We recommend using the smaller end of the brush for precision
Apply to dry/styled hair.
To cover roots, start with a small amount of powder. Use free hand to pull hair taut at the root. 
Dab on visible roots, starting from the scalp and working outward.  
Repeat as necessary until roots disappear and color looks like new.
To extend highlights, use the side edge of the small end of the brush. 
Use free hand to pull hair taut at the root.
Wherever highlights have grown out, apply blonde powder joining it to the existing highlight.
Note: Let it set for a minute and then you can brush. 
If you put too much on…just blow off with a hair dryer or use the wide end of brush to dust off.
