Hi Everyone in wonderful Advice Land!

My DD has never had a proper haircut (currently 21 months), shes had her fringe trimmed to keep it out of her eyes. Shes got gorgeous curls and DH won't let me cut it.

I was told that I HAVE to have her hair cut (by a staffer at the gym) cos its all dead hair anyway and to make it grow properly it needs cutting.

Now, DD had a bit of hair at birth but its really taken off in the last coupla months so I don't think its a growth problem but has anyone else heard of this? Do I have to get her hair cut? I was just going to let it keep growing until it becomes unmanagable.
