A densifying serum built around Capixyl for progressive hair loss
Lazartigue Thicker Anti-hair loss serum is an anti-hair-loss serum for hair experiencing gradual, progressive thinning linked to age or genetics. The Thicker serum is a vegan, 90%-natural formula built around Capixyl, a biomimetic peptide complex derived from red clover that helps create the right environment for the hair follicle, supporting denser, healthier-looking hair while helping keep hair anchored as it grows. It suits all hair types, including sensitive scalps, from around age 20, with visible results generally expected after about three months of daily use.
How it works
A gel-textured serum applied directly to the scalp, absorbing without leaving a greasy or sticky residue.
Who it suits
- Gradual, progressive hair thinning from age 20 onwards
- Anyone wanting a vegan, alcohol-free hair-loss serum
- Sensitive scalps that react to heavier treatments
- A 3-month course for visible results
Worth knowing before you buy: This serum is formulated without alcohol, silicones or sulfates, and is meant for progressive, genetic-pattern thinning; sudden or patchy hair loss needs a different approach.
