The Science-Backed Nail Care Routine for Stronger, Healthier Nails
Strong, healthy nails aren't just about genetics—they're the result of consistent, science-backed care routines. Research shows that proper nail care can improve nail strength by up to 40% in just 8 weeks.
The Science of Nail Health
Nails are composed of keratin, the same protein found in hair and skin. The nail plate grows from the matrix (the area under your cuticle) at an average rate of 3mm per month. Understanding this biology helps us create effective care routines.
