    TLDR Hair texture changes with age due to varying levels of lipids.
    The study used argon sputter etching-scanning electron microscopy (ASE-SEM) to visualize hair lipid images, revealing convex structures with a stitch pattern (SP) at the cell membrane complex (CMC). Hair fibers from 27 Japanese females showed significant positive correlations between SP scores (Types 0 to 4) and levels of exogenous lipids, indicating that these lipids predominantly form the convex SP. Observations of 380 hair fibers from Japanese, German, and American females aged 3 to 77 years demonstrated similar age-related changes in lipid images, with exogenous lipid levels increasing and then decreasing with age. This suggests that age-related changes in sebum excretion affect hair texture.

      A rigorous and extensive regimen for hair regrowth, including oral and topical minoxidil, finasteride, dutasteride, RU58841, various oils, supplements, and lifestyle changes, is discussed with skepticism and humor. The consensus is that such an extreme routine is impractical and potentially harmful, with no guaranteed results.

      A user is experiencing increased hair shedding after using castor oil and rosemary oil twice a week for two months. They are concerned whether this is normal or if the castor oil's thickness is causing hair loss.
