidative stress without affecting color performance.

research Percutaneous penetration of hair dyes

66 citations , February 1985 in “Archives of dermatological research”

community NMN Promotes Cell Proliferation and Hair Growth by Reducing Oxidative Stress

14 upvotes 2 years ago

NMN shows promise in promoting hair growth by reducing oxidative stress and weakening androgens. It may be a beneficial addition to hair loss treatments like Minoxidil and Finasteride.

community Is 2-deoxy-D-ribose (2dDR) good for human hair?

8 upvotes 2 years ago

Topical 2-deoxy-D-ribose (2dDR) regrows hair in mice almost as well as 2% Minoxidil. However, 2dDR may contribute to oxidative stress and hair loss due to the formation of advanced glycation end products (AGEs).

community The Role of Astaxanthin as a Nutraceutical in Health, Age-Related Conditions and Hair Loss

3 upvotes 3 years ago

Astaxanthin (ASX) is highlighted as a promising supplement for treating hair loss due to its antioxidant properties. It may help with inflammation and oxidative stress, which are linked to hair loss and aging.

community Finasteride solution changing colors

in Finasteride/Dutasteride 1 upvotes 5 months ago

A user noticed a color change in their hair loss solution containing minoxidil, finasteride, retinoic acid, and hydrocortisone after storing it for several months. They are concerned about the effectiveness of the solution due to potential oxidation.

community Does anyone know the chemical formula for pelage pp405?

15 upvotes 1 year ago

The conversation discusses the lack of public information on the chemical structure of PP405, a hair loss treatment, and the challenges of synthesizing it without a patent. It also explores a patent related to hydrogen-based topical formulations for reducing oxidative stress and inflammation.
