 What's the advantage of using a one-layer color gel? Well, if you use a color gel that covers perfectly in one layer, like the color, then you actually have two very important advantages. Number one is that you use less product because you only apply one layer. So, with the same amount of ML, you will be able to do twice the amount of customers as you would do with a gel that covers in two layers. But more importantly is the second reason. And the second reason is that you will save much more time. You will apply your color, in fact, in half the time. Why? Because you only have to apply and cure once. So, the amount of time that you save will depend on how fast you work. If it now takes you, for instance, 10 minutes to apply and cure two layers of color, you can do that with a color gel that cures in one layer in five minutes, which means you can save five minutes on every client. So, that's a big advantage.
