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.

ABSOLUTELY BRILLIANT PRODUCT fixed my flaky peeling nails. Menopause nails, awful dry, couldn't grow them. Tried this and now my nails are strong and long! I am so glad I got this product. It fixed them fast too! I wish I had before pictures to show. Even the two nails that never grow have grown! Also the vertical ridges I had that were getting deeper appear to have resolved.

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
