In this study, the researchers conducted tensile tests on individual curly human hair fibers sourced from a female donor and found distinct mechanical properties under various conditions, including different strain rates and temperatures, both dry and in saline immersion.
research Hair Mechanical Properties Depending On Age And Origin
This research describes methods to analyze the mechanical properties and fracture characteristics of hair across different types and ages, using specialized tensile testing and imaging techniques, without reporting new results.
research Understanding Curly Hair Mechanics: Fiber Strength
This study found that the tensile strength of curly hair is influenced by two main components, with springiness (toe region) contributing significantly, unlike in noncurly hair where it is negligible.
research Quantifying hair shape and hair damage induced during reshaping of hair.
This article reviews various methods and introduces new imaging technologies to assess the effects of hair shaping treatments on hair chemistry and structural integrity, without reporting clinical results.

5 / 109 resultscommunity Crazy idea: creatine + topical finasteride
Using topical finasteride with creatine might help reduce hair loss by targeting local DHT while maintaining normal systemic levels, but results are uncertain without testing. Users report mixed experiences with topical treatments like finasteride, dutasteride, RU58841, and minoxidil, with some seeing regrowth and others experiencing side effects.
community My hair stopped shedding as much in the shower and I traced it back to one change
Switching from a clarifying shampoo to a gentler rosemary biotin shampoo bar reduced hair shedding. Aggressive cleansers can cause scalp inflammation, contributing to hair loss.
community Welp - pp405 conference showed nothing
PP405 shows potential for hair growth by increasing terminal hair and converting vellus hairs, but results are modest and more waiting is needed. It complements existing treatments like minoxidil and finasteride, but won't replace them.
community PP405: Regrows Hair In 8 Weeks. Is This The Miracle Cure?
PP405 is considered as a potential hair regrowth treatment, but users are skeptical due to past product failures. They compare it to Minoxidil and Finasteride, questioning its effectiveness and the intentions of pharmaceutical companies.
community Baldness Breakthrough: microRNA Stimulates Hair Growth in Aging Follicles
miR-205, a tiny RNA, can stimulate hair growth by softening aging hair follicle stem cells in mice. Future tests aim to see if this can work in humans.
