I have always had thin, bendy, peeling nails. I couldn't grow them because they were in such weak condition. As a result, for years, I spent $$ on acrylic and then gel manicures. After my gel manicurist closed down due to Covid, I had to do something else. I found this brand - tried the primer, top coat and a couple of colors. The primer alone is the best!! I don't even use color on my fingers (only on toes) because the primer makes my nails look so nice and clean - and it somehow conditions my nails as I no longer have issues with peeling, they are thicker and stronger - and growing! I came on here to order another bottle, and decided to write a review. This is good stuff!!
