A wide-tooth comb is the best tool for detangling wet hair because its design allows for gentle maneuvering through knots and tangles without causing excessive pulling or breakage. The wide spaces between the teeth enable it to glide through wet hair more easily, reducing the risk of damage that can occur when using brushes with closer-set bristles. This is particularly important because wet hair is more fragile and susceptible to breakage than dry hair.

In contrast, a boar bristle brush is typically used for smoothing and distributing oils from the scalp through the hair and may not be effective for detangling, especially when the hair is wet. A round brush is generally used for styling and creating volume but is not suitable for detangling, particularly when hair is wet. Lastly, a vent brush, while good for reducing drying time and adding volume, is not specifically designed to detangle wet hair effectively and may lead to more pulling and snagging. Therefore, the wide-tooth comb is specifically designed for the task at hand, making it the most appropriate choice.
