Tiffany Massey (@tiffanymhair) of Structure Hair Studio (@structurehs) in Dahlonega, GA. says this box-dyed brunette (a natural level 8) wanted to go solid platinum blonde. 6 hours later, mission accomplished! Get the how-to: Step 1: Use a soap cap mixture with 40 volume + Olaplex on the colored hair. Step 2: Highlight every single strand of hair in foils using bleach and progressive lightener on zone 1 (root area) starting with 10 volume. Use bleach and progressive lightener on colored hair starting with 20 volume and Olaplex. Process for 30 minutes, no heat. Step 3: Rinse. Apply Pravana Ultra Highlift Violet + 20 volume (plus Olaplex) on mids and ends. Rinse and apply step 2 Olaplex. Process for 15 minutes.
