As their name implies, flat brushes are any hair brush that has a side sans bristles and can lie flat on a table or vanity. Flat brushes come in rectangular and oval shapes, or even ergonomically shaped options, like Crave Naturals' Glide Thru Detangler. Paddle brushes are typically larger flat brushes that often have a squishy cushion under the bristles. In contrast, vented flat brushes have openings between each row of bristles, which can be helpful when using a blow dryer. 

Flat brushes, particularly paddle brushes, are detangling powerhouses. Besides untwisting jumbled strands, flat brushes also tame static.This versatile brush type is a go-to choice for people with long hair or thick hair. To enhance your hair's natural shine, consider a flat brush with boar bristles. Besides massaging and stimulating your scalp, these natural bristles surpass synthetic bristles by dispersing oil all through your hair. And if detangling freshly washed hair is your aim, opt for a flat brush specifically designed for this task, like a wet brush, to avoid breakage.

When it comes to styling, paddle brushes are a perfect choice for maintaining straight hairstyles. If your hair is naturally straight, you can rely on a paddle brush to smooth any wayward strands. These brushes can also help get you through your morning routine faster. "On shoulder length or longer hair, it can expedite drying time, as it spreads the hair across the brush," hairstylist Kim Becker explained to Women's Health.
