hello I was wondering if I have to bleach my hair or it i can just use it on my natural hair. My hair is in between a light and dark brown , but on the lighter side. I dyed my hair black before but its all out of my hair as i have shaved it all oof since then. My hair is almost shoulder length right now. Will the color still show up if I dont bleach my hair , because i dont want to bleach it as it is very healthy right now and i would like to keep it that way.

Another question is Fading , As it Fades will it start to leave a line on my head where you can see the natural color and the dyed color or will it fade all together and slowly show the natural color underneath all over. If I do bleach my hair , when the color fades will you be abe to tell that it was bleached , because once it fades I want my hair to look normal again
