I have hair with coarse tendices and I cannot do protein treatments or products with wheat germ and other proteins in the first few ingredients.

Coarse hair really doesn't need protein because it is already built-up so to speak.

I would start over with a regular shampoo, apple cider vinegar rinse and a deep condition treatment with some other conditioner like GVP Conditioning Balm.
