5 / 1000+ resultsresearch Cuticular damage to African–American hair during relaxer treatments – A microfluorometric and SEM Study
Relaxer treatments damage African–American hair, with commercial products causing more harm than lab-made solutions.
research Quantifying Polymer Deposition on Hair Fibers by Microfluorometry
Microfluorometry effectively measures how much polymer coats and penetrates hair, useful for evaluating hair products.
research Photodegradation of human hair: a microscopy study
UV radiation significantly damages hair, especially with humidity, making it more vulnerable to further damage.
research Abstracts: Reduction‐induced surface modification of human hair
Chemical treatments change hair surface properties, making it more hydrophilic and able to bind conditioners.

5 / 1000+ resultscommunity Napkin math: are we using 100x more topical finasteride than necessary?
Topical finasteride concentrations are likely much higher than necessary for effective follicular DHT suppression, with current standards being 100-1000 times above the theoretical minimum. Lower concentrations (0.001-0.0025%) might still work locally while minimizing systemic exposure.
community trichoscopy: for those of you with microscopes
The conversation discusses using USB microscopes for scalp photos and provides a link to an overview of trichoscopy. Treatments mentioned include Minoxidil, finasteride, and RU58841.
community 📈 Solving for very low dose topical finasteride titration intervals
The conversation discusses using very low dose topical finasteride to achieve specific serum DHT reduction percentages. It concludes that finasteride dosage increases linearly between 5-30% DHT reduction but requires exponential increases for reductions up to 70%.
community Highly recommend buying a microscope (see pictures)
A user recommends using a microscope to assess hair density and track hair loss progress, finding it useful for evaluating treatment effectiveness, particularly with dutasteride and minoxidil. They advise against obsessing over hair loss and emphasize focusing on other meaningful life aspects.
community Microneeeling Question for Oral Minoxidil
Microneedling can still be beneficial when using oral finasteride and minoxidil, with a recommended needle length of 0.5mm to 1.0mm. A stamp or pen is preferred over a roller for microneedling.
