1. Tame frizz with a toothbrush and hairspray.
Using hairspray to control frizz is a delicate balancing act: use too little and it doesn’t make much difference, but spray too generously and you’ll end up with unpleasantly stiff hair. In order to make sure you have just the right amount to tame frizz, spray an old toothbrush with hairspray and run it over those pesky flyaway strands. It’ll hold your hair in place without turning it into a helmet.
2. Use dry shampoo before you go to bed.
If your hair needs a wash but you know you won’t have time to do that before work or school in the morning, apply dry shampoo before your head hits the pillow at night. The shampoo will work itself into your strands overnight, resulting in clean, healthy-looking hair in the morning.
3. When curling, start with the middle of your hair.
To get full, long-lasting waves using a curling iron, start from the middle instead of the end of your hair. This helps your hair stay wavy for longer.
4. Keep your bobby pins in place with hairspray.
If you have sleek, straight hair that bobby pins usually slide right through, spread out your bobby pins on a towel and spray them with either hairspray or dry shampoo. Carefully pick up the towel by the corners and shake it a bit in order to evenly distribute the hairspray or dry shampoo on your bobby pins, then style your hair and rest easy knowing the bobby pins won’t slip out.
5. Use aluminum foil to help curl straight hair.
For anyone whose hair has trouble holding a curl, try dividing your hair into segments, curling each segment around your finger, and folding it up into aluminum foil squares (the size of the squares will depend on the size of the waves you want). Heat each piece of foil for about 20–45 seconds, wait for the foil to cool, and remove. Use hairspray to hold hair in place if necessary, but in many cases, you’ll find that the curls hold all day.
6. Get volume overnight.
Wash your hair the night before you want to get a voluminous look, add a little volumizing gel, and twist it up into a bun on top of your head before you go to bed (wear a beanie over your hair if you’re worried about frizz). The next morning, blow dry your hair while still in the bun for a couple minutes, then let your now-bouncy hair down.
