This next one falls in the category along side double-stick tape, clear nail polish. MIMICOLOR Cosmetic Hair Touch Up ($48 @ mimiccolor.com) is for a temporary fix of your hair color on your head, eyebrows and even beard/mustache. And it stays in until you shampoo it out. Think of this as one of those cake eyeliners from a few decades ago. Only instead of using a bristled brush to apply, you use a stiff makeup brush. You can buy the two brushes they sell ($14.95 – Brush Kit) or just use your own. Available in four colors: medium brown, dark brown, blonde and red.
