I use it after every wash, each time I spray the toner in different places . ( 2-3 times a week). My hair has become stronger and falls out less in 3 months. I also feel like it's growing faster (easy to notice when you dye your hair a different color). I love the smell, it smells like mint and stays on my hair for a while. Also if you have a lot of hair loss after childbirth - highly recommended. I also bought it for my sister - her hair stopped falling out as much as before using the toner.
