How to use a wide-tooth comb to detangle wet hair safely

When hair is wet, the strands are more susceptible to damage caused by tension. Repeatedly using a brush to remove tangles can therefore increase pulling and contribute to breakage. The American Academy of Dermatology (AAD) advises detangling hair gently and identifies a wide-tooth comb as an option for limiting mechanical stress.

Why does wet hair need extra care?

Wet hair has different mechanical properties from dry hair. Pulling forcefully at a knot can place tension along the strand, raising the likelihood of damage.

This does not mean that all wet hair will break simply because it is combed. The risk is also affected by texture, the condition of the hair, chemical treatments and the amount of force used while detangling.

Why use a wide-tooth comb?

The wider gaps between its teeth allow the comb to move through hair with less resistance. As a result, there may be less need to repeatedly pull at an area where the hair is tangled.

The AAD advises starting at the ends and gradually working towards the roots, rather than running the comb straight down from the scalp. This method helps loosen knots little by little instead of pushing them further down the hair.

How can you detangle hair without excessive pulling?

If there are many knots, separate the hair into smaller sections. Begin at the ends and slowly move upwards, holding the hair near the section being combed to reduce tension on the scalp.

Conditioner or a detangling product can also make this easier, particularly for hair that tangles frequently. The key is to avoid abrupt movements and not to force the comb through a knot that is tightly caught.

Should all hair be combed when wet?

Not always. The most suitable time to detangle depends on the hair's texture and characteristics. Some hair types may be easier to manage while damp, whereas others can benefit from a different approach.

The general guidance is to minimise tension and select a tool suited to the hair type. If hair is breaking often, becoming thinner or there is a sudden change in the amount of shedding, it is worth speaking with a dermatologist.

For this reason, replacing a brush with a wide-tooth comb for detangling wet hair can be a straightforward way to reduce pulling. More important than the tool itself is how it is used: starting at the ends, easing through knots gradually and avoiding excessive force can help protect the strands.
