Do not flatten the style.
Before bed, sweep tresses up and use large bobby pins to create loosely sculpted pin curls as you sleep. 4-6 sections depending on your length will do the trick. When you release and shake out in the morning, you feel like you just left your stylist’s chair.
Create a wave.
Leave your hair damp and create a loose bun on the top of your head, in the morning you will have beautiful waves. Use your fingers to comb through so you don’t flatten your hair. Finish with a light hold hairspray.
Keep it simple.
Another option? Simply take a soft, fluffy scrunchie and place hair in a ponytail on top of your head. Stay away from the tight hair ties that can leave dents in your hair. The fluffy scrunchie move will leave you with natural-looking, voluminous hair the next morning and very few products needed to maintain the mane.
Neaten up your beauty ritual.
When washing your face or applying face creams and serums, make sure to pull hair up and away to avoid frizzing out the hairline. “In this instance, a fabric scrunchie can find a way back into your beauty routine, since you can pull it up loose without the worry of creating big indentations or marks,” says Gonzalez. Shower caps are another must have.
Don’t rely on hairspray to hold your style all night.
The real secret to having your hair last till dawn is in the prep. If your hair doesn’t have the right preparation (styling creme, mousse, application of heat, correct size round brush, etc.) it will fall apart or become flat within a couple hours. Hairspray is quite heavy and can weigh hair down when over used.
Invest in a silk pillowcase.
Do yourself and your hair a favor and invest in a silk or satin pillowcase. Cotton pulls the oils from your hair and helps to dry out a style, creating static, bedhead, and frizz. Try the hair pillow or a satin pillowcase.
Wrap your head.
For curly hair, leave your hair damp then twist your hair into place. Follow by wrapping your hair in a silk scarf and in the morning you will have beautiful, frizz free soft curls.
Apply one pinch of baby powder or cornstarch around the hair line at the scalp before bedtime.
This helps to absorb moisture from nighttime perspiration that causes shorter hair around the face to curl. Gently brush your hair the next morning to remove any leftover product.
Braiding your hair is a great way to achieve curls. The tighter the braid, the tighter the curl. By leaving your hair damp, your locks will be less frizzy in the morning, says Pisacreta.
