I think this question is different for us, since our hair is so delicate, it's hard to tell sometimes.
Personally, I check shed hairs after I rinse out my cowash blend.
I wait for it to dry, pull it, and it should stretch before snapping.
(When I put my fingers about an inch apart and pull, the hair should stretch about a quarter inch.)
If it doesn't stretch, I need to add moisture and assess another shed strand.
If it's too stretchy, I need to add protein and assess again.
How do you know your hair is protein/moisture balanced?
