Refer to the following TresSher Hair Care Tips:
WASH & CONDITION
Co-wash extensions prior to installing. Wash every 1-2 weeks with sulfate-free conditioning shampoo or co-wash and rinse with lukewarm water. Deep condition every 1-2 weeks and rinse with cool water. Gently massage in a downward motion when washing, conditioning, and rinsing. DO NOT pull or tug extensions when washing and conditioning.
Use a wide tooth comb, paddle brush, or finger detangle. Lightly brush/comb extensions from the ends and work up the hair shaft.
Keep extensions moisturized with a water-based spray for curly and wavy textures and light smoothing serum for straight textures.
DO NOT use heat on a high setting or without applying a heat protectant. DO NOT use heavy styling products. This will cause build up. DO NOT comb/brush extensions excessively. DO NOT comb/brush curly and wavy textures when the hair is dry.
DO NOT dye extensions by anyone other than a professional. DO NOT dye too frequently.
Use a satin/silk hair wrap or pillowcase when lying down. DO NOT go to sleep with your extensions wet. This can cause mildew and matting.
