All our Raw hair in natural black/natural brown can be colored to 613. Since all hair is natural and can vary, some hair may be harder to lift than others. Always remember you can only go 2 to 3 levels lighter with virgin #1B hair. To go lighter will require bleaching, which should be left to licensed professionals. Colored hair should not be colored. Since the hair has already gone through one chemical process to achieve the color, treating it again could lead to undesirable results. Our advice is always to have your hair colored by a licensed professional or hair colorist. If you decide to color your hair on your own, we always recommend performing a strand test on a small section of the hair. If you need advice, give us a call or contact a professional for more help. Please keep in mind, once hair has been colored, your return or exchange is void, and we are limited in how we can help if a problem arises.
