I've been Bass dual-bristle hairbrushes literally my entire life. My mom always said they were the best, so I always just bought the same brand whenever I lost a hairbrush or a new puppy chewed one up.Then came Amazon with all it's cheap Chinese sellers, and I thought I would save a few bucks. Well, folks, you get what you pay for. The cheap generic brush shed boar bristles immediately and the nylon ones were so bendable that they offered no additional detangling. They also pulled right out when I would try to clean the brush. I was honestly relieved when my foster dog chewed it up and I could buy a new one.Back to Bass. The nylon bristles are pleasantly medium firm, enough to work through thick hair and give you a good scalp massage, but not so firm they will pull and break the hair. These brushes are also made to last--you won't need to buy a new one unless you lose it. I've had some of mine for a decade.Other reviewers are correct that the tips come off the nylon brushes in the course of use. Personally, no one in my household minds this and we do not find the untipped bristles painful. My itchy husband actually views this as a bonus--he uses his as a backscratcher. The best backscratcher, according to him. In a nutshell: a great dual bristle brush with a dual purpose, lol.
