About the product

What it is: Hair serum, 100 ml. Our highly effective serum protects from hereditary hair loss, strengthens the roots and redensifies for long-lasting thicker and denser hair.

What Else You Need to Know:

  • This dermatologically approved and microbiome-friendly serum strengthens roots and leaves hair feeling more bodified from the roots. It also protects the scalp from oxidative stress and restores the hair and scalp to their youthful appearance.
  • Our formula is infused with a vegan, biomimetic silk that replenishes the hair’s lost amino acids. It contains T-flavanone, known for being a powerful redensifying and anti-hair loss agent, and Ectoin, known for protecting from environmental stress.
  • For best results on fuller, denser-looking hair, use our hair thickener serum in combination with KERASILK's Redensifying Shampoo.
