My nails can become brittle so I always make sure to keep a bottle of Sally Hansen Hard As Nails on hand. This nail polish really does work and it is very affordable.

I have brittle nails so it definitely makes them harder but doesn't stay on long. I find i have to take it off & repaint every 3 days. I do use it from time to time, but formula dries out quick once opened

I've always used this nail harder. Even growing up as a kid I would buy this because I knew it would help me save the little nails I did have from breaking.

I use to use this in high school you have to use several coats to feel like it's doing it's job. Haven't tried it in my adult like. It's a great mail strengthen tho.

Sometimes I use it as top cover for my nails and sometimes when I want them plain just put it on my nails to make it shine. I am a fan of SH products for more than 10 years already. All their products are top quality !

Gave my nails extra strength to get me through. The application was easy and didn't take too long to dry. I really put my nails to the test and durability is beyond amazing.

Hard as nails Sally Hansens application technique is a quick and easy process. Follow the directions and it works. It makes your nails harder. Great value for the money.

I swear by Sally Hansen nail polish and treatments. It's what my grandmother has always used and she has amazing nails. It works and it doesn't cost a fortune. Sold!

I don't think this worked for me. My nails still chipped and peeled. It was pretty priced and smells so bad! I would make it smell less bad and stay on nails. And work for all nails. I won't re buy it

I love using this product after having several rounds of acrylic nails especially because they're paper thin! Using this product has helped me tremendously from braking any thin nails 10/10 recommend if your nails are thin like mine
