So I NEVER dyed my hair, cuz I'm really scared that I would ruin it, like i Dont even use heat, my hair is just the only thing I love about me and I have a huge fear of ruining it, , would it hurt to dye it black once? Like is my hair gunna get weak?
I've dyed my hair fbeofre. It was a medium golden brown, and I've been blonde (I wouldn't recommend if you are darker haired since I had to bleach it and that is not great for your hair), red, darker browns, and black.
Maybe before going straight to black, try out a really dark brown. They have Reflective Blacks line, where it has brown tones, but is still dark.
It'll be healthier to do it if you go to a salon vs doing it yourself at home, even though dying it in general is still bad for it. However if you only do it once not enough damage will be done that it'll noticeably weaken it.
