research The science of color: How chemical dyeing processes transform hair structure

November 2025 in “Zenodo (CERN European Organization for Nuclear Research)”

This study examined how different hair dye processes affect hair structure at a molecular level, finding that oxidative dyes increase keratin porosity more than non-oxidative dyes, and highlighted emerging technology aimed at reducing hair damage while preserving color quality.

research The science of color: How chemical dyeing processes transform hair structure

November 2025 in “International Journal of Science and Research Archive”

This study reviews how different hair dyeing methods affect hair structure, showing oxidative dyes cause more structural damage than semi-permanent dyes, while new technologies aim to minimize harm while preserving color.

research The science of color: How chemical dyeing processes transform hair structure

November 2025 in “Zenodo (CERN European Organization for Nuclear Research)”

In this study, researchers investigated how different hair dye processes affect hair structure, finding that oxidative dyes disrupt hair more than semi-permanent dyes, and emerging technologies could help maintain hair health while achieving desired color.

research CHEMICAL ASPECTS OF HAIR LOSS AND ITS COSMETOLOGICAL SIGNIFICANCE

4 citations , March 1975 in “British Journal of Dermatology”

This article examines the chemical factors contributing to hair loss and their significance in cosmetology but does not report new empirical results.

research Chemical Safety and Technical Decision-Making in Hair Procedures: A Professional and Scientific Perspective

community 12 months of diffuse shedding on fin, unsure how to proceed

in Finasteride/Dutasteride 86 upvotes 1 year ago

A user experienced 12 months of hair shedding on finasteride and is unsure about continuing, increasing the dose, or switching to dutasteride. Suggestions include adding minoxidil, adjusting finasteride dosage, and checking for deficiencies.

community The case of a 78 year old man who accidentally regrew his hair (published in the British Medical Journal)

in Chat 213 upvotes 10 months ago

A 78-year-old man regrew hair after suffering burns, suggesting that injury-induced healing processes might trigger hair growth. Microneedling and other treatments like minoxidil and finasteride are discussed as potential methods to stimulate similar regrowth.

community Bimatoprost vs Latanoprost for scalp hair growth

in Treatment 1 upvotes 6 months ago

Bimatoprost and latanoprost are being considered for scalp hair growth, with concerns about side effects like skin darkening and fat loss. A user warns about potential chemical burns from latanoprost.

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.

community if hair follicle miniaturization happens slowly and gradually over a few hair cycles then wouldn't that mean that to regain maximum or top thickness from treatment you would at least need 5-10 years?

in Research/Science 53 upvotes 10 months ago

Hair regrowth from treatments like finasteride, dutasteride, and minoxidil can take several years, with most visible results appearing within 1-2 years and potential improvements continuing up to 10 years. Consistency and patience are crucial for achieving maximum hair thickness, as hair miniaturization and regrowth are gradual processes.
