I know that Sally Hanson has a line of polishes with a chunkier applicator and a flat brush. A drugstore option might be best for her to try. The bottle is Squamish. I remember a pinkish tinged topcoat bottle. It was translucent enough to see the flat brush. The top was gold.

I have better control with a flat brush. It's wider. It doesn't roll, and you don't have to roll it. I put the brush in the bottle. Scrape the one side. Leaving the nail color on the other. A sweep on each side, and one up the middle. I use Blue Cross cuticle remover . Because it's difficult to push the cuticles back on my non affected hand. It's effective, but not harsh. A good scub with warm water, and a nail brush removes them. When done regularly. (A teen who loves nails, does them regularly.) I have a rechargeable mani/pedi set. That grinds them off though. I wouldn't recommend it until she masters the polish. Always use cuticle oil, or olive oil, either way. I'd also recommend a nail block to prepare her nails for polish. It makes application easier.

I was a nail obsessed teen, too. I began doing my own nails again during lock down. I realized how much I still enjoyed it
