Collect peroxide, clarifying shampoo, a protein-based conditioner, powder lightener, distilled water, blond hair dye, a disposable shower cap and rubber gloves. Also secure a bowl and a brush.
Combine equal parts peroxide, clarifying shampoo, protein-based conditioner, powder lightener and distilled water in a bowl. Mix all ingredients together to create the soap cap formula.
Separate the hair into small sections, and brush the soap cap formula into the strands. Distribute the formula evenly, and make sure that your hair is completely covered. Wearing rubber gloves, lather the mixture through the hair. Cover the head with a disposable shower cap, and let the soap cap formula set until the hair reaches the desired level of lightness.
Rinse out the soap cap formula. Using the selected dye, color your hair blond. Allow the dye to set until your hair is the preferred shade. Rinse out the dye, and style your hair as desired.
