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

I’ve been using Sally Hansen Advanced Hard as Nails™ and I absolutely love it! It leaves my nails looking shiny, healthy, and beautiful—like a fresh manicure at home.Not only does it improve the appearance, but it also strengthens weak or brittle nails. Since I started using it, my nails feel much stronger and don’t break as easily. It dries quickly and works great on its own or as a base coat under polish.If you’re looking for a product that makes your nails look great and feel healthier, this is it. Super easy to apply and definitely worth it!

This is an inexpensive way to keep your nails looking great. Use is as a base for colors, then as a top coat. Your manicure will easily last a week.

This is an excellent product. It hardens nails as it claims. This product dries to a glossy finish, so if you don't want that, you can apply a different product afterward that dries to a matte finish on top.

Have used this product for many years, keeps nails healthy when you might have health concerns

Truly does make a difference in hardness of my nails. They don’t break nearly as easily. It does smell pretty bad, so I recommend opening a window when using.

Usually use OPI products, but this SH product has worked well for me. I have been pleased with it and would recommend.

So far so good. Now, if I would just quit digging in the dirt without gloves on, maybe my nails would look really good!. This is worked better than anything. I’ve tried and it certainly is a great price. It looks nice on my nails, despite the dirt!

Smells terrible (like toxic chemicals), but a solid OG top coat. I continue to buy because it dries quickly, is easy to apply, and lasts.
