My nails were very brittle after a year of having Dip powder manicures. Started using Breathable Calcium Boost to strengthen my nails and saw a difference within first week. Nails started growing and don't bend as easy as they used to...still not as strong as I would like after 2 weeks of using the product, but that will take time - Rome wasn't built in a day, and my nails are gonna take more than a week to get healthy...but they're on the right track thanks to this product. I was skeptical, but now I'm a fan!!!

Really helps build up your nails.

This calcium booster exceeded my expectations. My nails stopped splitting, and as a bonus this polished looks good and shiny. I put it on every night for several nights in a row, then remove it, and start anew.

My nails have vertical ridges, and they peel and split. I have tried tried several different products along with vitamins, and nothing seems to help. I am hoping this product is my dream come true. So far, it seems to be doing a good job.

This product had great reviews so I thought I would try it. Wasn't really expecting too much as I have been looking for just a clear polish that lasts more than 2 days.

Thru showers, washing dishes, scrubbing sinks... this polish is still on after six days. No peeling.

Truly a wonderful product. Eager to try Orly's colored nail polishes.
