Sally HansenAdvanced Hard as Nails™, Clear Nail Strengthener, Includes Retinol and Nylon, Nourishing

After 50 years I still use Sally Hansen. That means it's good 👍🏾

This has been around for decades and always worked great. It is still a great product. My fingernails started splitting so I purchased it and they already feel stronger after one coat.

Amazing product. I tried super glue and resin to help my severely cracked thumbnail and I finally found this product which did the trick. If you suffer from split fingernails, paint your nail with this to hold it together long enough for it to heal. About every 2-3 days, I added a fresh coat to my split nails (thumb nail was split almost to the cuticle), and my nails were able to fuse back together at around the 5-6 month mark. It was a journey but totally worth it.

My wife says this works for her

This is not the greatest compared to another brand I love, but it works well for the price point.

Provides a good protective later

This has really helped keep my nails firm and hard. I've noticed a major improvement in the texture as well.

Peels off too fast even w alcohol cleaning prior to use/
