Are you cleaning your hairbrush as frequently as you should be? It’s likely the answer is no and although it may appear to be an unnecessary task, understanding the importance of a clean hairbrush will have you eager to clean it immediately.

For the sake of our luscious locks, knowing how to clean a hair brush is a crucial part of our haircare routine. Anabel Kingsley, a certified trichologist at Philip Kingsley, explains: “Hairbrushes become coated in the products, bacteria, environmental pollution, sweat, oils and dead skin cells that are found on your hair and scalp.”

Brushing your hair isn’t just to de-tangle, it also helps to distribute sebum which helps maintain your scalp’s pH balance. However, a dirty brush can disrupt this balance completely. To prevent inflammation, irritation, and dandruff, it is crucial to follow the expert’s advice on proper brush maintenance.

So how often do I need to clean my brush?

Kingsley recommends you clean your brush every two to four weeks. She explains: “You clean your make-up brushes regularly to remove grime and you should be doing this with your hairbrush too.

“If you use a dirty brush to comb or style your hair, you will be transferring dirt etc back onto your strands and scalp.”

If you’re someone who uses hot hair tools often, celebrity stylist Michael Douglas recommends washing your brush every 20 blow dries.

How do I clean my brush?

If you’re starting to worry that you’ve been inadvertently damaging your hair for years, here’s Kingsley’s step-by-step guide on how to clean your brush:

Comb it: Use a wide-tooth comb and/or your fingers to remove any strands of hair from your brush.

Wash it: Mix your regular shampoo with warm water, or 2 tablespoons of baking soda with 2 cups of warm water, in a container or your sink. Submerge your brush and leave it to soak from 10-15 mins. If your brush is wooden, you should quickly dip the prongs into soapy water and remove it – do not soak it.

Scrub it: Using a toothbrush, gently scrub between the prongs.

Rinse it: Wash it well and shake out excess water. If you are washing a paddle brush, make sure to gently squeeze any excess water out of the base.

Leave it to air dry (don’t blow dry): Leave your brush to dry completely on a hand towel or on your dish rack. Blow-drying it can warp the prongs and damage the shape. Air drying it can take anywhere from 12-24 hours.

If you’re using a barrel brush, Douglas recommends using a separate slim comb. He says: “Comb up through the bristles along the length – not width – of the barrel and pull up the strands in one long motion. This will pick up and remove any strands of hair that are tightly wrapped around the barrel of the brush.”

How often should I replace my brush?

Douglas says as soon as the bristles start to become misshapen due to the heat and prolonged use of a hairdryer, it’s time to replace the brush. “Often brushes can get better as they wear in because the bristles can soften and move into a shape that benefits the hair of the user. You can sometimes find a brush needs to be broken in”, he says.

What is the best brush to buy according to hairdressers

Investing in your hairbrush is a great idea for durability and to avoid hair loss from overly zealous prongs. “A brush with widely spaced bristles is always kinder to the hair as it puts less friction on the hair – as friction can cause breakage in the hair,” says Douglas.

No brush should be too abrasive, Kingsley says: “A good test is to run your brush over the back of your hand. “If it feels harmful or leaves red marks on your skin, it’s too rough for your strands, particularly as hair doesn’t have nerve endings, so it’s hard to tell when you’re damaging it.”

Kingsley recommends a cushioned wooden paddle brush, whilst Douglas says a plastic comb-like brush is fantastic at minimising damage, particularly if brushing through when wet.
