I recently switched to Aussie Sun-Drenched Shine shampoo and conditioner, and my hair is so soft and smooth and shiny now. BUT, I've noticed that soon after I made the switch to Aussie, I've been plucking out a lot more grey hairs then ever before (I'm only 24). I'm not sure if it's because of the Aussie shampoo/conditioner, or if it's because of the increased stress this school term (in my final year of university). Has anyone ever had this problem with Aussie?
