Completely damaged and fried my hair

Saw this product on facebook. As all curly haired girls, I'm always on the hunt for the best products for my hair. I've never had an issue with dry hair, just need help with definition. I typically have to use 3 to 4 styling products. When I saw Lus brands systems I was curious enough to buy it. The first couple of times I used it, it was great, I couldn't believe it. But then my hair became damaged, dry and broken. I washed my hair once a week for 5 weeks, and havent used the products in 2 months and its still recovering.
