Okay, here's the thing.

 

I was on a PvP world, running for my life (Never again am I doing that).

 

I was first killed near Al-Kharid by a member. I had the same hair.

 

Well, when I died the second time (in Karamja -- Karamja Volcano to be exact), I swapped worlds after I ended up back in Lumbridge, and I just realised when I was talking to the Woodcutting Tutor to see if he'd give me a bronze ax (instead, he wants me to give him some n_n), my hair is now in a bun instead of the dreadlock-looking style I did have.

 

Same colour, just different style.

 

What on earth caused this to happen? o.o

Hair glitches, usually resulting in baldness, has been happening for about the last six months. The barber in Falador no longer charges for his services, if you would like to get your hair changed back. He's located at the very west of the city, just north of the bank.

Oh, awesome.

 

Thanks! :)

It happened to me too during the End of Summer quest, except it happened half-way, and I didn't die \

yeah the hair glitch has happened to me too , dont worry though its common-ish

all the hair glitches have been common lately. i believe that the barber is still giving free haircuts as the person above said earlier.

my guy always gos bald you will not beileve how many times its happened
