schwarzkopf developer lotion

Schwarzkopf developer lotions are offered in 6 Volume (1.9%), 13 Volume (4%), and 20 Volume (6%).

They are available in full‑liter bottles (33.8 fl oz) and pocket‑sized 2 fl oz mini bottles.

Processing times listed in product details typically range from about 20 minutes up to 35 minutes, depending on the application and formula.

Some product descriptions note formulations that are gentle on sensitive scalps, dermatologist‑tested, and alcohol‑free to help preserve scalp comfort and hair integrity.

Lower‑volume developers are described as gently activating color or ideal for toning with minimal lift. Mid‑volume (around 13 Volume / 4%) emphasizes a balance of lift and color deposit. Higher‑volume (20 Volume / 6%) formulas emphasize lift, precise toning, and stronger gray/white hair coverage.
