Jessica McGuinty found caring for her curls so challenging, she started her own line of products and is now the owner of a successful small business, Jessicurl. She shares some tips on how to keep curls from frizzing and how to give straight hair a boost of volume.

"You have the right to remain curly!"

A curly-headed person's worst enemy is the frizz. Here's how Jessi keeps the enemy far away:

Applying styling products when your hair is soaking wet. Keep a spray bottle with water nearby so that if your hair gets even a little dry, you can wet it again.

"Scrunch" curls to dry them instead of rubbing your scalp with a towel.

Never use a brush. For wavy hair, use a wide-tooth comb in the shower while your hair is saturated with conditioner.

Use a microfiber towel instead of terrycloth. "Terrycloth is the anti-best friend for curls," she says, "and wrapping it up in that turban can make your curls all wonky and weird. A microfiber towel absorbs water without making your hair frizzy."

Sleep on a satin or silk pillow. "Your hair pulls across it and the cotton actually sucks moisture out of your hair," she explains. Satin and silk pillowcases will also help get your hair softer and keep frizz at bay.

Master the "plunk" (Click on the video for the demonstration)

1. turn your head upside down
2. wrap towel or t-shirt around your head
3. twist the sides
4. tie or clip the ends behind and leave on for 20 minutes.

Straight hair gets beachy, even in the middle of winter

Got straight hair? Jessi's got you covered as well. "A lot of straight-haired people write me and ask how they can get more volume and sometimes they want to get some 'beachy' waves," Jessi says. Some of her suggestions include:

Spritz on a mixture of Epsom salt and water: Jessi recommends mixing 1 teaspoon of Epsom salt per 8 ounces of water in a spritz bottle (any more might dry out your hair and make it brittle). After spritzing, style as usual. "The #1 ingredient in all of the new "beachy" hair products is Epsom salt... There's something in the way Epsom salt reacts with your hair," she says. "You can comb it out if you want it to be straight or you can scrunch it up if you want it to be wavy." Great "beach" hair without all that sand? Sold!

Rinse your hair upside down in the shower. Instead of standing upright where the water beats down on your hair, bend over and let it cascade over it, pulling it away from your scalp. "It gets it off your scalp and gives it some volume," Jessi says. "If you blow-dry upside down, it gives even more volume!"
