Dermatologist and RealSelf contributor Sejal Shah explains that the average person could usually wash every other day or go up to three days without doing so. “If you wash your hair too often, you run the risk of stripping it of its natural oil and drying it out and leaving it prone to breakage,” she said.
"Those who have thin or fine hair, exercise, and sweat during the day—or those who live in a very humid place—should be shampooing their hair daily," Dr. Chen says. "Those with thicker hair, and those with a dryer scalp, can go a few days without washing their hair."
Dermatologists universally agree
The idea of needing to shower every 24 hours is great for soap manufacturers, but most people only need to take a few showers a week, depending upon their activities and environment.
Generally, if your hair isn't greasy or dry, you should cleanse it every two to three days, King recommends. But if you wash hair too often for your hair type, "it could be very drying to the hair, depending on the ingredients in the shampoo," King says.
It is unlikely you need to wash your hair every day, even if you have short, thin hair, washing your hair once every 2-3 days is advisable. Washing your hair too often can cause the natural oils in your scalp to under or overproduce, leaving you with either overly oily or dry hair.
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.
“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.”
“A morning shower can help shake off sleep inertia and get you going, while an evening shower can be a relaxing part of a pre-bed routine,” says Michael Grandner, director of the Sleep and Health Research Program at the University of Arizona.
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.
Generally speaking, older adults may only need to wash their hair around once per week. For seniors who are hesitant to wash with greater frequency, dry shampoos can be effective in the days between wet washing.
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.
Washing your hair every day can strip away more oil than it should from your hair, which leaves your hair drier and more likely to break. Washing your hair every day can cause dryness, and that makes your hair much more prone to split ends. Split ends are the enemy of happy and healthy curls!
Signs you're washing too often
You may experience the following: Dry, brittle hair. Hair breakage. A dry, irritated or itchy scalp.
How often should a person wash their hair? People with oily hair or who use hair care products daily should consider washing their hair once every 1–2 days. People with dry hair can wash their hair less frequently. Those with textured or coily hair should only wash it once every 1–2 weeks.
When incorporated into a bedtime routine, a nighttime shower may help send your brain the signal that it is time to sleep. Showering at night also ensures you will be cleaner when you go to bed, reducing the buildup of sweat, dirt, and body oils on your bedding.
Benefits of Showering in the Morning
Another benefit to morning showers is that you cleanse yourself of any night bacteria. Research shows that humans tend to sweat more at night than in the morning. A quick morning shower can help you feel less sweaty.
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.
"Showering twice a day not only maintains scalp health, but also helps eliminate unwanted germs in our body," Dr. Cua explains. He further emphasizes that according to a study quick baths also help improve mood and reduces fatigue after a long day.
Cold showers can help reduce inflammation, relieve pain, improve circulation, lower stress levels, and reduce muscle soreness and fatigue. Hot showers, meanwhile, can improve cardiovascular health, soothe stiff joints, and improve sleep.

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.
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.
