Very easy to apply, color stays. No irritation. Quick at home application. No strong smell. Natural ingredients. The bottle last a long time. Love this product and I will be repurchasing when I’m out. I’ve been using it for over two and a half months and use it about every other week for touch up. I have two colors I mix. Leather Black and Dark Brown to get the color I like. This was recommended by my friend that has been using this for years. Love the product and I’ve recommended to others. I was truly grateful that my friend had recommended it to me. I was sent samples to try with my purchase. Looking to try the other products
