TLDR The bio-based complex effectively repairs and protects chemically damaged hair.

The study evaluates a Bio-Based Crosslinking Complex (BCRC) composed of itaconic acid, arginine, D-panthenol, and polysaccharides from linseed and chia, designed to protect and repair chemically damaged hair, particularly from bleaching. BCRC was tested as both a protective agent in bleaching mixtures and a repair treatment in leave-in conditioners. Results from tests on 50 samples showed significant improvements in mechanical strength, thermal stability, shine, and combability of treated hair compared to untreated hair. BCRC-treated hair exhibited a 19.58% increase in tensile strength, restoring up to 92% of the original strength of virgin hair. These findings suggest BCRC's dual functionality as a promising protective and restorative agent for chemically treated hair.

Topical finasteride results in plasma levels 100 times lower than oral finasteride, potentially reducing systemic side effects. Users report similar efficacy with fewer side effects, suggesting a preference for topical application.

community How Does Exosome Therapy Work for Hair Loss?

in Research/Science 5 upvotes 2 years ago

Exosome hair therapy involves injecting stem cell-derived exosomes into the scalp to boost hair follicle regeneration and repair. Exosomes, which are not stem cells but products of them, contain bioactive chemicals and specific growth factors that promote new blood vessel formation, increase cell proliferation, reduce inflammation, and improve tissue repair, all crucial for hair health.
