For Short Hair

If you have short hair or hair that is about chin length, you need to opt for hair brush sizes that are smaller in diameter. For this brush size, you can also use them to style your bangs.

For Medium Hair

For hair that is up to shoulder length, the ideal brush size is somewhere between 35mm to 45mm in diameter. If you use a brush that is too small, there is a tendency for your hair to get stuck within the bristles.

If you have long hair, or those that reaches the collarbone area, you need to go for brushes with a wider diameter. It will be your secret weapon to achieving beautifully voluminous hair!
