RAINBOW HAIR ESSENTIALS

Forget finding a pot of gold, these Color By You shades are all the treasures you need to create a stand-out spectrum of shades for your rainbow hair look:

STEP 1

PREP WITH BLEACH

Color By You Bleach Primer and mix the powder and developer together. Use a flat application brush to smooth through sections, starting just below the root and blending to the ends. Wait 45 minutes before washing and drying, ready for your rainbow hair transformation.

STEP 2

BEGIN WITH BLUE

Mix a whole tube of Color By You Romantic Pastelizer with a squeeze of Color By You in Blue Jack. Separate hair into sections, then apply your first rainbow hair shade from just below roots to mid-lengths. Repeat until the top section of hair is covered all over.

STEP 3

ADD A POP OF PINK

Mix one full tube of Color By You Romantic Pastelizer with a drop of Color By You in Pink Joys. Sweep through the mid-lengths of hair section by section, then use fingertips to lightly blend and blur the line between the blue and pink hues (making sure you’re wearing gloves).

SAY HELLO TO YELLOW

Time to finish rainbow hair with a touch of gold. Mix the final shade, Lemon Zest, and apply from the mid-lengths to ends in sections. Lightly blend between the pink and yellow colors with fingertips, creating a soft transition of shades.

STEP 5

REVEAL THE RAINBOW

Wait for 20-30 minutes to ensure rainbow hair color is fully developed, then rinse clean before washing and blow drying.
