Collagen Base + Keratin Growth + Gel Top Coat, Clear, 3 Count

Like the new product line. Have used the keratin growth before on my toes when they were paper thin from summer nail polish overload. Works really well. Use collagen for base coat.

Absolutely Amazon growth, strength too, I put one Yellow coat, one green, and two of the gel and it lasts me through work where I constantly have to wash dishes. Photos are one week apart

Great combo of strengthening polishes!

Product is excellent but brushes only go about 3/4 down the height of the bottle. I had to buy additional nail polish brushes to use the last 1/2 of the bottle. Also the brush that can me with the product was stiff and thin and didn’t lay the product down ideally. The new brushes make the product performance better because it lays doesn’t a more even coat and makes it look better dry.

Helped my nails grow long and strong

Doesn't really live up to the hype. Been using it according to instructions for a month and no change in the nails

Love this

I swear by this stuff!! No more peeling, cracking, weak nails. They grow strong and fast!!! I use faithfully. I usually do fresh clear polish every 3-5 days. I also use all 3 bottles at once. 1st coat keratin 3 day growth 2nd coat collagen maximum builder 3rd n final coat gel extreme shine top coat.

Best product ever used on my nails they grow fast and are hard and don’t crack or chip. They look so healthy

Recommended by my podiatrist when I told her that I was trying to grow out my nails after having worn acrylics for a lifetime. I use the yellow Keratin bottle every day. I also use a nail & cuticle cream. My hands are strong & beautiful. Thank you

I am 36, and I just thought I would never experience strong natural nails ever again.

The kertin nail polish works really well to help grow your nails. 2 starts lost because I can’t buy it separately anymore.
