This stuff really does work. I have brittle thin nail that break easily. Using this nail strengthener does help. I use it as a varnish and only that but you can use it as a base coat and top coat. Highly recommend .

Didn’t know LD had this base coat out- seen on tv during flicking about! It’s really nice easy to apply. Even lovely as a base only if you are not allowed to wear polish.

My two weak nails are beginning to grow at last

Originally posted on marksandspencer.com (UK)

So far so good. My nails reach a good length then two of them start to split. They seem to be growing using this product. It does peel off easily and needs to be reapplied often though. The pink tint looks healthy.

Rock Solid nail treatment

Originally posted on marksandspencer.com (UK)

Easy to apply and dries quickly. However the product has peeled off some of my nails. Still too early to rate the long term benefits.

I normally purchase Leighton Denny base coat. With this having the strengthening treatment in it is a bonus. First time used this but the results are great.

Not as good as it used to be

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

This is the 4th bottle of Rock Solid and it has been a disappointment. My nails turned grey and the polish peeled off in one rubbery length. Also it was slower to dry. The last bottle gave me nice pink nails and did not peel. I had to use nail varnish remover to get it off as you would expect. Not good enough for the cost.

This nail strengthener is the best. After only one coat it toughens up your nails perfectly. Well worth the money.

My nails have been brittle for some time and I've tried other strengthening products without success. However, I only had to use one coat of Rock Solid to see a real difference.My nails look and feel much stronger and I will definitely be buying this product again.

Awful

Thought I would try this as it’s a good make. Awful, terrible stuff. Total waste of money. Marks so easily and it’s even worse when you put a second coat on.
