I do not wear nail polish so can i apply a coat on top of the previous coat everyday for a week then remove and start over?

Yes that's how I use this product

Can i use this with opi nail envy

I do not know what opi nail envy is, but you can use with anyw nail polish, I use it with Essie polish . This product is great, my nails are stronger than ever, I have the best nails I’ve had in years. They are so much stronger than ever.

I use gel polish. Could i use this under my base coat. A few of my nails are not recovery well from a long illness. Is this a good option?

I put two to three coats of this and then two coats of polish.. I’m not sure about gel polish. I know that this has helped my nails grow and be srtonger.

Can I use this before applying gel nail polish on top?

I would recommend against buying this product. After several months of glue on's, I wanted to heal my nails. Sapphire peels off within a day or so. I would assume the same may happen if you apply polish on top.

BEFORE/AFTER: I ALWAYS KEEP SOME STOCKED

Two years ago, I was struggling with my nutrition and my nails used to break and crumble as soon as they grew at all, it got to the point where it wasnt just embarrassing, it was painful. Pics attached were taken literally ONE MONTH APART when I first started using Nail-Aid. I haven't had any issues with my nails since. I LOVE Nail-Aid, I have recommended it to countless friends over the years. It works better than any other product at half the price. If I break a nail from being clumsy, I just file the sharp edge and put some Nail-Aid on that nail— it grows back so quickly! If you're considering it, please, please try it! I wish I had known about it sooner!!

Peels off after 1 day

I wanted to love this product but found myself removing and reapplying every day as they would peel off! and having to use nail polish remover everyday to take them off isn't ideal as my nails are brittle which defeats the whole point of buying this products
