Review title is Rots nails! DO NOT USE!!!! [SEP] My wife had been using this product for a few months straight in combination with a top coat gel she started noticing that are fingernails hurt if she did not have the Polish on so I urged her to clean it off and what we found underneath the nail was mind blowing.... the nails had become dark brown and extremely brittle just the slightest touch and they would snap off.... I'm not sure what kind of freaky chemicals are inside this nail polish but whatever it is, is extremely volatile<br /><br />Her entire toenail straight died and the entire thing peel off in a chunk I would not under any circumstances use this product I can't believe that it's even legal to sell it when it causes issues like that crazy stuff!!
