How long do you cure CND Shellac polish in a 36-watt UV light if you don’t have a CND lamp?


CND lamps are designed to give a proper cure to CND products. There isn’t a time that can be given for other lamps that will ensure a proper cure, as they haven’t been lab tested. LED lamps put out a higher concentration of UV in a more specific band so it would need to be the precise band Shellac products would need for curing. Don’t just take my word for it though! Visit for scientific evidence and information on UV and LED lamps.

How can I prevent lifting when my client's hands are constantly in water?

I have a client who is in the medical field so her hands are constantly in water. She has me keep the length of her acrylic nails short. No matter what I do, she always has at least one nail that comes off, and she always has lifting and gets water under the acrylic. I prep the nails correctly, I have a cuticle bit to clean the cuticle area, and I wipe the nail with alcohol, dehydrate the nail, and prime the nail. What should I do?
