I've tried a few different nail strengtheners and this is by far my favourite. As other reviews have mentioned, this does seem like a long term fix and I have noticed an improvement since I have started to use this. There is no strong odour and as you massage it into the nails, it takes no time at all as you aren't waiting for it to dry.

I have very weak nails and since using this they have started to feel a little stronger, this seems like more of a long term treatment as apposed to a quick fix. I will endeavour as the results so far are much better than anything I've seen before.

My nails have always been very thin, it didn’t take much to be able to bend them, they also always looked off somehow. I’ve been using the No7 grow treatment for about a month now, 2-3 times a week and my nails are so much better! They don’t bend, they don’t feel brittle, and they look cleaner! I highly recommend this!

Love this serum. Apply it 3/4 times a week and rub into nail and cuticles. Cuticles appear less dry and nails look shinier with less splitting at the middle. Nice its not a nail polish and can be applied on top of varnish

I have never been able to grow my nails before and have tried dozens of products, all with little success. This is incredible! I will never be without it. My nails are now growing rapidly and they no longer split and flake .

Quick and easy to apply my nails are weak and this has made a difference I do not have long nails but my nails look healthier

I got this from in the Spring goody bag so thought I'd try it. My nails weren't too bad but always good to try and make them stronger. After applying twice a week for 3 or 4 weeks I noticed my nails started to go a bit brittle, now virtually all of them have broken and are very dry. Would not recommend

I was lucky enough to receive this in a gift with purchase offer when I was recently in London. Came home, removed the gel polish that I'm addicted to and started giving this a go. It strengthened my very weak and soft nails within a month of use. Highly recommended and much better than most higher priced treatments I have tried.

I have used a few products like this over the years and tbh I am not sure if they work totally or it is just that you are doing different things! I know that when I work my nails break and never grow but in the holidays they grow! It is a nice step in the routine and will continue to use.

This definitely leaves your nails feeling stronger however any nail polish I feel does the same job.
