In general, you should never brush for wavy hair. The general consensus is that pulling a hairbrush throughout the wavy hair can damage your curl structure and create a frizzy mess. So instead of detangling the hair with your fingers or comb, you should only use your hairbrush just right before washing your hair.  Another important fact is that brushing your hair when wet can respond to breakage as the hair is weaker while it is wet. In wet brushing, your wavy hair will also damage the curly form, and some folks will find the wavy hair can be more curly or lifeless when it dies. However, other people will find the hair dries into nice beach waves though it won't be curly without brushing.  Caring correctly for wavy hair needs a lot of trial and error. And some performance is indeed better for you, which may not work better for someone else. So, we suggest experimenting with brushing the wavy hair when it is wet and seeing what performance it does for you. Hairbrushes are very useful for detangling, even though they can make your wavy hair frizzier. We recommend using a detangling brush like Tangle Teezer before taking your shower. They are amazingly gentle and let you brush your hair before washing it with minimal breakage.
