How often should you brush your hair?

 

How often you should brush depends on your hair type and scalp:Straight/fine hair: Can handle daily brushing. Once or twice a day is ideal.Wavy hair: 2-3 times a week is enough. On other days, detangle with fingers or a wide-tooth comb.Curly/coily hair: The best time to detangle is on wash day, since the hair is weaker. Daily brushing causes frizz and breakage.Oily hair: Frequent brushing helps distribute oils, but don’t overdo it or you’ll stimulate more oil production.Dry scalp: Reduce brushing so you don’t strip away the little oil that’s there.2. Benefits of brushingDistributes natural oils from roots to tips for shine.Cleans the scalp and removes dead hair.Improves blood circulation in the scalp.3. Mistakes to avoidOver-brushing: More than twice a day weakens hair and causes split ends.Brushing from the roots: If there are tangles, start at the ends and work your way up.Brushing when wet: Hair is weaker when wet. Use a wide-tooth comb and be gentle.4. General ruleMost experts say once in the morning and once at night is enough. If you have long hair, 3 times a day can help avoid knots.

A brush through history

Combs and hairbrushes, and therefore the practice of hair grooming, date back to prehistoric times. "Humans have always used what they had to hand to create tools for both cleanliness and adornment, so brushing would have been important globally throughout history," says Rachael Gibson, founder of The Hair Historian.

The tangled physics of hair

Consider the idea that frequent hair brushing increases hair growth. Over 46% of respondents in a 2025 survey still believed this claim. But that is a myth, according to Nikki Corzine, a hair salon owner in California, US. You cannot make your hair grow faster by brushing it more, says Corzine. 

Scientists who have devised formulas to precisely test the impact of grooming on hair damage, in fact, suggest that overbrushing can even cause some damage and hair loss.

One team of researchers created a test to mimic what happens when two hair strands loop around each other into a knot and are then pulled to untangle them. More combing caused hair to crack from the inside, at least for those prone to split ends. While healthier hair fared better, it still started splitting after repeated pressure, with cracks forming from the outside in.
