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.
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.
Shampoo less, condition more
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.
shampoo can strip your hair of natural oils, and using heat products on your hair over and over again causes further damage and breakage, so washing your hair only once a week actually helps keep it in great condition.
Shampooing less often is more of a personal preference. Some people may experience itching when they wash less frequently. But for the most part, shampooing less will only change the appearance and feel of the hair. In extreme cases, you can get clogged pores or dandruff.
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.”
"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."
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.
"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."
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.
Water is effective at washing away dirt, dust, and other water-soluble debris from the hair and scalp without stripping the hair of this sebum. However, Mamelak notes that if there are other oils in the hair (from a haircare or styling product, for example), a good portion of these will be left behind as well.
It may be surprising, but in general, try to shoot for washing with shampoo no more than three to four times a week. This doesn't mean the hair can't get wet, though. Continue to massage and exfoliate the scalp during showers to remove excess dead skin and dirt.
How Many Washes Should You Aim For? While this question truly depends on the nature of your hair and varies from every person, if you have thinning hair, try to wash your hair between 3-4 times a week if necessary; washing thinning hair just 3 to 4 times per week means doing so just about every other day.
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.
Another pitfall of going without shampoo is that if you use styling products, it is especially important to regularly remove impurities, as they can cause scalp irritation, clog pores, and weigh hair down. A water rinse alone is often not enough to thoroughly remove product buildup.
Anabel Kingsley, a trichologist from the Philip Kingsley clinic in London, agrees that hair does not clean itself. "Imagine if you didn't wash your face or underarms for a week - the same logic applies to your hair and scalp," she says. "They are likely to become coated in dirt, smelly, greasy and flaky.
There are four primary factors that cause frizz: the environment, diameter of the hair fiber itself, level of curl, and the amount of damage. Avoid long and hot showers, excess exfoliation, and hot tools like traditional hairdryers and flat irons to prevent frizz.
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.
Q: How often do celebrities wash their hair? Shampoo your hair 1-2 times a week, max. If you go to the gym and sweat, you can rinse the hair and run a light conditioner through the ends, but don't use shampoo.
Even if the hair does not feel oily, frequent shampooing is still essential to keep the scalp environment clean and healthy, so we wouldn't recommend going any longer than three to four days without shampooing.
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.
Going a long time without washing your hair can cause a buildup of a yeast-like fungus called Malassezia on your scalp. Over time, this leads to a layer of dead skin cells that shed from your head in the form of oily, yellow-ish dandruff flakes. Dandruff can also make your scalp red, scaly, and itchy.
A single hair has a normal life between 2 and 7 years. That hair then falls out and is replaced with a new hair. How much hair you have on your body and head is also determined by your genes. Nearly everyone has some hair loss with aging.
