Brow & Lash Color Oxidizer 1.8% LeviSsime Lash Activator

The oxidizer works just like any other oxidizer. I also choose the same brand for my paint.

"I always choose this same brand's good quality developer when I purchase hair dye."

I absolutely love the hair dye and developer from this company! The size of the bottle is probably enough for a lifetime. If there was a smaller volume available, I would gladly purchase it. I only use about half (if not less) of this jar before it expires. Unfortunately, I have to throw away the rest.
