I started using this nail hardener because my nails were soft & peeling. After a couple of weeks I could feel that my nails were getting harder & weren't peeling anymore. But just as I was praising its abilities my nails started breaking whenever they came into contact with anything; the car handle, the dryer door, the dishwasher handle. Pieces of my nail were chipping off left & right. Now they are really hard & brittle. From one extreme to the other. Oh well.
I was looking for a Bioton treatment for my nails & thought this would be perfect. This product went on more like nail polish, which had to dry before each new coat. After a couple days of wear, it had chipped off most of the nails. From the description I assumed it was an absorbing biotin treatment that would penetrates trough the nails making them stronger. Instead, my nails became more brittle, started peeling, cracking, etc. My previous half inch natural nails are now slivers on the tips of my fingers. I do not recommend this product
This product works great for brittle nails. I work with my hands a lot and my nails break and chip all the time. It adds a nice shine and I could see a difference after only a week of use.
Bought this to help strengthen my nails. I reapplied every other day for about a week and still had nails breaking and chipping, not to mention the polish just did not seem to "stay", hence the need for constant reapplication. Just not worth the money to me, although does give your nails a beautiful shine. The product I love for strengthening nails the most is OPI's Nail Envy. Wish BB would sell OPI products.
I am really hard on my nails and they are always breaking and chipping. I take Biotin Vitamin every day but it still doesnt seem to help. I bought this product and it seems to work well... When it is on the nail at least. It doesnt seem to do a very good job of actually strengthening the nail. It just provides another layer barrier to the nail while it is on. But when it starts coming off, the nail underneath is the same old weak nail :(
Nails stayed brittle after two weeks of use. Used alone and as a top/bottom coat on nails. Gives a great shine but I would not recommend for strengthening.
how effective it is just that it has formaldehyde in it. This is my fault- should've checked the ingredients before ordering. :-/
