The bottom line is that dirty hair doesn't grow any faster than clean hair, so you may as well have a clean scalp and fresh tresses. Your strands will look better, feel better, and be healthier, too.

“Washing it more does not cause your hair to grow less,” says Yates, noting that washing your hair less could lead to follicle damage, not the other way around. “A build-up of sebum and/or styling products can clog your hair follicles, leading to follicle damage and ultimately hair loss,” she adds.
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.
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.
Oily and fine or thin hair types should wash every one to two days. This schedule allows for removing buildup and the natural oils to stimulate hair health and growth. Wavy or curly hair and dry or damaged hair types should wash in the range of once every four to seven days.
On average, hair grows about half an inch per month. So, in two weeks, you can expect your hair to grow about one-quarter of an inch or half a centimetre every two weeks.
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.
Depending on your hair type, you can wait three to five days between washes, and we've got the scoop on how to survive the process while you're waiting for sebum production to slow down. We'll admit, the first two weeks are the most difficult, but after about week four, you should see a significant difference.
"If a person is oily, it's fine to wash it every day. If they are dry, it's fine to wash it once a week, but once a week at least for hygienic purposes," Dr. Fusco says. (She clarifies that this is because product can build up on the scalp, potentially leading to clogged pores, irritation, or flakes.)
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.
Your Hair Can Look Thinner
For some folks, going a day or two without shampoo results in gloriously thicker and voluminous hair. But for others — especially those with fine hair — even just a touch of excess oil can have quite the opposite effect.
If at any point your hair feels rough, dry, and brittle and as if random strands are sticking out, this is a sign that your hair is unhealthy and damaged. Under such circumstances, you should consider seeking out treatment for your hair as quickly as possible and not let your damaged hair continue to grow out.
Biotin. Biotin, also known as vitamin B7, is a complex B vitamin that is often touted for having hair growth benefits. And some of that hype may actually be worth it. Biotin has functions in “creating red blood cells, which carry oxygen and nutrients to the scalp and hair follicles,” says Dr. Green.
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.
By rule of thumb, it will take at least six weeks for your hair to transition properly. It usually takes this long because your scalp is so used to its oil being stripped, it will be overcompensating for a while.
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.
"There are specific juices that can be beneficial for the health of your hair and scalp, including aloe vera juice, kiwi juice and cucumber juice." According to Synder, spinach is highly concentrated with vitamin B, which restores shine and promotes hair growth.
We'll cut straight to it: On average, hair grows at a rate of about half an inch per month, or six inches per year. Each hair on your head grows from an individual follicle.
