best frizz shampoo

Review summaries most often report reduced frizz, improved softness, better curl or wave definition, and occasionally hair that appears thicker or has more body/volume.

Some formulas describe gentle cleansing while also strengthening strands: examples include improving elasticity, reducing breakage, and adding moisture or nutrients (for example, biotin-infused or protein- and lipid-supporting formulas).

Customizable bases let shoppers add targeted booster shots. For example, the curly base recommends adding an Anti-Frizz booster (alongside curl- or strength-focused boosters), and the wavy base lists Anti-Frizz among its recommended boosters.
