Ok I don't wanna gatekeep this 'cause I thought it was really cool...When I used purple shampoo on my hair today I noticed later in the day that the tips of my nails were unusually white. Like, almost like French tips white! Just thought that was a cool thing that I haven't heard anybody else point out. Idk if it's something about this purple shampoo or not, 'cause I never noticed it with other ones before. But I used the @olaplex one.
