Overview
Flat, limp hair days are what amika big hit targets: a volumizing shampoo infused with caffeine to energize thin strands. Moisturizing glycerin hydrates without weight, so hair stays soft while it gains body.
Lift without the straw-like feel of many volume washes comes from pairing caffeine with glycerin. The listing skips size, ingredients beyond those two and directions, which limits comparison.
Who it's for
Fine and thin hair that falls flat by midday is the target. Dense or frizzy hair that already has a lot of body will not need the lift.
Pros and cons
- Adds volume to flat strands
- Glycerin for weightless hydration
- Soft, touchable finish
- Size and directions not listed
- Volume claim relies on the conditioner too
Performance notes
Lightweight cleansing leaves no heavy residue at the roots, which is what lets fine hair lift. Glycerin draws in moisture without coating, so strands stay soft rather than stiff.
