What does it mean when a bottle of hair dye says do not use on relaxed hair?

This means do not add in hair if you have already used another product to remove strong curl, make it straight, or "relaxed".

Explanation:

not really sure sorry just trying to get points

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.

hope this and can i get bainliest my dude : d
