The Formulas

Formula A (base):
Redken Color Fusion 30g 6BC + 15g 7BC + 10-volume developer
Formula B (tone 1):
Color Fusion 40g 7BC + 10g 7CR + 10-volume developer
Formula C (tone 2):
Color Fusion 25g 8GR + 5g 7BC + 10-volume developer
Formula D (glaze):
Redken Shades EQ 08C + 08WG + Redken Shades EQ Processing Solution

Steps

1. On dry hair, start the color application: Sara begins with Formula A, Formula B and Formula C in three separate bowls. 

  • Formula A: Apply to the base.
  • Formula B: Apply to the mids. In areas where Sara wants to maintain tonal depth, she’ll use a wider application.
  • Formula C: Apply to the ends.

Pro Tip: Avoid color transfer by keeping a towel in your apron to wipe your hands in between each application.

2. Process and cleanse. 

3. To enhance vibrancy, apply Formula D as a glaze. Process and cleanse.

4. Apply Redken Acidic Bonding Concentrate 5-Minute Mask, rinse and begin styling.

5. Finished look:
