When my nails grew that little bit longer, they tended to break. I got this to try it and although my nails do feel a bit stronger, I'm not convinced that this product is worth the money, especially as the guidelines state it's only to be used twice a week. I'll keep using it and see if it makes more of a difference through time.

I decided out of the blue to stop biting my nails. I'm 38 and have bitten them for as long as I can remember. I knew my nails would need some TLC along the way so I decided to purchase this. It's amazing! I use it every day, not twice weekly as recommended and the results are lovely, shiny strong and healthy nails. It is fast absorbing and non greasy. I'm now onto my second bottle and wouldn't use anything else.

Nails are stronger, whiter and in general growing faster. I didn't believe it until others pointed it out!

It does what it says on the bottle..my nails are much stronger and seem to grow quicker.

I had a mini sized one if these in a No. 7 giveaway. I used it initially to have lovely healthy looking nails. Then Xmas came along and I was far too busy. My nails split, cracked, tore etc . .now after Xmas I'm back to looking after my neglected nails & the difference has been amazing. Would absolute recommend. .

This definitely makes my nails feel stronger. Such a reasonable price and No7 always have multi buy offers and vouchers in store so even more of a bargain compared to OPI etc.

I used this for a few weeks and whilst it makes your hands feel really nice it doesn't seem to be long lasting strenghth... My nails grew to a certain length then snapped as normal so I would recommend keeping your nails trimmed whilst using this product for maximum efficiency

I had high hopes for this but it didn't deliver. My nails did feel a little bit stronger after but not enough to notice a big difference. It was quick and easy to apply that's the only real positive. Sorry I would not pay the full price for this.
