We recommend all Dolls wash your hair before installing. Please keep your hair hydrated the entire time it is being used for a more beautiful look. For Straight hair, we recommend using a weightless oil (CEO recommendation: Biosilk Therapy Lite oil” and for curly hair, we recommend a weightless conditioner/ water combo. Hair should be properly combed/brushed daily during the entire installation. Follow these steps and you will have your Dauntless wig for years!
