Phytodensium is a shampoo formulated for hair that has become weak, thin-feeling, or lifeless with age — Phyto positions it for hair that has lost density and elasticity, generally past the age of 30. Its key active is a walnut seed extract used for its antioxidant, free-radical-fighting properties, paired with horsetail and birch leaf extracts included to help replenish minerals in the hair shaft, and black currant seed oil for its omega-3/6 fatty acid content.

This is a cleansing sulfate shampoo — it contains sodium laureth sulfate as a primary surfactant, along with a small amount of parabens as preservatives — so it isn't a fit if you're specifically looking for a sulfate-free or paraben-free formula.

• Massage into wet hair to build a light lather, then rinse
• Formulated for mature, aging, or lifeless-feeling hair rather than chemical-damage repair
