Brushing your hair is actually terrible for it.
Tell you what: lean over your sink, and brush your hair right over it. When you’re done, you’ll notice lots of pieces of hair and even full length strands laying in the sink. The reason? Brushing your hair breaks the weaker strands, and is the main cause for split ends.
I have heard lots of beauticians advise their clients to brush their hair with a round brush to bring down the oil that is close to the scalp all the way to the ends. By the time your brush reaches the ends of your hair, there’s no oil left on it, so if you want to add oil or moisturize the tips of your hair, simply apply an oil treatment, but do not brush it!
If you still feel the urge to use a brush, then so be it, but keep in mind that the only time to brush your hair is right after you wash your hair and put plenty of conditioner in it, and you should only do so with a flat brush with bristles that are at least 1/3 of a inch apart. In other words: never brush your hair while it’s dry.
