Can I use a flat iron as a curling tool?

Yes, you can get perfect curls by using a flat iron. It’s recommended.

Hydration is essential

Before you race off to buy your flat iron, here’s something I tell everyone considering using a flat iron in their daily routine. No one ever said flat-ironing was a conditioning treatment. It’s damaging, no matter how you slice it.

Heat protectant to your hair is what sunscreen is to your skin. 

It prevents damage and protects your strands natural health. Without it, your hair can become dry, dull, and limp. If you’re considering styling your hair every day or even several times a week, hydration is essential. 

Consider deep conditioning regularly and investing in a heat protectant spray that can be used often. Curling your hair is a commitment–to deep conditioning and heat protectant. But the rewards are well worth it.
