What It Is: An intense pre-shampoo treatment, rich in proteins that targets hair bonds to strengthen and repair from the inside out. What It Does: Balancing protein-rich and moisturizing products in your routine is key to strengthening and protecting the hair against damage. The more damaged and porous your hair is, the more protein-rich products you should use. Curlsmith Bond Curl Rehab Salve is an intense pre-shampoo treatment, rich in proteins that target hair bonds to strengthen and repair from the inside out. Hair is made of a keratin structure, which is reinforced by so-called hair bonds. There are 3 types of bonds that make up the hair structure: disulfide bonds, which are damaged by bleach and chemical treatments; salt bonds, which are damaged by sudden pH imbalance; and hydrogen bonds, which are damaged by excess moisture and heat. Curlsmith Bond Curl Rehab Salve is a powerful blend of superfoods and fortifying active ingredients that target all 3 of these bonds to repair, rebuild, and restore hair fiber strength. It also provides protection to help against further damage.

Free of Sulphates, Parabens, Silicones, Mineral Oils, Phthalates, DEA How to Use: Apply generously on damp hair until it is fully saturated. Leave on for a minimum of 15 minutes, (or up to 30 if you have mid-high porosity hair due to coloring, heat styling, or damage). Rinse off thoroughly and follow with your favorite Curlsmith Cleanser, Conditioner, and Stylers. How often to apply the treatment depends on your hair porosity. To find this out, spray water on clean, product-free hair. High Porosity: water absorbs immediately in the hair. Use every 2-3 wash days for 30 minutes. Medium Porosity: water forms droplets and then absorbs in the hair. Use every 3-4 wash days for 20 minutes. Low Porosity: water forms droplets on the surface of the hair. Use every 4-5 wash days for 15 minutes.
