Could be, but it’s headcanon either way. I’m certainly not saying lore is a proving reason for non-Void hair, just that it isn’t a disproving reason.
You can see it spilling out from her hood.
You can see my full hair, and I have no tendrils. Regardless if she has any hidden tendrils (which I doubt), her hair has a distinctly non-Voidy texture/colour.
Then I guess we agree to disagree on this. I feel VE needs to still be VE. The name and story (the little there is) is too deep to ignore the void portion.
That would be a far more compelling and valid argument if half the void elf hair options didn’t allready have no tendrils.
Waves little flag with the words “Holy Light #1” while wearing a headband that says “Forever devoted to the Light”
That hair turns into a big tendril though…
Also your profile don’t exist… armory one.
lol. you wish you where.
Here’s a picture of me:
My ponytail would glow if it was a tendril, wouldn’t it?
God I hate paladins.
not really. The lack of hair-lines define it enough.
You cannot deny my light! and my epic beard! Ya orc biggot! 
Now, no need to be intolerant of our devotion. Only cosplayers do that.

I have never been more disgusted.
just play a blef…
Don’t worry… you’ll be purged soon enough from undeath.
Why don’t you go marry the Light if you love it so much?
You light addled Draenei should lighten up.
Or I guess you’ve forgotten that death knights were among those who saved your butts on Argus?
Am I not bright enough? I can get much brighter then this! /casts wings
Argus was a matter of however “the enemy of my enemy is my friend” Kinda deal, now that the legion is gone, I shall purge the world of undead!
If Lightforged are running low on energy, are they less bright?
What do you think the tail is for?
