I use it like a salt shaker and sprinkle a small amount on. I peel the paper seal back half way as that controls the amount I need. You can wear a plastic glove if you don’t want to get it under your nails. I don’t wash it out for a couple of days as it’s fine to leave in. Didn’t use applicator. I do it over the bathroom sink but there is very little waste. I’ve told my hairdresser who is going to get it for her mother. Thankyou for this wonderful product. God Bless .H.K.
