Are your products safe to use on keratin-treated or color-treated hair?Updated 8 days ago

Yes, and Yes! To get the most out of your color, we suggest adding moisture to your regimen with hair goals and products. Dry hair has a raised cuticle. When the cuticle isn’t smooth and sealed, color molecules escape more easily during washing. Moisture helps seal the cuticle. Well-hydrated hair holds pigment better, so color stays vibrant longer. Apply leave-ins: When hair feels dry, apply Function of Beauty leave-in conditioner and seal the ends with Function of Beauty hair serum. 

Yes, and Yes! To make your keratin treatment last longer, avoid washing, tying, or exposing your hair to moisture or sweat for the first 48 to 72 hours. Afterward, use our sulfate-free products, wash your hair only 1–2 times a week, and utilize heat styling, as keratin is heat-activated. Apply leave-ins: When hair feels dry, apply Function of Beauty leave-in conditioner and seal the ends with Function of Beauty hair serum.
