How do I replace the batteries in my keratin brush?

The Volumizing Keratin Brush runs on two (2) AAA batteries. They are included with your brush. 

Before use, install batteries by sliding open the blue battery-cover plate on the brush handle and install (2) AAA batteries. Replace battery-cover plate before operating brush.

Here's a quick video to show you how to put batteries into your brush:

We recommend replacing the batteries with either rechargeable AAA batteries or AAA alkaline batteries. 

CORRECT DISPOSAL OF BATTERIES
Alkaline, single-use household batteries are typically not accepted recyclables in most municipalities. It is safe to dispose of alkaline batteries in your household trash. You may also take them to a local Home Chemical Collection Center or Household Hazardous Waste drop-off for safe disposal. Rechargeable batteries should be recycled according to U.S. federal guidelines.
