L'Oreal Preference BALAYAGE Highlights - Black

Since this is a permanent lightening kit, the highlights themselves will not fade. However, your natural hair will grow out, and you will eventually see your root line. Typically, a touch-up or reapplication might be desired every 8-12 weeks, depending on your individual hair growth rate and desired look.

This kit is optimized for natural dark blonde to light brown hair. While it *may* be used on previously colored hair, results can be unpredictable, especially if the previous color was very dark or had a significant color build-up. It is always strongly recommended to perform a strand test first to gauge the outcome and hair condition.

Yes, absolutely. An allergy alert test (patch test) must be performed 48 hours before *each* application, even if you have used hair color products before. Allergies can develop suddenly and unexpectedly, and this test is crucial to help prevent severe allergic reactions.

This kit is specifically formulated for natural dark blonde to light brown hair. Using it on significantly darker hair (e.g., medium brown, dark brown, or black) may result in an undesired orange or brassy tone, or simply no visible lightening effect. It is not recommended for hair darker than light brown.

To maintain healthy and shiny highlighted hair, use shampoos and conditioners specifically formulated for color-treated hair, incorporate a weekly deep conditioning mask or hair treatment, minimize heat styling (and always use a heat protectant), and protect your hair from excessive sun exposure with hats or UV-protective products. Regular trims also help keep ends healthy.

This kit is designed for a balayage effect, which typically involves highlighting away from the roots, creating a soft, blended transition. Applying lightener directly to the roots in a block fashion can create a harsh demarcation line and is generally not recommended for achieving the intended diffused balayage look. The included root blending mask helps soften the existing root area after highlighting.

Immediately rinse eyes with plenty of water for at least 15 minutes, holding the eyelids open. If irritation persists or if there is any concern, seek medical advice promptly. Always wear the gloves provided and exercise extreme caution during application to prevent accidental contact.

This often occurs if the lightening process wasn't long enough or if your hair has strong underlying warm tones. Use a purple toning shampoo and conditioner, designed to neutralize brassy yellow tones, a few times a week. For future applications, ensure sufficient processing time within the recommended limits or consider a professional consultation.

Uneven application is a common cause. Ensure hair is sectioned cleanly and the product is applied consistently and thoroughly using the provided tools. For future applications, practice your technique on a hidden strand first or ask for assistance. For existing unevenness, a professional might be needed for correction.

Lightening can be harsh on hair. It's crucial not to exceed the maximum processing time. Deep condition your hair regularly with a restorative mask. Minimize heat styling and use leave-in treatments or oils to add moisture and strengthen strands. If damage is severe, seek professional advice.

The root blending mask is key to a soft transition. Ensure it was applied correctly and thoroughly as per instructions. For future applications, focus on a lighter, more diffused application of the lightener closer to the roots, allowing the mask to work more effectively in softening the blend.

This could be due to insufficient processing time, incorrect mixing of the product components, or if your hair is significantly darker than the recommended natural dark blonde to light brown range. Double-check instructions for mixing and timing carefully. If your hair is very dark, this kit may not be strong enough to achieve noticeable lightening.
