Thank you for your responses!
I have 3a/2c in the front/top and more 2b underneath. There is really fine and frizzy hair on top but most of it is a little thicker.
As far as porosity goes...
When I slide my fingers up a hair, it is not smooth.
When I tried the float test, it didn't sink.
So maybe it is medium porosity??
When I did the vinigar rinse, it was about 1/2 cup white vinegar to 2 cups water. I only used about 1/2 a cup on my hair.
I went back and used the last drop of my Tresemme Naturals and my hair felt MUCH happier. Unfortunately, the store is completely out of Tresemme Naturals. I got a bottle of Moisture Maniac. I hope it goes well, especially since it costs 8 times more than the other!
