Dubious. My nails seem to have weird bits of filmy 'skin' sticking up when I take off my polishis this what the 'growth' factor has done? It makes my next manicure much less smooth. However, my nails are strong-feeling, so this may have done its job quite well. I do not remember how my nails where back when I used my Revlon two-in-one, so I have nothing to compare it too.

This base coat is not making my nails grow any faster, but it does make them smoother and it dries very quickly, plus my polish lasted 3 days before it started to chip. Not as great as Revlon CS but hey, that's discontinued (thanks Revlon--not). It's definitely above average, and I'd definitely repurchase this.

I have stubby nails that are hard to grow. I have had this on my nails 7 days now (taken off and reapplied once) and it definitely works. My nails actually hang over my fingers now! It feels like a typical base coat when applied. It dries fast and to a clear finish. But it surprised me. I covered for my friend at his job while he went to a funeral on Wed. Knowing I'd be washing dishes for 9 hours, I applied only the Grow Faster to my nails-no color because we all know washing dishes can ruin a manicure in a hot minute. I carefully examined my nails when I got home and they hadn't chipped or came of anywhere at all. All I had to do was slap some color on and a top coat. That was impressive to me. I'll def repurchase and possibly get the Grow Stronger.

Overall, not a good product. I have been using this for about a month now and I have yet to see results. It doesn't help my nails grow faster at all, nor does it make them feel stronger. They still feel brittle and haven't grown at all, not even in 2 weeks. It's an okay basecoat, though and I'd just use it for that. I've used better products that help nails grow, I wouldn't recommend this one, especially at the expensive price tag.

I guess I'm the only one here not singing the praises of this polish. I bought it a while ago to help my nails grow, but I was never consistent with using it because of one thing: usually after applying, after a while my nails look dirty and they stain easily. I don't know what it is. In the past I've worn it as a base coat, so I never really noticed it until I started wearing it alone recently. Also, I wouldn't say that I've see an increase in nail strength or growth after using this product. I don't plan on purchasing this item again, nor will I wear it alone in the future.
