Large sizes and a scalp-first approach suit people committed to a thinning hair routine. The bullets also describe a separate treatment, which makes the contents unclear.

Performance notes
Removing sebum and buildup from the scalp lets hair lift at the root, which reads as fuller. Conditioning agents strengthen strands, so less breakage preserves more length and density.
