What type of brush is commonly used for detangling hair after washing?

A wide-tooth comb is commonly used for detangling hair after washing because its design allows it to gently glide through wet hair without causing excessive breakage or damage. Wet hair is more vulnerable and prone to tangles, so a wide-tooth comb, with its spaced-out teeth, helps to minimize snagging. This type of comb can efficiently work through knots and tangles while maintaining the hair's integrity, making it an excellent choice for post-wash detangling.

In contrast, a round brush is typically used for styling and adding volume to dry hair rather than for detangling. A vent brush, while suitable for quick drying and some styling techniques, can pull and tug at wet hair, which may lead to breakage. A boar bristle brush is great for distributing natural oils and smoothing the cuticle of dry hair but is not ideal for detangling, especially when hair is wet. Thus, the wide-tooth comb stands out as the most effective tool for this specific task.
