Reveal visibly healthier nails with Kerasal Multi-Purpose Nail Repair. This nail repair uses a single formulation for multiple causes of nail looking damage, improving the appearance of fingernails or toenails damaged by psoriasis, gel manicures, aging or fungus (onychomycosis). Kerasal nail care formula contains urea with hydrating and fortifying propylene glycol to improve the appearance of your nails effectively. This multi-purpose nail repair reduces discoloration and thickness, smooths the nail surface and hydrates brittle nails with a clear and odorless formula. Unlike nail lacquer, Kerasal's breathable formula penetrates deep to provide visible results. After 8 weeks, over 90% of both nail fungus and nail psoriasis sufferers see an improvement in their nail appearance. Apply a thin layer 2x per day for the first week, once in the morning and once at night, directly to affected nail and under the free edge of the nail using the precision nail brush included in the nail kit. After 1 week, continue to apply once per day at night for a minimum of 8 weeks total. Allow a few minutes to dry after each application. Depending on the severity of the condition, 3 to 6 months of application may be needed to achieve the full effect.
