Seche Natural contains key ingredients wheat protein, calcium and polyurethane to strengthen weak nails while leaving a healthy natural finish with out a high shine. Seche Natural can be worn alone leaving a matte finish or as a base coat under polish.
I tried Seche Natural over two coats of black nail polish and I didn't like this product at all. It's as if it had some white hue I don't know if it makes sense. Instead of making my nail polish black Matt it was more of a gray Matt color, I didn't like it at all, next time maybe I will try it over lighter nail polishes.
