why the heck did her sisters,Bubbles and Buttercup cut Blossom's hair in "The Mane Event"?

cuz while trying to un tangle a knot buttercup accidently pulled a gros morceau, hunk of her hair out and when they tred to cover it up they cut all her hair off! :) haha

Cause she was being a chienne they got mad and cut her hair off.

because whn buttercup tried to untangle a knot she pulled her hair and they tried to cover it but instead they cut of blossoms hair=0

They didn't mean to but Bubbles and Buttercup were playing with her hair and Blossom yelled at them for playing with her hair so they started fixing her hair. Then Buttercup saw a knot so she started pulling it and half of her hair came out. Then Bubbles and Buttercup started cutting it with scissors.

It started the girls waking up Bubvles and Buttercup had lit hair a mess so to say but Blossom looked if she'd stepped out a salon not a hair out of place so she somehow let her sisters comb it but they went abut crazy turning her long hair into a racetrack with hairpins bends and a Bunny so getting pissed at her sisters Blossom demanded they give her areal hairdo so they did but her hair gor Raiponce in knots and Buttercup tried to pull out the knots breaking some off leaving a bald bit near the back so the 2 sisters panicked and desided to tidy it up saying they were trimming some divisé, split ends but wouldn't let Blossom see what they were doing but they went a bit crazy and hacked it off leaving her bald on haut, retour au début so her hair was terrible but they found it funny and everyone else and they all laughed at her it's an old episode and can be found in full online and in true animé style the following her hair was back to normal and no plus was a dit about the haircut

Because, they were amazed of blossom's beautiful long hair, and soon as she wakes up its a bad-hair jour for her, then they gave her a haircut which was totally bad-haircutted, so blossom cannot go out looking like that..

I guess because Bubbles and Buttercup were little demons who did that on purpose just to make Blossom's jour worse.
