This solution contains two patented ingredients combined with an essential oil complex to strengthen and embellish weak and stained nails.

Used on a regular basis, this solution helps to keep nails healthy looking.

Everyday, paint a thin coat of Onykoleine on each nail using the brush. Massage until completely absorbed.

Always apply on clean dry nail, without nail polish.
Use untill the nail is entirely renewed (4 to 8 month on hand nails, 6 to 12 months on toe nails).

To maintain results
 Once a week apply ONYKOLEINE® onto the nail.
