When washing your Maria Cabello hair extensions always begin with warm water and a moisturizing shampoo. It's important to use a moisturizing shampoo so it continues to add moisture as it cleans the hair of product build up. After you rinse the hair of shampoo, we recommend that you use a leave in conditioner for additional moisture. Allow the hair to sit for a few minutes before rinsing with cold water. Cold water will allow the bundles to retain moisture and minimize frizziness. Allow your bundles to air dry and you are all set!
