Diamond Strength Instant Nail Hardener by Sally Hansen for Unisex - 0.45 oz Nail Hardener

I think this product is ok.. I wouldnt say it did too much in my opinion. I bought it once I probably wouldn't buy it again . I have been happy with Sally in the past but this product for me was just a little underwhelming. Im sure someone else out there might love it but for me it's just a miss on this one.

Great product to use if your nails are brittle and prone to breaking Like me But must say was inprested with it after using it for a few weeks I noticed the difference my nails felt stronger and and looked a lot lot better Sally Hansen Diamond Strength®

When I use this my nails grow fast and get hard. As long as I don't chip them on something they stay nice. You can have beautiful nails by cleaning them. I like to put this on before bed about an hour to make sure it's dry then go where I'm not touching anything till it dries.

This product was okay, but I don't think my nails responded as well to this as they do to taking additional vitamins. My nails were constantly splitting and there was a slight improvement but nothing overly major to report. Increasing my vitamins intake has been thr best thing to do

My nails can be really brittle, they snap and peel all the time and it drives me insane. I thought I would give this a go but unfortunately it didn't make much difference. Would love to find something that gave my nails some TLC and helped them grow stronger.
