"My guest came in with very blotchy uneven color," says Annette Gavidia (@hairbyannetteg), owner of Sei Bella Studio, West Covina, California. "She arrived with 1 inch of virgin hair and tons of brass." 

Here Gavidia shares the details for this correction:

Formula 1: (prelighten) Schwarzkopf Blondme lightener with 30 vol & 1/8 oz Olaplex

Formula 2: (prelighten) Schwarzkopf Blondme lightener with 10 vol & 1/8 Olaplex

Formula 3: (shadow root) Pravana 7.11 with an inch of ash blue booster and zero lift developer

Formula 3: (toner) Fanola Silver with 3.5 vol developer

Step by step:

Step 1: Foil back to back with formula 1, leaving 2 inches off the scalp.

Step 2: Apply formula 2 to the hair that is already a level 7/8.

Step 3: Process for about 45 minutes.

Step 4: Rinse, apply Olaplex #2 for 10 minutes. Shampoo and condition.

Step 5: Dry the hair and relighten any hair that was still a level 8 or darker. Use another batch of formula 2 for 30 minute. Shampoo using Fanola's No Yellow shampoo. Towel dry.

Step 6: Apply formula 3 from root down 3 inches. 

Step 7: Apply formula 4 from zone 2 to ends. Process both formulas for 20 minutes. Rinse and condition the hair.
