No problems at all. But she'll need to bear in mind that the colour will be two tones darker than the brown colour featured on the package cover.Can revlon colorsilk dye black hair?
No you must distroy the pigment first and this damages the hair anyway, but if you won't listen to advise to not do it, then go to a hairdresser and have it stripped and dyed
you need to bleach it first or else you'll barely see anythiing. bleach, use a lot of conditioner, then dye
If she's going light brown, she may need to bleach her hair first. She'd better consult a professional.
tell her to be careful she might go green or a strange red color if she is going to use this product she may need two applications
If your sister has naturally black hair, she should go get her hair colored professionally. It is not likely that the color will take. A stylist may have to lighten her hair first and then apply the color. I have dark brown hair and tried to color it. I left the color on extra long since my hair is really thick and it still did not take. My stylists says I need a two-step process. Your sister probably will as well. Besides, that is the only way she will be sure she will get the color she is going for and not something that a stylist will need to correct later. Good luck.
