Yes. FB Hair extensions can be colored. As a general rule it is easier to darken the hair than to lighten the hair. We recommend to dye darker, since it is difficult for the original colour to fade. Improper dying will ruin the hair. 

   We highly recommend having your hairdresser dye the extensions. Colouring by yourself will take a risk of not coming out the shade you want. If you can't get to a salon, please always use a good quality products and test a small sample first.
