Overview
Not a heavy volumizing spray, this MONAT shampoo builds the look of thicker hair at the wash stage with Capixyl, pea extract and a blend of plant oils. Rosemary and mint scent the formula, which skips sulfates, silicones and parabens.
A sulfate-free base with Capixyl and plant oils aims at fullness without stripping. Size figures conflict, and no clinical numbers back the thickening claim here.
Who it's for
People with fine, limp or damaged strands who prefer vegan, sulfate-free care get a fullness-focused wash. Those with heavy hair loss should see a doctor.
Pros and cons
- Sulfate and silicone free
- Capixyl and pea extract
- Long free-from list
- Rosemary mint scent
- Volume figures conflict
- Growth claims not quantified
- Specs list damaged hair only
Performance notes
Fullness comes from strengthening each strand from the roots, and a silicone-free formula leaves nothing heavy behind to flatten lift. Plant oils and omega fatty acids condition, and results depend on regular use.
