Spectra Intense Hydration Mask

1Fine, thin, or straight hair
Direct the nozzle towards any problem areas and massage gently. If you prefer to have more control over the amount of product you are using, spray onto fingertips, and then massage onto your roots.

Protip: You can use Square Root on wet or dry hair. If used on dry hair be sure after you apply the serum that you go in with your blowdryer to dry the solution and add additional volume.

2Naturally wavy or curly hair
Square Root is best to apply to naturally wavy/curly hair when damp. Apply Square Root directly to the scalp with the spray nozzle or spray onto your fingertips then massage gently. Square Root does add slight curl definition so be sure you are running a wide tooth comb or wet brush from your scalp through your ends to distribute the solution.

3Polished look
Square Root has a slight hold and can help with flyaways for a polished look. Hold the hair with some tension, spray Square Root, and then take a clean mascara wand to slick down the hairs. It acts as a very light hold hairspray.
