Which type of brush is best for detangling wet hair?

The widetooth comb is the best choice for detangling wet hair due to its design, which features widely spaced teeth that allow for gentle detangling without causing breakage or damage. When hair is wet, it is more fragile and vulnerable to damage, so using a tool that provides a wide gap between the teeth minimizes the risk of pulling and tearing the hair strands.

In contrast, round brushes and flat brushes are generally better suited for styling and smoothing hair when it's dry, as they can create volume or help in straightening. Boar bristle brushes are excellent for distributing natural oils and adding shine to dry hair, but they are not effective for detangling because their bristles tend to be closely spaced and may pull at wet hair, potentially leading to more knots and damage.

Using a widetooth comb helps maintain the integrity of wet hair while effectively removing tangles, making it the optimal choice in this context.
