Redken Color Certification Practice Test

Lighteners come in oil, creme, and powder forms, which shows how the same lightening product is packaged and applied differently. The form you choose affects application, processing control, and comfort—oil-based lighteners glide and can be gentler on the scalp, creme lighteners give smooth, even coverage, and powder lighteners mix with developer for a strong lift and faster processing. The other categories describe branding (hair color lines), the strength or type of developer used with color (developer types), or products for conditioning after processing (conditioning products).
