Hair dye Fail

So last night I dyed my best friends hair purple. It was the first time I ever did it and wanted to make sure it was right. I get it all done, we rinse it out, dry it, and don't see a change. She texts her friend whose a hairstylist and we realized that she has dark brown hair, and it was a dark purple.

We also forgot the lightener 😂

Everything else was good! Just forgot that lol
