Short answer: There's no single right answer - but there's a real difference between "wet" and "soaking wet with conditioner still in", and that difference decides whether brushing helps or hurts your waves.
3 facts worth knowing
- Wet hair is mechanically at its weakest. When hair gets wet, the cuticle layer opens and hydrogen bonds inside the strand loosen, so hair stretches and snaps more easily than when dry. That's why most hair-care guides recommend gently working out knots with your fingers on wet hair instead of brushing them out.
- The "100 strokes a day" rule is a myth with no evidence behind it. The American Academy of Dermatology explicitly pushes back on the idea - excessive brushing adds friction, not shine. The rule likely traces back to an anecdote about Empress Sisi, not research.
- Less brushing correlates with less hair breakage. A small study (Kiderman et al., 2009) tracked women over four weeks: hair brushed less often showed less shedding than hair brushed frequently. Not a large sample, but the direction is clear - every stroke is mechanical stress, even when it feels good.
2 voices that disagree
- The classic line (ÖKO-TEST and most German hair-care guides): Don't comb wet hair at all if you can avoid it. Detangle before washing instead, and if you must deal with knots while wet, use your fingers or a wide-tooth comb with plenty of conditioner.
- The wave-specific counter-voice (eMediHealth): For wavy hair, brushing completely dry is the bigger frizz risk. The best moment is slightly damp hair right after conditioner - there's still enough slip left, and the wave pattern doesn't get torn apart. Brush it bone-dry and the wave tends to break apart into frizz instead.
Both are right - they're just talking about different moisture levels. "Wet" like straight out of the shower is not the same as "damp" after squeezing out excess water with conditioner still in.
1 question for you
Do you reach for a brush right after the shower, or detangle with your fingers first? If you brush: do it on soaking-wet, conditioner-coated hair, with wide teeth, starting at the ends and working up - never from the roots down, or you just push the knots further down.
Who this matters most for
Especially for 2A-3A waves: unlike the curly-girl community, where brushing is often treated as an outright sin, it's usually fine for wavy hair - as long as timing and tool are right. A wooden comb with wide teeth or a dedicated detangling brush is gentler on the structure than plastic with tight, sharp teeth.
