We do not recommend using any form of protein (animal or plant), bond builders, alkaline dyes, sulfate, alcohol, avebenzone, or sodium laurel sulfate products on Sierra & Sage Extensions. Due to the way our hair is processed these products will cause buildup/discoloration and will result in knotting and matting. Avoid salt water and chlorine to prevent color stripping, sleep with dry hair only in a low ponytail or braid, and brush your hair 2-3 times a day to prevent tangling and breakage. 

We suggest using hydrating and moisturizing professional grade products only. A proper home care routine for Sierra & Sage Extensions includes a extension safe shampoo, conditioner, detangling spray, heat protectant, hair mask, and hair oil. If custom coloring, use acidic based color only.
