The set includes four products for a complete treatment process: a Pre-Treatment Shampoo (Step 1), a Keratin Smoothing Cream (Step 2), a Sodium-Free Silk Protein Shampoo (Step 3), and a Restorative Mask (Step 4). Formulated to be formaldehyde-free and vegan, it is suitable for all hair types, including chemically treated, colored, and sensitive hair. Key ingredients include Collagen, Hydrolyzed Keratin, Avocado Extract, and Silk Protein. The system is designed to deliver extreme straightening results in approximately 20 minutes, with effects that can last up to 6 months, providing frizz-free, ultra-smooth, and shiny hair with improved manageability. The post-treatment Sodium-Free Shampoo gently cleanses while preserving the straightening effect, and the Restorative Mask, enriched with Niacinamide, Panthenol, Biotin, and Vitamin C, works to repair damage, restore elasticity, boost shine, support hair growth, and leave hair feeling soft and revitalized after a 5-minute application.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThis item is guaranteed to be fresh for at least 60 days from: 04\/09\/2026\u003c\/strong\u003e","brand":"NK Professional Care","offers":[{"title":"Default Title","offer_id":46335222677654,"sku":"E4SYDWB","price":34.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0514\/3520\/8854\/files\/tvvlepm0idbwzwdtns19.jpg?v=1775748215","url":"https:\/\/blitzstock.com\/products\/nk-4-step-keratin-hair-treatment-set-includes-shampoo-repair-mask-all-hair-types-8oz","provider":"Blitzstock","version":"1.0","type":"link"}
