Key Ingredients and Their Benefits

Potassium Persulfate

Potassium Persulfate is a bleaching agent used in the lightening powder. It helps break down natural hair pigment during the lightening process.

Sodium Persulfate

Sodium Persulfate is another persulfate bleaching ingredient used to support the hair-lightening action of the powder.

Hydrogen Peroxide

Hydrogen Peroxide is present in the developer and works with the bleaching system to lighten the hair pigment.

Ammonium Hydroxide

Ammonium Hydroxide is included in the lightening crème and helps create the alkaline environment required during the chemical lightening process.

Cetearyl Alcohol

Cetearyl Alcohol is a fatty alcohol used in the lightening crème and conditioner. It helps provide texture and contributes to the conditioning feel of the formula.

Behentrimonium Chloride

Behentrimonium Chloride is a conditioning ingredient in the anti-brass conditioner. It helps improve softness, smoothness and detangling.

Amodimethicone

Amodimethicone is a conditioning silicone that helps improve hair smoothness, manageability and combability after the lightening process.

How to Use

Before You Start

Always read the complete instructions included with the specific kit before using it. Hair bleaching involves strong chemical ingredients and requires careful application.

Step 1: Perform the Required Allergy and Strand Tests

Follow the package instructions regarding allergy testing and perform a strand test where required before proceeding with the full application.

A strand test can help you understand how your hair reacts to the formula and what level of lightening you may achieve.

Step 2: Prepare Your Hair

Follow the package directions regarding whether your hair should be dry and unwashed before application. Divide the hair into manageable sections.

Protect clothing and your surrounding work area from accidental product contact.

Step 3: Mix the Lightening Formula

Prepare the bleaching powder, lightening crème and developer according to the exact instructions supplied with the kit.

Do not alter the recommended ratio or add extra developer.

Step 4: Apply to the Desired Areas

Apply the mixed lightening formula evenly to the areas you want to lighten.

The kit can be used for all-over lightening, highlights or ombré effects depending on the desired style. L’Oréal also recommends using the included highlighting brush for creating highlighted sections.

Step 5: Allow the Formula to Process

Leave the product on the hair only for the amount of time specified in the product instructions.

Do not exceed the recommended processing time in an attempt to achieve a lighter result.

Step 6: Rinse Thoroughly

Once the instructed processing time has passed, rinse the hair thoroughly according to the product directions.

Step 7: Use the Anti-Brass Conditioner

Apply the included anti-brass conditioner as instructed. This helps condition the hair after lightening and can help manage unwanted warm-looking tones.

Step 8: Apply Semi-Permanent Colour If Desired

If you want to create a vibrant Colorista look, apply the appropriate Colorista Semi-Permanent Color to the pre-lightened hair according to its separate instructions. L’Oréal recommends pre-lightening before applying Colorista Semi-Permanent Color for visible colour results.
