Review (5/5): What a discovery!
I never knew anything about this product but grabbed it at the store one day since I was desperate. My nails had been chipping and splitting and breaking like crazy and I was at my wits end. My nail do grow and since I work with my hands typing every day I thought I ought to be able to get decent looking nails. But noooo. They would crack and chip and flake all,the,time. This stuff is fabulous. I've only used it by itself and not with colored polish but it has completely stopped the breaking and chipping. I agree, I don't know that it is hardening my nails but it's actually protecting them and making them less porous and brittle so the breakage stops.
And I am seriously tough on my hands. I work full time, have a house, son, husband, yard and I cook, sew and craft. Plus I am a bit OCD for washing my hands and never remember to put on gloves to mess with dishes or do the cleaning. Since my nails are oddly shaped I'm constantly dealing with splitting and hangnails and breaking where I have to keep the edges filed so my nails look somewhat normal and this is no problem at all.
Now that I know it's available on Amazon, I'll be back to buy more. And I'm looking forward to trying colored polish. Since it wouldn't ever stay on my nails for more than 1 day, if I was lucky, I might actually be able to have a pretty manicure that lasts more than a few days.
