Formulated specifically for fine, flat, or thin hair that loses volume and body over the course of a day, not marketed as an all-hair-types shampoo. It's suited to everyday use as a regular shampoo step for anyone whose hair needs help holding lift at the root, and it's sold in both professional salon sizes and smaller retail sizes for home use.

Fine hair typically goes flat because conditioning agents and oils build up at the root and weigh strands down, so this formula keeps the cleansing base light and uses Filloxane, a bodifying polymer, to add lift instead of leaning on heavier moisturizers. The result is a shampoo engineered around one specific hair complaint, limp and flat fine hair, rather than a general-purpose cleanser, which is worth knowing if your hair type isn't fine to begin with.

1. Apply to wet hair
2. Massage into a lather at the scalp and through the lengths
3. Rinse thoroughly, then follow with a lightweight, volumizing conditioner

The trade-off here is a familiar one for volumizing shampoos: strong cleansing power in exchange for lightness.

• Noticeable root lift and body from the Filloxane-based Bodifying Complex
• Lightweight, non-greasy rinse-out that won't re-coat fine hair
• Available in multiple sizes for salon or home use

• Formulated with sulfates (Sodium Laureth Sulfate, Sodium Lauryl Sulfate) as primary cleansers, a consideration for anyone avoiding sulfates on color-treated or chemically processed hair
• Not designed for coarse, thick, or dry hair that needs a richer, more moisturizing cleanser
• Redken does not market it with any specific UV-filter or color-fade-protection claim
