for straight easy to manage hair only [SEP] i should had read the other reviews before buying the bristles were not even glued in they fell out while i was brushing my hair at first i thought i broke it until i checked the other brush and it came out with ease these brushes are only good for those with fine thin hair not thick or curly so if you have unmanageable hair like i do i do not recommend you buy these brushes they are great for my cat and dog though they love them
