How should I brush wavy hair (when i brush it with a normal brush it gets big)?

To brush wavy hair without causing frizz or volume, use a wide-tooth comb or a brush specifically designed for wavy or curly hair. Start detangling from the ends and work your way up to the roots to minimize breakage. It's best to brush your hair when it's damp and coated with a leave-in conditioner or detangling spray to make the process easier and reduce frizz. Additionally, consider scrunching your hair gently after brushing to maintain your waves.
