Frequently asked questions

Can Flat Irons Damage Relaxed Hair?

 Yes, you’ve already put your hair through the chemical process of the relaxer, so it is more prone to heat damage than flat ironing hair that has not been through a chemical treatment process like a relaxer. 

Should You Use Heat Protectant on Relaxed Hair?

Yes! Putting direct heat on your hair evaporates the water molecules in the inner structure of our hair, changing its properties and allowing us to change our hair’s curl pattern. Sadly, it also causes damage. A heat protectant can help lessen the damage done.

Is Titanium or Ceramic Better for Relaxed Hair?

It all depends on the hair type, rather than if the hair is relaxed. Choose a flat ceramic iron if your hair is soft, thin, and easy to straighten. A titanium straightener is the finest option for coarse, thick, and obstinate hair.

How Often Can You Straighten Relaxed Hair?

You should straighten your hair no more than once a week.
