Keratin 3-Day Growth, 0.55 fl oz

Amazing product which starts working almost the next day. my nails immediately felt stronger and more resilient and growth was very evident by about day 4. I use this every week in my manicure as a base coat and top coat. It dries superfast and creates a tough layer for your paint job. Definite growth in a few days if that is what you are wanting. I trust this brand to give results and it did not disappoint.

Love this ! It really did help my nails grow

Whilst wearing this nail hardening polish definitely makes my nail stronger, and less likely to break, it doesn't actually seem to improve the condition of my nails, as I had hoped. I applied two thin coats, and added another coat every couple of days, before removing, and starting again. Nails whilst painted feel strong, but once removed, the nails underneath still look and feel the same. I only purchased, and started to use it about a month ago, and maybe in time, I might notice a difference? I will update this feedback if this happens, but at the moment just need to keep my nails protected with this clear varnish strengthener.

I like the smooth application, but at £16 I should. But it does not do anything for my nails, and have been using it for a month now, so have given it a chance. Still breaking!! Not sure it helps growth or strength. I won't be purchasing this again.

I think this item is very good, leaves a nice shine on nails and feel nice and strong

Good stuff works well

Waste of money. Does not work and might as well buy a cheap clear nail varnish

I have been an habitual nail biter for as long as I can remember. At 43 years old I decided it was time to break the habit. As my nails grew back, I noticed the damage my habit had caused. My nails were in seriously bad condition. So I looked to a nail repair varnish and came across this product. It has helped immensely. True, I needed to work with my nails to bring them back with grooming tools, but this varnish has stimulated growth and has made my once brittle nails hard as, well, nails! It's a tremendous product. I've only applied twice in six weeks, but have noticed an amazing change in my fingernails after years of abuse. Highly recommend this product.

Nägel werden fester und wachsen viel schneller. Leider aber sehr teuer.

Les ongles poussent mieux et surtout plus résistants. En curatif je le mettais 1 à 2 fois par semaines et j’ai vraiment vu une amélioration que d’autres produits en boutiques n’avaient pas donné.

Me ha ido perfectamente para la uña del pulgar a la que, según mi dermatóloga, le faltaba queratina.

È super non ho mai avuto una crescita così
