Mavala Nail Care Scientifique K+ Pro Keratin Nail Hardener is a highly effective treatment for weak and brittle nails, emphasizing its use in hardening the nail plate. Its unique formula penetrates the nails, strengthening them from within. Mavala Nail Care Scientifique Pro Keratin Nail Hardener contains a scientific active ingredient that enhances the cohesion of keratin fibers, allowing the three principal nail layers to bond together. Additionally, crystal resin tears, derived from the pistachio mastic tree, are included to aid the natural keratinization process of nails, reinforcing them. This penetrating aqueous solution is neither a base nor a nail polish but serves to harden soft nails, preventing them from breaking or splitting. The formulation is especially targeted at the tip of the nail, which is considered the most fragile and susceptible to damage. With a liquid texture that is easy to apply, the hardener is quickly absorbed by the nails without leaving sticky residue. It is suitable for all types of nails, especially those prone to fragility and breakage. Scientifique K+ is ideal for individuals with weak, brittle nails or those who have difficulty maintaining healthy nail growth. Overall, Mavala Scientifique K+ appears to be designed to address the common issues of soft and brittle nails by promoting nail strength and resilience through a scientifically formulated blend of active ingredients.
