Lazartigue Thicker Hair Serum is a lightweight densifying serum for the scalp, made for hair that looks thinner and weaker over time. Its concentrated synergy of botanical-origin actives helps strengthen the hair at the root, so hair looks stronger, thicker and more resilient application after application. The finely gelled, non-greasy texture absorbs quickly, dries fast and goes exactly where it is needed with a glass pipette.

Key Benefits

  • Fortifies at the root: helps strengthen the hair from the root for stronger-looking hair.
  • Visibly denser hair: over the weeks, hair looks thicker, fuller and more resilient.
  • Tones the scalp: a fresh scent of mint and citrus and an energizing massage at each application.
  • Weightless texture: a fine, non-greasy gel that does not run onto the face and leaves no trace as it dries.
  • Clean formula: vegan, alcohol-free, silicone-free and free from mineral oil.

Key Ingredients

Capixyl™ pairs red clover extract with a biomimetic peptide to support the hair at the root and help counter the look of thinner, more fragile strands. Panthenol and biotin complete the vegan formula, which is made with ingredients mostly of natural origin and comes in a recyclable glass bottle.
