Many of us wash our hair every day - reaching for the shampoo and conditioner each time we hit the shower - even when we are working from home and staying in thanks to locvkdown.
But a hairdresser has revealed that may not be the best choice, and has explained how often our hair actually needs to be cleaned.
Julien Farel of Julien Farel Restore Salon & Spa in New York said washing your hair too often can do more harm than good.
He told GQ : "If you shampoo every day, it will strip your scalp of all its natural oils and can lead to dry, brittle hair."
Julien recommends washing your hair no more than three times a week, saying his client's hair becomes less greasy when they shampoo less often as the head produces sebum (natural oils) that help to keep hair healthy and soft.
Simply running your hair under water is enough to remove any excess oil in Julien's experience, but using shampoo too often will completely strip tehm away, leaving your hair worse off.
He added the only exception to the rule is people who have an oily scalp, saying if your hair is thick with oil by 5pm in the evening you may need to shampoo more often to balance the levels.
Even if you've been grinding in the gym with a head full of sweat, Julien says a simple rinse without product is still enough to adequately wash your locks - arguing the salt from sweat may even give your hair a nice texture.
And the theory has been backed up by many other hair professionals, including Pantene expert hairstylist Barney Martin.
Barney says even those with naturally greasy and fine hair shouldn't be washing it every day - with her only exception to the rule being swimmers.
