It's much easier to apply.
I recommend you use a pair of plastic gloves. I think that it makes applying the foam better for three reasons:
1. I've noticed that when I use gloves my hair does not stick to my hand and then get pulled out. The gloves make the application smoother.
2. Your hands will not absorb the foam.
3. When you use gloves, the foam does not melt as fast as it does when your hands are bare as the gloves tend to be cooler than your hands especially if you keep them in a cool place.
