Wella Koleston Perfect Me+ Pure Naturals 6/0 Dark Blonde is a permanent hair dye suitable for both professional and private use. The 60 ml tube contains a highly effective color formulation with ME+ technology, which provides balanced color results with natural depth and shine. The product covers up to 100 percent gray hair and can lighten hair by up to three levels. The ME+ technology significantly reduces the risk of developing new allergies to hair dyes and minimizes hair damage with repeated use. This dark blonde shade (6/0) delivers pure, naturally-looking color results for various hair types. The product requires a simple 1:1 mixing ratio with separately sold hydrogen peroxide developer. Although the ME+ technology reduces allergy risks, users should always perform a patch test 48 hours before application and carefully follow all safety instructions. Individuals with previous allergic reactions to hair dyes should not use this product. The formulation is part of Wella's Pure Naturals collection, which offers authentic, naturally-looking hair color with enhanced safety features. For optimal color care and hair conditioning, complementary Wella Invigo products are recommended. The product has a volume of 60 ml and is designed for a single application.
