Frequently Asked Questions

Should I Get a Flat Iron with Ionic Technology?

Most professional flat irons have ionic technology. This technology maintains a neutral charge on your hair’s surface with the help of negative ions. As a result, your hair looks smooth and conditioned. Moreover, it also reduces static.

Is It Necessary to Apply a Heat Protector Spray Before Using a Straightener?

When using a professional salon-grade straightener, it’s important to spritz your hair with a heat protector spray. If you have fine hair, you will need extra protection and the spray will prevent any breakage as well as weakening of the hair.

My Hair Is Damaged. Should I Use a Ceramic or Tourmaline Flat Iron?

While both materials are great as they lock in moisture, a ceramic flat iron is what you need when you have damaged, fine hair. This material distributes heat and gives a frizz-free look. Tourmaline is for healthy hair. It increases the shine and the volume of your hair.
