This paper reviews chemical analysis methods for trace elements in human hair and supports a no-wash policy due to challenges in distinguishing between endogenous and exogenous element sources.
In this study, researchers developed an environmentally friendly hair coating from casein proteins and tannic acid, enhancing the tensile strength of virgin Asian hair by approximately 21% compared to untreated hair, while maintaining elasticity.

This review suggests that standardized herbal shampoos may offer a safe and sustainable alternative to synthetic products due to their natural saponins and multifunctional benefits, though challenges in consistency and shelf-life persist.
Hair growth relies on mechanical forces, not just chemicals, with tissue acting like a motor. Minoxidil and finasteride help, but maintaining tissue elasticity and addressing mechanical issues are essential.
The conversation discusses the potential of PP405 as a hair loss treatment, with some users expressing skepticism and others hopeful about its development. There is also mention of other treatments like Minoxidil, Finasteride, and Pyrilutamide, with users debating the effectiveness and safety of self-experimentation versus waiting for clinical trial results.
The conversation discusses the synthesis and potential use of JXL069 and PP405 for hair loss treatment, with skepticism about their effectiveness and concerns about safety. Users mention that JXL069 has shown no results in hair growth, and there is confusion about its identity and effectiveness compared to PP405.
Most scalp serums are ineffective for hair loss, with Nécessaire’s “The Scalp Serum” being the only one showing noticeable results, though it's not worth the cost. For androgenetic alopecia, clinical treatments like minoxidil and finasteride are necessary, while caffeine and capixyl may offer some benefits.
OP is considering making a 5% topical Clascoterone (Breezula) for hair loss, as they use Minoxidil but can't use Finasteride due to side effects. They seek advice on creating the topical safely, possibly with help from a trained chemist.
Hair transplantation moves DHT-resistant follicles from a donor area (back and sides of the scalp) into thinning or bald areas. The transplanted hair is generally permanent, though surrounding native hair can keep thinning.
