Lately, the back of my hair has been constantly tangled and frizzy. After I shampoo, it's tangled and frizzy. After I spend 15 minutes combing conditioner through my hair with my fingers and losing way more strands of hair than I think is normal, it's tangled and frizzy. And once it dries it is of course tangled and frizzy.

I'm not using any products with sulfate or silicones so what's the deal??

Btw my hair stats: 3a, coarse, low porosity, thick (I should really put this in my signature...)

Thank you!
