I do the gel polish at home. I have the UV light an everything. The only brand I use is CND Shellac.
I got “gel nails” once - for my wedding - and they ended up getting pulled off and ruining my nails until they grew out, but that was probably my fault as I picked at them constantly. The gel polish - at least for me - doesn’t damage my nails.
My nails last 2 weeks no matter what I’m doing. I redo them after 2 weeks because they’ve grown out, not because of damage. I can count on one hand the number of times I’ve had to re-do a nail, and I’m pretty sure that 100% of the time it was because I messed something up in the application that made it weaker. Once I broke a nail under the polish but the polish held everything together and I didn’t even realize it until I took it off later.
Putting sunscreen on your hands before a UV manicure is a good idea if you’re worried. I don’t, personally, but you certainly could.
My nails are weak and they peel and I bite them if they aren’t done. With Shellac I use bold colors because you don’t have to worry about them. I would never do my nails in such dark colors if not for Shellac.
I’ll try to take a photo pf my nails today. This polish was applied on the 7th. You can see the nail growth.
Having said all that, I am going to try the nail wraps that Emily described. I work in a hospital, though, and designs aren’t very professionally appropriate in my department, so deep colors are about as far as I can go on a regular basis.
