Bb Wear and Care Mending Duo- Shampoo and Conditioner

I've tried a couple of B&B products before and enjoyed them, and I was looking to try a different Shampoo as the one I was using wasn't doing much for me anymore. I liked the shampoo and I feel that my hair feels more nourished and less dry and wispy. But price wise I feel that per bottle it is expensive as it doesn't lather much, and when you have long hair (like me)... I feel like the amount you get for your money could be more. I'm not against spending more for better hair care but I could go through 2 bottles in a month!
