Does anyone know the best brush for thick hair?

Hi! I run an e-commerce site on shared hosting and I’m looking to promote hair care products, particularly high-end hair brushes. So I’ve been testing out just about everything to write credible product descriptions, and the question of the best brush for thick, curly hair keeps popping up in my Google Search Console stats—it’s one of the queries that drives the most organic traffic to my pages.
Personally, I’ve tried two or three models sent directly by my suppliers, and honestly, there’s a real difference between low-cost brushes and the higher-end ones. But I’m wondering if you have any feedback on how to structure category pages around this kind of ultra-competitive keyword it could help optimize the site’s architecture. Any thoughts?
