How To <em>Smooth Like a Pro</em>

How To Smooth Like a Pro

Follow these steps to get your smoothest, sleekest style ever.

1. Start with fully dried hair. Refer to Smoothing Pik Blowout Prep for instructions.

2. Divide into four segments, separating the back from the front, and clip.

3. Unclip one segment and mist with Neuro Protect. Take a small section of hair from within the segment, about the same width as the plates of your smoothing iron. Glide the Neuro Smooth+ 1.75" through the hair, starting near the roots close to the scalp. Hold it firmly, but not too tight, to avoid pulling or damaging the hair. Follow the movement with your hand or a comb and keep the iron moving smoothly and evenly.

4. Repeat for each section of hair, working from the bottom layers to the top layers. Make sure to always clamp the iron close to the roots and glide it down to the ends.

5. Once all the hair is straightened, let it cool for a few minutes. This will help the straightened style set and stay in place.
