Shay Mitchell recently revealed that she was hesitant about the idea.
“I didn’t want to be a part of this at all! I don’t understand what’s wrong with Henna, why can’t we get something like that?” Shay told Refinery29. “Not because of the permanent factor, but because of it’s painful. And on your finger, it’s even more painful! So, I mean, I ended up doing it, I just held onto everybody’s hands and was sweating profusely. But, I made it.”
