Hair washing may seem straightforward, but experts warn that common mistakes can lead to dryness, frizz, and breakage. From water temperature to towel choice, small adjustments can make a significant difference.
Katherine de Rozario, a hairstylist and trichologist at Josh Wood Colour, advises brushing hair gently before washing to remove tangles and prevent damage. Wes Sharpton, a hairdresser at Hairstory, notes that hard water—high in calcium and magnesium—can leave hair dull and brittle; he recommends fitting a water filter if you live in a hard-water area. Water temperature also matters: hot water strips natural oils, so de Rozario suggests using lukewarm water for washing and cool water for rinsing to seal the cuticle and reduce frizz.
Wet hair is fragile, so avoid rubbing it with a towel. Sharpton recommends blotting with a microfiber towel or a cotton T-shirt to minimise friction. If using a regular towel, gently squeeze out excess water first, and ensure it is clean to prevent transferring bacteria. For detangling, use a wide-tooth comb or detangling brush, starting from the ends, as advised by consultant trichologist Anabel Kingsley of Philip Kingsley.
Product application also requires care. De Rozario warns that applying styling products to very wet hair can weigh it down; allow hair to dry slightly first. Kingsley suggests maintaining a 'shampoo wardrobe' for different needs, while Sharpton advocates for detergent-free cleansing creams to avoid stripping beneficial oils. For curly hair, de Rozario says skipping shampoo can minimise frizz; sulfate-free cleansers are a better alternative.
Conditioner should only be applied to the ends, not the scalp, to prevent greasiness, according to de Rozario. Sharpton recommends leave-in conditioners for added heat protection. Finally, over-washing is a common error: Jonathon Andrew, a celebrity hairdresser, advises washing twice a week with a double shampoo each time, using the first wash to remove buildup and the second to deep cleanse. If reducing frequency is challenging, try a non-wash day at home and use dry shampoo or updos to mask oiliness.
