N°.4Fine Bond Maintenance® Shampoo
Bond maintenance shampoo specifically formulated for fine hair
A variant of the No.4 shampoo reformulated for fine, low-density, or flat hair that gets weighed down by standard bond-building formulas. Cleanses gently while adding body and lift. Contains silicones (cgm_modified), but sits lighter on fine strands than the standard No.4. A useful option for fine-haired curlies (2a–3a) who want the Olaplex repair benefit without sacrificing volume.
