{"product_id":"black-tone-on-tone-hair-treatment-mask","title":"Cool Black Hair Tone Correcting Mask","description":"\u003cp\u003eBring depth and balance back to dark hair with Naissant Cool Black Hair Toning Mask, a toning treatment designed to neutralize unwanted red and orange undertones while treating hair with skincare-inspired care. This ammonia-free, peroxide-free, paraben-free, sulfate-free and DMDM hydantoin-free formula uses a pH-balanced base to help maintain a cool, even black tone on dyed black and very dark brown hair.\u003c\/p\u003e\n\u003cp\u003ePowered by Naissant Ultra N high-purity pigments with a cool blue base and balancing modulators, this mask targets warm reflections that appear as hair oxidizes and fades. It is ideal for levels 1–3 (and level 4 when visible red appears), especially on colored hair that tends to turn reddish after repeated washes. By softening red and orange undertones, the color looks like a cleaner, cooler, more professional black.\u003c\/p\u003e\n\u003cp\u003eOur science-backed blend of hyaluronic acid, biotin and hydrolyzed collagen targets the look and feel of damaged hair from root to tip. Hyaluronic acid provides deep hydration for softer, smoother, glossier strands. Biotin helps fortify the hair fiber and reduce the appearance of breakage, while collagen supports elasticity and a fuller-looking, more resilient mane.\u003c\/p\u003e\n\u003cp\u003eTo further nourish and protect dark, color-treated hair, we’ve added provitamin B5, olive oil, honey, vitamin E and hydrolyzed wheat protein to boost softness, shine and manageability without weighing hair down.\u003c\/p\u003e\n\u003cp\u003eUse weekly or as needed after your Naissant shampoo: apply to damp hair, leave on for 1–5 minutes depending on hair porosity and desired intensity, then rinse thoroughly. The result: a cool, balanced black tone that looks more uniform, refined and salon fresh.\u003c\/p\u003e","brand":"Naissant Store USA","offers":[{"title":"Default Title","offer_id":40246679535793,"sku":"4635-9181-7207","price":17.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0580\/3366\/8273\/files\/MATIZANTESINGLESFONDOBLANCO-18.jpg?v=1763133459","url":"https:\/\/naissantus.com\/products\/black-tone-on-tone-hair-treatment-mask","provider":"Naissant Store USA","version":"1.0","type":"link"}
