research Reduction mechanism of L ‐cysteine on keratin fibers using microspectrophotometry and Raman spectroscopy
L-cysteine slows down the breaking of bonds in hair due to electrostatic interactions.
research Diffusion behavior of poly(ethylene imine) into keratin fibers using microspectrophotometry
PEI diffuses into hair at a constant rate, and urea speeds up this process.
research Chemical and photo-oxidative hair damage studied by dye diffusion and electrophoresis.
Chemical treatments and light exposure damage hair proteins.
research Photodegradation of human hair: a microscopy study
UV radiation significantly damages hair, especially with humidity, making it more vulnerable to further damage.
research Photodegradation of hair of different ethnicity after 1 year of exposure to natural weathering in Arizona

5 / 1000+ resultscommunity 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 This tells you if you're shedding or losing hair (along with other things like fibrosis)
High frequency ultrasonography and HR-MRI can help identify hair shedding causes like inflammation and fibrosis. The conversation discusses the potential of using these technologies to evaluate treatments like Verteporfin for hair regeneration.
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 📈 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 [HELP!] TOPICAL FINASTERIDE BLOOD TEST DONE! [0.025% vs 0.015%]
User experienced good results with topical finasteride, noting reduced DHT and increased testosterone. They plan to revert to a lower dosage after observing slight libido reduction.
