Has anybody tried Renpure products on their HP? They are sulfate free and free of all harsh chemicals. I recently bought some argan oil shampoo and conditioner to try just wanted to know if anybody had used this or any of their other products and how the results were? They have a website; renpure, it's a .com website. Wanting feedback and suggestions. I know a lot of shampoos and conditioners have been covered just wanting to try something new and available locally. I've been using the L'oreal everpure in the pink tube and it works well, but the Renpure is bigger bottles and would be cheaper in the long run.
