I thought hair separated when it was healthy. That's usually how I spot healthy hair in the first place. Most of the people I know that have hair hanging as one blow dry/straighten/dye/abuse their hair.
I thought it was because a healthy cuticle will fit like a puzzle piece right next to the cuticle of the hair beside it if the cuticle is nice and flat, but if the cuticle is damaged it will be raised, so the damaged cuticle of one hair won't 'fit' with the hairs around it. If all the hairs are doing that, it ends up making one 'sheet' of hair instead of pieces that fit with each other.
I dunno
