Don't use heat-styling tools When you blow dry your hair every post-hair wash, the heat robs your hair of moisture making your hair dry and brittle. Plus, you should know that wet hair is already sensitive and has a higher chance of breakage. So make sure you steer clear of blow drying after a hair 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.
Always ensure hair is dry
If you wash your hair in the evening, it's very important to ensure that it is fully dry before you climb into bed. Hair is more prone to breakage and tangling when wet, so tossing and turning in bed with wet hair can cause it to become damaged, split, or broken.
It is essential to apply a leave-in conditioner or moisturizer after washing your hair. Although conditioners leave a film on the cuticle, it is not sufficient to maintain moisture. It is important to apply a moisturizer or leave-in conditioner while the hair is damp or wet to trap moisture in the strands.
Your Water Is Too Hot
Hot water melts away your natural hair oils, leaving it dry, brittle, and frizzy. Excess heat also lifts your hair cuticles, the outermost layer. When that happens, the cells separate and the cuticle layer can't seal itself—another cause of frizzy hair.
Washing your hair at night gives it more time to dry naturally, which is great for the health of your scalp and hair. Exposing your hair to the highest heat setting of your hairdryer when you're in a hurry can cause severe damage.
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.
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.
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.
After leaving the shower, start by dabbing off excess water with a microfibre cloth. Avoid rubbing the hair vigorously, as the friction causes the strands to tangle and generate frizz. Then, keep your hair wrapped for 10 to 15 minutes.
Hair that's wet and filled with moisture is more fragile than hair that's dry, which can result in snapping when brushed. As such, it's recommended to brush hair in a dry state (guide-to-detangling-curls). This may mean allowing your hair to air-dry post-shower before beginning to comb through hair strands.
There's a way around unruly locks, according to the professionals: give your hair a quick blow dry before bed, making sure that it's around 80% dry before hitting the pillow. "Additionally, you can braid or wrap a silk scarf around your hair to keep it from getting tangled while you sleep," Jones adds.
While excessive heat can cause damage to the surface layer of the hair, air-drying can cause trauma to that inner lipid layer, which will make your strands weaker as a result. Over time, something called hygral fatigue happens, i.e. repeated swelling of the hair.
Use a silk scarf or cloth and tie it like a hairband to make sure your hair does not touch the pillowcase. Once you wake up, flip your hair upside down, gently separate the hair and flip it back up. Resist the urge to brush your hair, as it causes more friction and frizz,” recommends Sabanayagam.
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.
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.
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.
You can use products that have ingredients to hydrate and moisturise your hair. Avocado, coconut, olive and almond oils; aloe vera, shea butter and glycerine can help hydrate and moisturize your hair. Ensure your conditioners include some of these ingredients too in order to lock the water content in your hair.
As for application, you'll want to use it post-shower while your hair is still wet. This way, the conditioning oils and emollients will help trap in the water and seal down the strands' cuticle (which is naturally raised from being exposed to water).
The easiest way to tell if your hair is dehydrated or lacks protein is to do a hair strand test. Take a wet or dry strand of hair and stretch it gently. If it doesn't stretch easily, snaps quickly, and feels dry, brittle or rough, it means you need more moisture.
