Help! Bought wrong babyliss big hair

[Cristiane]

My old one went up in a puff of smoke last week. On way back from work I ran into Argos and bought the 42mm one instead of 50mm I meant to get.

Idiot.

Anyway I need to use it tomorrow, do I need to go and buy the bigger one? I have hair just past my shoulders. Will it not work with the smaller barrell?!

Just take it back, Argos will swap it.

there's not that much difference in them. I've had both.

But i only have jaw length bob.

Ah.. I wanted to use it in the morning so wouldn't be able to take it back. Just wondered if it would still work on me...
