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

Superb product!

I bought this product as my nails were always weak and kept breaking and chipping. After using this twice a week I've noticed not only a difference in the strength of my nails but the growth of my nails as well. Highly recommend!

Fab product

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.

Holy Grail !

I bought this about a month ago, my nails grow out but they are very thin and my thumbnails tend to always rip on the side... so I am forced to trim all my nails down. I only used this once or twice a week for the past 3 weeks and my nails have grown out beautifully! I keep them moisturized as much as I can to avoid breaks and this product topped with some nail oil has seriously rescued my nails.

I purchased this in November 2020. Despite using rubber gloves for housework etc my poor nails were flaky and easily broken. Since using this twice a day my nails are absolutely beautiful. They look strong and healthy. I shall never be without this treatment. Its definitely the best I have ever used

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.

Strength & Growth - to recommend

Got this a few weeks ago. Nails since lockdown (March) in very bad shape. Had problems in the past, but until Spring they were quite nice. S & G helps to make even the shortest and frazzled nails look halfway decent. Sadly, the regrowth is not very strong, have to file them down and therefore no length after weeks yet. I also recommend to massage this fluid (it's not a varnish) a few times a day (not a week as recommended!) into the nail. Otherwise no result at all (was sloppy for a few days again). I guess it would be helpful to use at least a clear nail varnish over it to protect the nails. Positive is that it is not greasy, the price is reasonable and it does not smell. If the result would be faster, I would give it 5 stars.

Saved my nails

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

Great for repairing damage!

I am in a lab 9 hours a week, and we wash everything in ACETONE! Not good for your nails! This gives them back some strength when they're very damaged. They look whiter and stronger. Not sure about growing faster, but will continue to use!
