    TLDR New resin B makes artificial hair fibers hold curls longer than traditional resin A.
    The study from 2007 evaluated the curl durability of artificial hair fibers, specifically comparing traditional resin A (ABS-based) with new resin B (styrene-based) in a 70:30 weight ratio. The fibers were produced using a twin-screw extruder and then drawn to create wig fibers. Durability was tested by heat setting the fibers on rods of different diameters and measuring curl elongation over time, with a 15% elongation marking the end of the curl's lifespan. The results showed that fibers with resin B had better curl durability, particularly for smaller curls (18mm diameter), and maintained less than 15% deformation after 2160 hours for larger curls. Accelerated life testing at 50°C and 60% relative humidity supported these findings, indicating that the improved durability of the PVC/B fibers was due to their enhanced heat resistance and lower density.

      The conversation discusses various treatments for hair loss, including finasteride, minoxidil, dutasteride, microneedling, and checking for nutrient deficiencies. Some users suggest adding hydrocortisone butyrate, low-dose progesterone, or tretinoin to treatment regimens, while others recommend cosmetic solutions like Toppik hair fibers or shaving the head.

      Minoxidil with alcohol and propylene glycol was more effective than non-alcohol versions, and RU58841 worked best in a non-water-based solution. Oral finasteride showed better results than topical, despite side effects; microneedling and tretinoin worsened hair loss, and PRP was only helpful when younger.

      The conversation is about hair transplants and the perception that they often look unnatural, especially in the first few rows of hair. There is a debate about whether it's better to choose a cheaper clinic in Turkey or a more expensive one in the USA, with some arguing that experience and skill matter more than cost.
