Blood Elves (and Void Elves) should be able to choose multiple colours for the hair. Why just be limited to one? If we want BLUE, and YELLOW, and RED. Let’s go for it, it looks fabulous. 
GLITTER. We need glitter, either this can be added as a feature in character customization or add a Toy item for this. It would normally only apply for 3 mins (7 days cooldown), except for Blood Elves (and Void Elves) it would last 7 days and have a 3 minute cooldown.
MORE STYLES. 
The ones we have are from 2007! Look at Kaia Gerber, Hilary Duff, Priyanka Chopra Jonas, we need more things like this.
Every race in this game has so many customization options, why can’t Blood Elves (and Void Elves) have this?
I am talking for your entire playerbase, this is for the health of the game. Please don’t let Blood Elves (and Void Elves) suffer like this.
