People disagree about the correct number of times to wash their hair per week, with controversy still burning among health experts and the general public.
Experts have revealed that there is no one-size-fits-all answer about how often we should wash our hair or what we can do to maintain it on rest days.
How often you should brush your locks may depend on several factors, including the type of hair, how greasy your scalp is, and your activity levels.
Once or twice a week
Anthony Rossi, MD, an assistant dermatologist at Memorial Sloan Kettering Cancer Center in New York City, said washing hair too much causes it to dry out, while oil buildup from not washing enough can also lead to odor.
Rossi explained that he generally tells his patients that they should wash their hair once or twice a week, according to CNN.

But if you have chemical treatments that can make your hair drier, like bleaching, perming, or using certain ointments, you might want to wash it less than once a week to avoid hair breakage, split ends, or split ends, he says.
Oily scalp
And if your scalp is extremely oily, you may need to wash it once a day, according to the American Dermatological Association website, while your age can play a role, too.
In addition, he noted that during puberty there is an increase in hormones, and thus the sebaceous glands can become enlarged.
Rossi said it was the reason why people got acne in their teens.

He also added that children may experience more oily scalps during their adult years, so washing their hair more often may be beneficial.
aging
In turn, the American Dermatological Association says, our scalps produce less oil as we age.
She explained that our hair may be more prone to dryness or breakage if it is curly or frizzy.
Washing it a lot can also exacerbate this, so thick and curly hair in general does not need to be washed daily or even weekly, according to the association.
But you should wash it at least every 2-3 weeks to keep your scalp and hair clean and healthy.
