would not recommend for long straight hair or pets [SEP] brush very very dense too dense to grab anything creates a lot of frizz and static when used on long hair since it only brushes the very surface bristles are unevenly cut definitely not long straight hair tried it on my dog just smoothens the top still doesn t get rid of any tangles still creates a lot of static smells bad tried washing it a few times and still smells bad tried spraying on other scents and the boar smell is very overpowering and makes hair smell that way too
