When to wash. Rossi generally tells his patients they should wash their hair once or twice per week. But if you've had chemical treatments that can make your hair drier — such as bleach, perms or relaxers — you might want to wash it less than once weekly to avoid breaking or brittle hair or split ends, he said.
In general, shampooing your hair every day is not inherently bad. It doesn't damage your hair, it doesn't damage your scalp. It does one thing: it cleans your hair and scalp of dirt, oils, product build-up, pollution, and anything else you may not want sitting on your head.
Hair Washing Frequency and Tips
“I recommend washing your hair two to three times a week,” Dr. Icecreamwala says. “If your hair is dry, you may only want to wash it twice a week. If it is on the oilier side, every other day is recommended.”
“I typically advise patients to keep to a standard hair washing schedule, whether it is three times per week, weekly or once per month, regardless of activity level,” she says.
Is Oily Hair Healthy? Oily hair isn't healthy or unhealthy by default. People with an oily scalp can have healthy hair or dry, brittle hair. Your hair needs oil to be healthy, but too much oil can lead to buildup on the hair and scalp.
Not washing the hair regularly with shampoo has certain advantages like cost and time saving, reduced exposure to chemicals, and less risk of hair damage. However, it may increase the risk of scalp irritation and infections due to the buildup of sebum, dirt, and sweat.
While there is no ideal frequency, experts suggest that showering several times per week is plenty for most people (unless you are grimy, sweaty, or have other reasons to shower more often). Short showers (lasting three or four minutes) with a focus on the armpits and groin may suffice.
"The average individual can typically go 2 to 3 days without shampooing their hair. However, if your hair is visibly oily, you may not want to wait that long," she says. "Usually, you can go longer without washing your hair when your hair is styled up, but no one should ever go more than 14 days."
What Is the No-Poo Method? The no-poo method is a hair-cleansing technique that removes shampoo from the equation, says Geeta Yadav, MD, a dermatologist in Toronto. Instead of using shampoo, followers of the practice use alternatives such as apple cider vinegar, a cleansing conditioner, or just plain water.
If you normally wash everyday, it'll take time to get used to washing it less. So start by going an extra day or two in between your normal washes. Rinse your hair with water in between shampoos and try to build up to once a week. When your hair adjusts you'll notice a dramatic difference.
Hot water is more effective than cold water to dissolve dirt, grime, product buildup, and any other forms of scalp buildups. Washing hair with hot water opens up your scalp pores and enables your shampoo [2] to unclog your hair follicles efficiently.
The day after washing, that natural oil (called sebum) that we washed away starts to come back adding softness to our tresses. Sebum also helps to balance the pH levels of your scalp preventing your hair from dryness and breakage.
Prolonged periods of not washing can cause cause buildup on the scalp, damaging hair and even impeding its ability to grow, Lamb said. Grime from dirt, oil and hair product can show up within four to six days for people with finer, straighter hair.
Washing the hair less often can help the scalp remain healthy, prevent itching and flaking, and keep the hair soft and shiny. People with very oily scalps may develop acne on the scalp or along the hairline and may need to wash their hair more frequently to keep their hair looking clean.
According to stylist Rosi Fernandez, director of Ananda Ferdi it is not advisable to go for more than a week without washing hair, as follicles become clogged and do not get oxygenated," she explains.
“Humans tend to perspire at night,” Dr. Goldenberg said. “When you wake up in the morning, there's all this sweat and bacteria from the sheets that's just kind of sitting there on your skin.” So take a quick shower in the morning, he said, “to wash all of that gunk and sweat off that you've been sleeping in all night.”
Showering daily is not necessarily "unhealthy," but you may not need to. For many people, a full-body shower every other day or even every third day is enough. That said, just because you don't shower daily does not mean you want to skip out on personal care.
In fact, when you don't wash your hair enough, you allow oils and dirt to build up on your scalp and clog your pores, paving the way for actual hair loss. That's why finding the perfect frequency for your shampooing schedule is the key to caring for your scalp and avoiding hair loss.
DIRTY HAIR
If you don't wash your hair regularly enough – dirt, oil, and product build-up can cause your scalp to become itchy and irritated. When your hair is too dirty, it can also lead to unwanted bacteria, sometimes turning into dandruff and other scalp problems.
Using a conditioner every day without washing the hair with shampoo can lead to over-conditioning. Too much conditioner can weigh down your hair and make it look limp and dull. It can also overwhelm fine or thin hair and make it look greasy.
