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.
"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."
According to stylist Rosi Fernandez, director of Ananda Ferdi it is not advisable to go for more than a week without washing hair, as follicles become clogged and do not get oxygenated," she explains.
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.
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.
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.
If you want to fix frizzy hair without washing, you need a product that works on dry hair. Comb one whole pump of Almost Everything Cream through your mid-lengths and ends using your fingers. This will again, smooth frizz, as well hydrate dry ends and give your hair a healthy sheen.
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.
“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.
Washing your hair only once a week brings the benefits of natural oils into sharp relief. After all, many hair serums and treatments are meant to replicate the oils produced by the scalp, but excessive shampooing strips the hair of these valuable substances.
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.
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.”
Not washing the hair regularly with shampoo has certain advantages like cost and time saving, reduced exposure to chemicals, and less risk of hair damage. However, it may increase the risk of scalp irritation and infections due to the buildup of sebum, dirt, and sweat.
The no-poo method involves forgoing shampoo containing detergents that strip your hair of its natural oils. Your hair won't smell, because you're still cleansing it. Research the best shampoo alternatives for you: water only, conditioner only, coconut oil, ACV and baking soda, or a no-poo product.
That's known as “no-poo,” and it refers to the idea of giving up shampoo completely (or using shampoo alternatives). While the no-poo method may be a concept only true advocates of the practice understand, many experts agree that it comes with several benefits for everyone—no matter your hair type.
Using a conditioner every day without washing the hair with shampoo can lead to over-conditioning. Too much conditioner can weigh down your hair and make it look limp and dull. It can also overwhelm fine or thin hair and make it look greasy.
Poor hygiene: Habits like not washing your hair enough can lead to a stinky scalp. Pollution: Particles from the environment can attach to your hair, creating a bad smell. Residue from hair products: Excess shampoo (including dry shampoo), conditioner and styling products may build up on your scalp.
In fact, when you don't wash your hair enough, you allow oils and dirt to build up on your scalp and clog your pores, paving the way for actual hair loss. That's why finding the perfect frequency for your shampooing schedule is the key to caring for your scalp and avoiding hair loss.
Disadvantages Of Cold Water
When washed with cold water, there are chances that your enclosed hair cuticles lock in excessive moisture. This may weigh down your hair and make it flat. Also, the moisture increases the binding of your hair strands, resulting in a decrease in hair volume overall.
Another leading cause of an itchy scalp is dirty hair. If you don't wash your hair regularly enough – dirt, oil, and product build-up can cause your scalp to become itchy and irritated. When your hair is too dirty, it can also lead to unwanted bacteria, sometimes turning into dandruff and other scalp problems.
