This is our Brazilian Straight hair. When washing your hair extensions wet with warm water. Apply a moisturizing shampoo, preferably sulfate free, and use a downward motion to wash your hair. I personally use SheaMoisture Raw Shea Butter Moisture Retention Shampoo. It's a little expensive but it leaves my hair extensions soft and moisturized. Rinse out the shampoo and apply conditioner in the same downward motion.
