TLDR Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.
The study investigated the three-dimensional architecture of macrofibrils in the human scalp hair cortex, revealing that human hair macrofibrils have a consistent matrix fraction and typically exhibit a double-twist architecture. Unlike wool, human hair showed significant inter-macrofibril variation in the incremental angle increase between intermediate filaments (IFs), with a negative correlation between macrofibril size and IF increment. This variation was observed across different hair types, including Caucasian, Japanese, and African, indicating a common feature in human hair. The findings advanced the understanding of the nano-level and cell-level organization of human hair, highlighting the complexity and variability of macrofibril architecture compared to wool.
MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.
Hair fibers effectively cover thin hair areas, boosting confidence and reducing stress about hair appearance. Users discuss combining hair fibers with other products like hair spray, dermmatch, and Boldify, noting challenges like blocking minoxidil absorption and the importance of color matching.
A user plans to experiment with creating new hair follicles using methods like derma rolling, applying lithium chloride, tannic acid, and various other substances including caffeine, ketoconazole, and raspberry ketones. They also consider using anti-inflammatories, immunosuppressants, and DHT inhibitors to potentially improve results.
MCL-1 is important for hair follicle stem cell survival, but its impact on humanhair regrowth is unclear. Minoxidil and finasteride are the main treatments, with doubts about new discoveries leading to effective human solutions soon.
