The Perfect Hair Health web app is an excellent educational resource. I've used it to learn about how hair works, available treatments, and product information. It's refreshing to have access to insights based on reviewed research, especially given the number of questionable products often promoted by the health and wellness community. This site has become my go-to resource and a defense against misleading marketing and influencers. The "Compare Treatments" feature is the most informative and innovative tool I've found on my journey to better hair health. Thanks to Rob and the team for their hard work!
