My fingernails were in a terrible state lately, unfortunately I got and allergy to the hybrid and onycholysis appeared. Nails were cut short, the hand did not look good aesthetically, the nails crumbled and would not grow. It seems to me that after applying this product nails become stronger, they are harder, but does it accelerate growth? - I can not judge it, my nails have always grown fast, I did not notice that they were doing it even faster. Besides, it seems to me that the conditioner has a negative effect on the maintenance of the varnish.
