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.
Is it bad to wash your hair every day? While some may need to wash their hair more regularly than others, washing your hair every day is considered a bad thing. Over-washing on any hair type will remove important natural oils, known as sebum, and will leave your hair feeling dry and brittle.
Jeff Chastain, a hairstylist in New York City, recommends that women get their shampooing down to once or twice a week. Less washing, he said, means stronger and longer hair. And women with curls need not wash their hair as often as others.
Coily hair: Both Courtney and King suggest washing once per week for optimal hair growth. "Don't forget to follow with conditioner," King adds. "It's equally as important to condition as much as it is to cleanse."
She says it's more important to consider your hair type, texture and amount of oil production you usually experience. “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.
Everyone's scalp can get a little oily sometimes. But a little oil is OK! Oil (sebum) helps protect and support healthy hair. But an abnormally oily scalp can feel like a problem if it makes your hair feel greasy or dirty all the time.
For the average person, every other day, or every 2 to 3 days, without washing is generally fine. “There is no blanket recommendation. If hair is visibly oily, scalp is itching, or there's flaking due to dirt,” those are signs it's time to shampoo, Goh says.
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.
As counterintuitive as it may seem, the more you wash your hair, the more you need to. Daily shampooing actually strips your hair of healthy oil, which causes frizz, split ends, and—maybe worst of all—the overproduction of sebum (or your own natural oil). The sebum is what's behind that urge we get to wash our hair.
There are some benefits to not washing your hair, especially if you have dry hair, damaged hair, or tightly curled hair. Depending on your ethnic background, less frequent washing can also help reduce breakage and hair loss.
"You can use dry shampoo to lengthen the time in between washes, to absorb sweat after workouts or to just refresh hair for a 'fresh-styled look' without the hassle of getting hair wet and blow drying it."
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.”
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.
Unlike shampoo, conditioner can be used everyday, as it re-hydrates hair and replenishes nutrients. You might also want to consider conditioning on the days you don't shampoo (remember, keep that to two or three days a week). It'll help rinse away grime on the non-shampoo days, and re-hydrate following a shampoo.
Many doctors say a daily shower is fine for most people. (More than that could start to cause skin problems.) But for many people, two to three times a week is enough and may be even better to maintain good health. It depends in part on your lifestyle.
Shampoo as we know it today has only existed for about 100 years. Prior to 1903, the act of hair washing ranged from a head massage with fragrant oils to boiling pieces of “shaved soap” bars in water. There are a range of early methods, however let's focus on the past hundred years or so.
Those with fine or thin hair, however, may find their hair looks greasy after just one day. It's all to do with the amount of oil your scalp produces, as well as how well your hair can carry that oil.
Greasy hair after washing may be due to a person's hair care routine, an overproduction of sebum, environmental factors, or underlying health conditions. People may be able to stop hair from becoming greasy as quickly by using a gentle clarifying shampoo and lightweight, non-greasy hair products.
The bottom line is that dirty hair does not grow faster than clean hair, so you might as well have a clean scalp and fresh hair. Your hair will look better, feel better, and be healthier as a result.
Using lukewarm water is best because it activates the cleansers in your shampoo while protecting your hair and scalp for your healthiest hair growth.
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.
Yes, you can wet natural hair everyday, and it is actually advised to do so to maintain moisture. Let's be clear though: by wetting your hair, we don't meanwashing it. We simply mean rinsing natural hair either in the shower or spritzing water over your hair.
Not washing your hair regularly can make the scalp flaky and lead to dandruff. It will make you feel itchy and you can also get rashes on your scalp. “You can develop major dandruff problem if you don't wash your hair for 1 or 2 weeks,” she warned.
