    TLDR Panthenol is more effective than hydrolyzed protein at improving hair roughness and reducing breakage.
    In 2009, a study was conducted by Youn Duk Kim, Hye Jin Hyun, Ji Hae Lee, Youn Suk Oh, Long Quan Pi, and Won Soo Lee to compare the hair shaft repairing efficacy between panthenol and hydrolyzed protein. The study found that both panthenol and hydrolyzed protein were effective in repairing damaged hair shafts. However, panthenol showed a higher efficacy in improving hair shaft roughness and reducing hair breakage compared to hydrolyzed protein. This suggests that panthenol could be a more effective ingredient for hair care products aimed at repairing damaged hair.

      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.
