Our Take
The fine-hair variant of the No.5 conditioner, formulated to condition without weighing down low-density or fine strands. Provides the same bond-maintenance benefit as the standard No.5 in a lighter formula. Contains silicones (cgm_modified). A sensible option for fine-haired curlies (2a–3a) who find the standard No.5 too heavy.
