thickening serum

We're not full of…

  • What: Wearing thin? This nightly, leave-in treatment fattens and fortifies over time for thicker, stronger strands and fuller hair (really).
  • Who: Those wearing thin, the fine, and the ultra-fine.

    When: Nightly. Twice-daily for the ultra-fine.

    How: Before bed, pump serum into palms 2 or 3 times; work into roots and through damp or dry hair. Longer hair types should pump again and be sure to smooth through ends.
