How do I use Dyson Chitosan™ Post-style serum?

Dyson Chitosan™ Post-style serum should be applied on dry, styled hair to define your look.

Start with one or two pumps, sheer gently through palms and work through the hair with your fingers to smooth, define and enhance your style. Add more product as needed.
