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.
Additionally, washing the hair at night may not be suitable for every hair type, for the simple reason that if your hair or scalp is already oily and greasy, it will get oilier overnight, because of the skin's natural ability to secrete oil at night. This, in turn, can reduce the hair's elasticity and cause dandruff.
For this reason, many people with curly hair prefer to wash their hair in the morning to give it plenty of dry time. You should also take note of your hair's porosity. This will determine things like how long it takes your hair to dry and even plays a part in how your hair absorbs and retains moisture when you wash it.
Nighttime: Many people prefer to wash their hair at night before they head to sleep. This is an ideal option for those who don't want to use excessive heat on their hair and would rather let their hair dry overnight. You can simply wash and condition your hair, gently comb through your strands, and head to bed.
Hair gets greasy overnight as at night time your body produces more sebum. A normal substance, sebum coats and protects your hair shaft providing that glossy shine. Dirty pillowcases, washing too little or too often, and agitation as you sleep can all contribute to over production.
There are high chances that if you wash your hair at night, you might go to sleep with wet hair. Practicing this can not only make you sick, but your hair will also appear more tangled than usual. This happens because the cuticle of hair remains open after the wash.
Showering and washing your hair in the evening before bed can help to give you back more precious time in the morning for sleeping, eating a good breakfast, exercising, preparing for the day ahead, or simply getting ready in a relaxed manner and without rushing.
Travers does say that if you must wash your hair at night it's a good idea to dry it before you go to sleep or you can put your hair in a loose braid to help contain your tresses and reduce knotting and breakage.
When your hair is wet, it's more fragile and prone to breakage, says Jasmine Burnside, a hairstylist in New York City. "Going to bed with wet or damp hair will most likely lead to more friction on the strands, ultimately leading to potential damage." That's why she says it's something that she advises against.
"You can still wash your hair at night, but either dry it before getting in bed, or loosely braid it. This will prevent it knotting and becoming tangled as you sleep and when you take it out in the morning your hair will have soft waves."
MORNING WASHERS – THE CLEAN STARTERS
These play a key role in causing scalp irritation, and dandruff. What's more, if you have particularly fine hair or are prone to oily or greasy hair, you may find you produce a lot of oil overnight and your hair doesn't have the same healthy shine when you wake up.
“Shampooing your hair twice is beneficial because it allows for proper cleansing, giving you longer periods of time with a clean scalp and keeping away the oily hair problem,” he says. “It also keeps you away from over-shampooing your hair, which is a mistake that most women make.”
Don't sleep with your hair tied up!
Instead, sleep with it down, or if you have to tie it back, go low with a ponytail or loose braid at the nape of your neck. Try pulling your hair up with a soft scrunchie instead!
It is best to sleep with your hair down if your hair length is short. This also lets the air flow freely through your hair, which makes you sleep more comfortably. On the other hand, if you have long hair, it is recommended to tie your hair loosely to prevent knots and breakage.
The low bun is an absolute classic hairstyle for healthy hair. With that bun sitting nicely on the nape of your neck, gravity won't be tugging on your hair follicles anytime soon. If you've done a low bun before, you might like to create a ponytail before twisting your hair around itself.
It should only be slightly damp, and definitely not completely wet. Sleeping with completely wet hair damages the follicle and causes breakage, so you'll want to blast it with the hairdryer to dry out 70 per cent of your hair, or let it naturally dry till it's just a little damp,” says Sabanayagam.
Pick a Braid, any Braid
Braid your hair before going to sleep. This old trick works every time and is one of the best ways to wear your hair when sleeping. It not only protects your hair – stopping it from tangling and breaking – but also gives you gorgeous beachy waves the next day and cuts down on frizz.

In addition to affecting the hair, it also affects our scalp and body.
"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."
“I would recommend avoiding hot showers or baths before bed; using a shampoo designed for greasy hair; applying dry shampoo to the roots; tying your hair up to prevent the sebum traveling down the hair shaft; and making sure you're washing your pillowcases regularly to prevent buildup of grime and sweat,” Kate shares.
