How long do I need to "try out" a new product on my hair before I determine if it works or not?
I always wait a month to determine whether or not a product works on my hair, because often, hair will not react well to a new routine in the beginning. Sometimes you have to give it time to get used to new products. If after a month your hair does not respond well to a product, I would stop using it. That's how I do it!
