@ainsightx.x: Nail integrity depends on hydration, keratin structure, and microbial balance. Castor oil (rich in ricinoleic acid) helps strengthen and moisturize weak nails. Onion juice, high in sulfur compounds, may support keratin synthesis and promote growth. Tea tree oil provides antifungal activity against nail infections. For damaged cuticles, shea butter + castor oil restore the skin barrier and prevent moisture loss. Consistent use improves results. #beautyhacks #nailhealth #nailgrowth #nailfungus #beautytips
