Garnier Nutrisse Truly Blonde Ultimate Lightener D+++ Permanent Hair Colour - Yellow

This Garnier Nutrisse Ultimate Lightener D+++ can lighten your hair by up to 8 levels, allowing for significant blonde transformations.

Yes, it features an anti-yellow formula specifically designed to counteract unwanted brassy or yellow undertones, helping you achieve a cleaner, truly blonde result.

Yes, this is a permanent hair colour. The lightening effect and color will not wash out, though natural hair growth will show roots over time, and color may gradually fade with washing and sun exposure.

After lightening, use shampoos and conditioners specifically for color-treated or lightened hair. Incorporate regular deep conditioning treatments to combat dryness. Using purple/violet toning products will help maintain your blonde, and minimize heat styling.

Yes, it is absolutely essential to perform a skin allergy patch test 48 hours before each use, even if you have used hair colour products before. This is to check for any potential allergic reactions.

> Info needed: The general recommendation is to be cautious. Lightening previously colored or chemically treated hair can lead to unpredictable results or increased damage. Always consult the product's specific instructions or a professional if you have doubts.

As a permanent lightener, the actual lightened hair will remain blonde. However, color vibrancy can subtly shift over time due to washing, sun exposure, and pollution. New root growth will also appear, requiring touch-ups.

Ensure you applied the product evenly and saturated all strands. The development time might have been too short; always perform a strand test. Uneven results can also stem from previous hair treatments or inconsistent application. Do not re-lighten immediately; wait at least 2-4 weeks and consider professional advice.

While this product has an anti-yellow formula, some underlying tones might still appear. Ensure you followed the instructions carefully. Use a dedicated purple or violet toning shampoo and conditioner regularly to neutralize these tones. For persistent brassiness, a professional toner might be needed.

Lightening can be harsh on hair. Immediately follow with the nourishing conditioner provided. Incorporate deep conditioning masks and leave-in treatments into your routine. Minimize heat styling and be gentle when brushing wet hair. If severe, consult a haircare professional.

Immediately rinse the product out with plenty of water. This could indicate an allergic reaction. Seek medical attention promptly. Always perform a patch test 48 hours beforehand to identify potential sensitivities.

Ensure you are mixing the components exactly as instructed in the leaflet. Check the expiration date of the product. If the mixture doesn't look homogenous or isn't developing as expected, do not apply it to your hair. Contact the manufacturer's customer service.
