Mavala Scientifique K+ Nail Hardener

£8.95 - £14.89

Strengthens and hardens nails to reduce breakage and flaking

Available in 2ml and 5ml sizes.

Free from formaldehyde, Mavala Scientifique K+ Nail Hardner quite simply makes your nails stronger. The hardener penetrates the nail plate so that nails can return to normal growth, whilst strengthening the tips and preventing flaking.  Keratin and natural crystal resin tears drawn from the pistachio tree are included in the formula. These ingredients improve the cohesion of the keratin fibres in your nails and so help them to become more resistant to breakage.
