research Impact of oxidative hair coloring and bleaching on hair fiber properties

May 2026 in “Brazilian Journal of Hair Health”

This study found that bleaching significantly damages hair structure and increases combing difficulty, while dyeing with emulsifiers can partially reduce damage and improve combability, yet both processes cause notable protein loss.

research Improve the physical and chemical properties of camel's hair fiber in Afif province: تحسين الخصائص الفيزيائية والكيميائية لشعيرات وبر الإبل بمحافظة عفيف

September 2019 in “Mağallaẗ al-ʿulūm al-ṭabīʿiyyaẗ wa-al-ḥayātiyyaẗ wa-al-taṭbīqiyyaẗ”

This study found that camel hair from Afif has suitable physical and chemical properties for textile production and its characteristics can be enhanced with chemical additives like acetic acid.

research Evaluation of Hair Fiber and Sensory Properties following the Application of Conditioners containing Jojoba and Coconut Oils

January 2026 in “Brazilian Journal of Pharmaceutical Sciences”

This study assessed the effects of chemical treatments on hair fiber integrity and found that conditioners with vegetable oils like jojoba and coconut enhanced hydrophobicity and reduced combing friction except for jojoba, while participants preferred these oil-containing conditioners over the base formulation.

research Single hair fiber assessment techniques to discriminate between mineral oil and coconut oil effect on hair physical properties

3 citations , September 2020 in “Journal of cosmetic dermatology”

This study found that coconut oil significantly increased the tensile strength of twisted hair fibers due to its ability to penetrate the hair core, in contrast to mineral oil.

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.

129 upvotes 3 years ago

The "Big 3 Stack" for hair loss treatment, which includes Minoxidil for hair density improvement, Ketoconazole shampoo for enhancing hair volume and thickness, and Finasteride for blocking hair loss causing hormones. Microneedling can boost Minoxidil's effects.

community Are fruit seeds more effective than fin/Dut?

7 months ago

The user experienced reduced hair loss after switching from finasteride and dutasteride to consuming fruit seeds like pumpkin and flaxseed, but others suggest the improvement is likely due to the delayed effects of the medications. There is skepticism about the seeds' effectiveness in blocking DHT compared to the medications.

community The mechanism of androgenic alopecia

36 upvotes 11 months ago

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

community Is there a topical androgen receptor blocker so we don't have to fuck with the enzyme and destroy our allopregnanolone, but go and hit the end target straight?

in Treatment 44 upvotes 2 years ago

The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.

Do hair fibers wash out easily, or do you need a special shampoo to remove them? There is no published trial comparing shampoos for removing hair fibers. Because the fibers cling by static rather than bonding chemically, and because users consistently report they rinse out with ordinary shampoo, the specialist fiber-removal shampoos do not appear to be necessary; a clarifying shampoo may help when fibers are layered under hairspray or gel.
