A: Generally speaking, it’s not a good idea, at least not with a traditional bristle-brush. The more modern “tined” brushes used for
blow-dry styling, are acceptable, provided they have widely-spaced tines.
The issue at hand is that wet hair is much more fragile and susceptible to damage than dry hair.
Fine-toothed combs and finely-tined brushes (as well as bristled-brushes) all exert a lot of pressure on the wet hair because they
either a) try to force the hair between tightly-spaced teeth or tines and/or b) try to direct the hair in multiple directions at
once. Wet hair will stretch to the point of misshapenness, and often break off when placed under too much stress.
The best way to detangle and groom wet hair is with a wide-toothed comb. You can use the
wide-tooth comb first and then work your way to finer-toothed or tined styling tools.
(Note: While natural bristle brushes are excellent for distributing natural oils and
removing dirt from the hair when used to brush dry hair, brushing the hair too much is not good. Over-brushing can lead to
split-ends and breakage. Therefore, while you should brush the hair every day, only do so until the hair is smooth and tangle-free.)
