Review (3/5): Does not feel like it can straighten hair at the roots but love the low heating temp.
I have tried a number of these brushes. What I like about this one is that it goes down to 80C (176F). It was so cool that I was not sure it was on. I have fine hair, high porosity that is 5 months post-straightening relaxer. And, I find that light heat with a silicone-based glosser helps to gently close the cuticle and to keep my roots from tangling. What I don’t like is that this brush design does not have the round guiding bristles around the edges that help to pull your hair into the hearing plate. So, it feels like you are brushing your hair with your elbow and that it is not penetrating to the roots. You have to grip the hair with your other hand so it feels like you are only getting the shaft of your hair. So, the brush is best for people with longer hair who do not have curly roots or those who need the super low heat setting as an option.
If you would like to be able to rake the brush over your roots to tame curls at 250 F and up, other bushes to consider are https://www.amazon.com/gp/product/B07FGV9NQG/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&th=1 or https://www.amazon.com/gp/product/B071HFQGJX/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1. Note - My glamfields brush malfunctioned after first use which is why I ended up trying this one, but I decided to give Glamfields another chance because it is great when it works - never had results like that before. The BuTure mini is like the Glamfields brush but smaller. Both feel better (more like a real brushZ) than this one.
