Sally Hansen Hard as Nails

I have very weak, thin nails and this product did not work very well to strengthen them. I followed the instructions exact (apply the strengthener every 3rd day for 7 days in total, remove then repeat the process again).

I did notice on the first day (coat one) that my nails felt harder than what they did without it but by the time I added the second coat (day three) my nails didn't improve in hardness and the nail treatment started to bubble on my nails.

Using this product with the intention to solely act as a nail hardener it does not work for me but I do find it alright to use under nail varnish as a base coat.

For anyone with nails like mine (dry cuticles, weak paper think nails) I would not recommend this as a nail hardener but it is only 8.00 so it is cheap enough to have a go to see if it works for you. Worse case just use it as a base coat :)

I started using this product a few months ago, hoping to strengthen my bendy, breaky nails. I continue to use it regularly under every nail polish, hoping to see results. I continue to use it, and would repurchase because it's a smooth base coat, but I'm not quite sure if there have been any changes in the strength of my nails. Some of my nails may have become tougher, but some of my other nails are still incredibly bendy. After reading other people's reviews though, maybe it's not meant to strengthen nails which are already there but somehow make new nails strong?

This product is such a life saver! About a year ago,just before I found this product I had weak-ish nails that would always be peeling and breaking. When I found this product I used nothing but it for a while through the netball season,when my nails grew back they were much stronger and I could grow them much longer than I ever could before which was amazing. I still use this when between nail polish colours,it gives my nails a break from harsh things such as the nail polish I use that generally leaves my nails feeling weird and unhealthy. I never expected such good results from a nail product but,it really has done wonders for my nails. I could not suggest the product any more! I hardly use it anymore due to laziness but my nails stay strong from the last time I used it!

I have quick growing nails, and will often leave them long for the rare opportunities I'm able to paint them, which often isn't until school holidays. In between them, I'll use Hard As Nails to keep them from breaking during school. The product provides a nice, shiny, clear coating that definitely does what it says on the tin. However, it does wear away quite quickly, and requires a few reapplications throughout the week. I also find that it makes a good top and base coat, but usually quite dependent on the brand of nail polish underneath it. Overall, I find the product to be useful throughout times where nail polish isn't really acceptable, or just when you need a break from worrying about your colour.

As a nail biter growing my nails is a struggle! I go through stages where I give up for a while and always use Hard As Nails to help me. If you are a biter you will understand how weak your nails get when you attempt to grow them. This definitely helps strengthen them and gives them a nice sheen too. I now just need to learn to give up permanently!

I found this works for me, made my nails a lot harder and stronger, so it definitely done what it says it would do. I sometimes use it as a base coat or alone making my nails look smooth & shiny. However, I found that after a few days it starts to peel off making my nails look dry & flaky so you will need to apply regularly for the best results.

I found this product to be great at first. Gave my nails a lovely manicured look and they felt stronger! However, if you don't take it off it peels off, taking the top coat of your nail with it!! My nails were left dry and flaky. Not nice :(

It works.... not much more I need to say finally a nail hardener that actually works.

I finally have stronger nails not as hard as they could be used as tools but they aren't breaking as easy. This product is amazing,as long as your consistent in using it. I find I need to apply every few days but its quick drying. Slightly strong odor but doesn't last long.

I have always had issues with really soft nails that will split or break as soon as they get a tiny bit of length on them, so I'm always excited to try something that will give me those gorgeous, must-lusted after talons.

It's a beautiful polish that goes on well, and the smell isn't too overpowering like some of the other hardeners. While I was wearing the polish it really did make my nails a lot stronger.

The downside was as soon as I removed the polish, there wasn't really any difference in my actual nail - still quite soft and prone to splitting.

Brilliant product if you just need a hand growing your nails, however not a long term solution
