Round brush - round brush are ideal for creating that volume and body in your hair. This is the brush you want to use when you are blow-drying your hair. Small-sized brushes create tighter curls, while brushes with larger barrels are known to straighten hair and create subtle waves.

A curved brush - if your lashes are straighter than uncooked spaghetti, a curved wand will hug your lashes from the root to the tip, curling your lashes as you coat them. For a curl that really lasts, start with an eyelash curler and opt for a water-proof formula to prevent the dreaded 'droopage'.
Teasing brush- this can be done to produce hairstyles such as a bouffant or a beehive, or just to add volume and size to a plainer hairstyle. A teasing brush is used instead of a comb when hair is delicate and might be more easily damaged by a comb; the bristles of the brush are less likely to pull as hard on the hair.
Nylon bristle brush - they are often stiffer than boar bristles. Use a nylon bristle brush to penetrate thick hair and to detangle it. Boar bristles are usually softer than nylon. Use a boar bristle brush on fine, thin or damaged hair and for brushing out a style to create a fuller look.
