If by everyday shea shampoo you mean the one by Alaffia, I think you should read this post:
Everyday Shea Moisturizing Shampoo from Whole Foods
(I hope I did that right
I was using their curl enhancing shampoo until I realized what saponified meant, it made my hair feel heavy, stuck together and weird. Essentially it's a soap based cleanser which is most likely alkaline. I know those who use soap bars on here do regular ACV rinses, that might help if you want to continue using it. I stopped using mine because I didn't see a benefit over using a 'regular' lo-poo.
The routine you listed is CG (I think all HE mousses are) You might want to cut out the shea shampoo and just use the sulfate poo or a lo-poo as needed. I lo-poo with shea moisture once a week, they are relatively inexpensive and have natural ingredients.
