Do you mean BIAB? I use it and I’ve never had a problem. They don’t break and my nails feel good.

I've used this on my nails now for a few months and they've not split once!

Previously, my nails were always breaking, but since having the BIAP treatment, they've become much stronger.

However, I do worry about catching a nail on something hard, as they feel so rigid, I'm frightened I'll tear my nail off!

All in all, my nails are stronger, which I'm hoping is a good thing.

Has anyone on this site used BIAP on their nails. Mine and they are getting very weak from Shellac, flaky and thin.  The nail technician where I get my hair done has previously suggested BIAP - she sold it as 'nail in a bottle'! but I don't want to make them worse so thought that I would ? 

Would love to know if it helps or hinders!
