Fine, flat, thin, or limp hair that falls flat at the root — including chemically processed or color-treated fine hair that's prone to breakage. Not intended for thick or coarse hair, where a lightweight volumizing formula won't provide enough slip or conditioning. It's a retail, everyday-use conditioner — no salon application required.

The specific mechanism worth knowing about is Filloxane, the active ingredient in Redken's Bodifying Complex, designed to penetrate and swell the hair fiber at the cuticle rather than just sitting on the surface — that's what produces lift at the root instead of the temporary, surface-level puffiness some volumizing products give. It's also formulated to target damaged hair and reduce breakage at the same time, so fine hair that's also chemically processed gets both volume and some reinforcement from the same step, rather than needing separate products for each concern.

After shampooing, apply the conditioner and distribute it evenly through hair. Rinse thoroughly. Avoid contact with eyes; if it happens, rinse immediately. The brand's instructions don't specify a leave-on time, so a normal quick-rinse conditioning step is sufficient.

Pros: formulated specifically to add lift at the root rather than just smoothing the ends, which is the harder problem for fine hair; doubles as breakage protection for damaged hair, so it's not purely cosmetic volume; lightweight enough to use every wash without the heaviness that sinks fine hair.

Cons: because it's built for fine hair, it's likely too light to fully detangle or condition thick, coarse, or very dry hair; official instructions don't specify a leave-on time, so results depend on consistent use rather than one deep-conditioning session; volumizing conditioners generally work best paired with a matching shampoo and styling routine, so results used alone may be less dramatic.
