To understand why your hair might not be taking color, we need more information! Please tell me:
* What color are you trying to dye your hair?
* What type of dye are you using? (permanent, semi-permanent, temporary, etc.)
* What is your natural hair color?
* Have you dyed your hair before? If so, what color was it?
* Have you done anything to your hair recently? (like bleaching, perming, or using heat styling products)
Once I have this information, I can help you figure out why your hair might not be taking color and what you can do about it.
