I had a bad renewable toenail big toe right. My horse has me unintentionally 2 times the entire nail from the nail bed .... abgequetscht..Es stand on it and slowly slid down. Not pleasant. The nail grew back, but very strange and fibrous. Since the approach of the nail bed had disappeared with the nail did certainly not from what he is to be built now .... I say yes, uncomfortable and ugly. I heard of the product and massaged over 3 months every day directly on the toe, where a healthy nail should grow and behold, now he's back there, again pretty. The materials and the oxygen can penetrate deep into the tissue, and specifically there where you want it, without being greasy long after. Highly recommended.
