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 hair once a week, or even every other week, can help prevent the hair from drying out while also removing any buildup of hair products. Chemically treated hair and hair of older people may be drier, so not washing it for a week can help prevent it from drying out.
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.
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.
There's no single right answer to how many days you can get by without washing your hair. This comes down to your lifestyle, hair texture, and hair type. For many, two to three days is the most. However, by day five you should definitely give your strands a good wash.
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.
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 you go too long without washing your scalp, Dr. Rubin says you can get a build-up of sebum, hair product residue, and dead skin cells. "All of this can potentially result in clogged pores, which is not good for your scalp health or your hair health," Dr. Rubin explains.
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.
"Two to three times a week is best to 'wash' your hair with a shampoo," Paves says. "For the days in between, I recommend rinsing the hair with water alone. For a fresh feel and smell, you can condition from the mid-shaft out."
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.
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.
Why Greasy Hair Looks Thin. According to hair expert Jean Will of NiaWigs, an oily scalp makes your hair look thinner because a buildup of excess oil at the base of your hair follicles causes strands to clump together. “Greasy hair looks thin because of its oily look,” she said.
You don't wash your hair regularly
This is because fine or thin hair has more oil glands on the scalp, which can cause a build-up of oil, sweat and dirt. If you don't get rid of this on time, the good bacteria on your scalp starts feasting on it and breaks it down, leading to that yucky smell you oh-so-hate.
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.
Non-wash days
Dry Shampoo: Whether it be powder or spray you prefer, there's no question that a dry shampoo can be a lifesaver on the days you're not washing your hair. While it helps absorb oils and odors, it can also help the health of your hair by eliminating blow drying.
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.
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.
You might think it won't hurt, but washing your hair regularly is incredibly important for the health of your hair and scalp. "Shampooing removes sebum or oil that normally coats the hair shaft," says Brendan Camp, MD, a double board-certified dermatologist at MDCS Dermatology in New York.
A clean, healthy scalp promotes hair growth. 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.
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.
How Much Should You Wash? 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.
