The OnyxoGuard Nail Growth and Repair Serum (also spelled Onyxo Gurad on some packaging) is a 15ml topical treatment formulated to target brittle, damaged, and weak fingernails or toenails. 

The serum relies on a blend of hydrating compounds and botanical extracts: 

• Biotin (Vitamin B7): Promotes protein synthesis to build nail thickness and minimize cracking.
• Centella Asiatica Extract: Soothes and conditions the delicate skin and cuticle matrix surrounding the nail bed.
• Collagen & Dextran: Deeply hydrate the nail layers to restore natural elasticity, smoothness, and shine.
• Aqua: Provides the fluid base needed for quick nutrient absorption. 

• Combats Onycholysis: Formulated to aid in treating the gradual separation of a nail from its pink nail bed.
• Strengthens and Hardens: Reinforces the structural integrity of thin nails frequently damaged by manicures, acrylics, or health conditions.
• Accelerates Growth: Feeds essential vitamins directly to the nail matrix to encourage faster, healthier regeneration.
• Deep Moisturization: Hydrates dry, flaky, or peeling nail plates to prevent splitting. 

To achieve optimal results, follow these usage guidelines: 

1. Cleanse: Wash your hands or feet thoroughly with warm water to soften the nails, and clear any dirt from the surface.
2. Apply: Brush a uniform, thin layer of the serum directly onto the affected nails and the surrounding cuticle area.
3. Massage: Gently massage the liquid in circular motions until it is completely absorbed into the skin and nail plate.
4. Frequency: For the first week, apply twice daily (once in the morning and once at night). Reduce application to once daily thereafter as maintenance.
