About this product

Sienna Naturals Lock & Seal Anti-Breakage Serum is a nourishing hair treatment formulated to repair and protect damaged hair cuticles. Designed for tight (3A–3C) and coily (4A–4C) textures, it hydrates dry ends and strengthens curls by sealing in moisture and restoring lost lipids. This serum enhances curl definition, adds shine, and reduces breakage during styling. It can be used on damp or wet hair after a leave-in conditioner, before final styling products, or as a mid-week refresh for added luster and protection.

  • 3 oz bottle size
  • For 3A–4C hair textures
