I was using Malibu C Scalp Wellness, among other things. When my hair stopped falling out, I continued with vitamins and bought basic (organic) shampoo and conditioner. After 2-3 weeks, my hair started falling out again. I went back to Malibu C Scalp Wellness and the fallout stopped again. In both cases, the only thing I changed was the shampoo/conditioner. I'm a Malibu C lifer now!
