No, I wouldn't recommend any chemical treatments on your easy hairstyles. However, products like hair mascara that can add subtle color shifts are perfectly fine to use! For Tape-In Extensions, you can color them just like your natural hair, but be aware that any chemical treatment can affect the quality, as they can be somewhat damaging. I recommend visiting a professional salon for your color treatment. Bring your hair extensions to the stylist to ensure a perfect color match. — Nicole, former hairdresser and CEO of Tangled.se
