Creating nails and hands that are truly beautiful and healthy Barielle was created over 25yrs ago, it was the very first company to devise beauty products through a treatment for horses. Grooms using a cream to treat the damaged hooves of thoroughbreds discovered dramatic improvements in their own nails as well. The formula was refined, introduced and the result was the Barielle Nail Strengthener Cream. Barielle uses safe, effective natural ingredients, none of Barielle's treatment formulas contain lye, formaldehyde, or any ingredients that are harsh.
