Shedding...

Ok so Cam is shedding like a mad woman & hair is EVERYWHERE!
I just got Digi's shedding under control as she now allows me to brush her, HURRAY!

But Digi's brushes are terrible on Cam. They either get nothing, or it takes me a yr to do 1 tiny spot as the brush fills the second it touches Cam.

Cam is a med hair Persian/Tabby. Her fur is very light, soft & semi course.. if that makes any sense.

You can see the fur falling off her as she walks around. yes its that bad hahaha
My face is always covered in hair when I go near her, so my eyes puff up pretty quick as I'm allergic to her (don't care)... My allergies are fine until her floating twins attacks my face

Help?
Advice?
