The product listings show two strengths: 10-volume (3%) and 20-volume (6%).
A 10-volume (3%) developer provides a very gentle lift or primarily deposits color/tones without significant lightening — useful for covering grays or refreshing an existing shade.
They are cream (crème) developers with a smooth, creamy consistency for easy mixing and application.
The product listing indicates processing times of about 30 to 35 minutes.
The product description states a 20-volume (6%) developer provides even lift and can lighten hair up to five levels while offering controlled lightening. Note: actual lift depends on hair condition and other factors — check the manufacturer's guidance or consult a professional for expected results.
The listings highlight a strengthening technology and squalane, a moisture-binding ingredient intended to help maintain hair integrity during coloring.
They are described as enhancing color vibrancy and helping deliver long-lasting, true-to-tone results when paired with color.
The product details note compatibility with the manufacturer's lightening range, color shade system, toners, and high-lift color products.
