Here’s How to Use a Flat Iron


Wash and care with keratin.

Start with clean and nourished hair. TRESemme’s Keratin Smooth Shampoo & TRESemme’s Keratin Smooth Conditioner helps calm frizz, making your hair smoother and more manageable. Use it regularly, even on days that you won’t use heat styling tools.

How to use a flat iron – Step 1

Brush your hair - make sure it's dry!

Your hair should be totally dry before you plug in your hair iron. Straightening your hair while it’s still wet can ruin your strands, making them rough, brittle, and dull. Once your tresses are completely dry, gently brush your hair beginning from the ends going up to the roots. Avoid yanking on tangles to prevent breakage.
