Wella Professionals Blondor (line)

Blondor is a dependable professional lightening powder that lifts evenly and mixes predictably with standard creme developers.

Not for: First-time home users without a toner plan, and anyone with henna, box-dyed black or heavily damaged hair.

GPT 6.1 Sol · November 11, 2026

Wella Professionals Blondor Multi Blonde Powder

Versatile powder lightener with anti-yellow pigments for highlights and overall lightening when paired with the correct developer.

Not for: Damaged hair, irritated scalps, or beginners without professional guidance.

Schwarzkopf Professional BlondMe (line)

BlondMe is a salon lightener line designed for high lift with bond protection built into the system.

Not for: Anyone who only needs a level or two of lift, since a high-lift color would do that more gently.

Developer volume. Use 20 volume on or near the scalp and reserve 30 to 40 volume for off-scalp work such as balayage or foils. Higher volume lifts faster but raises scalp irritation and breakage risk.
Toning afterwards. Plan a toner for any lift that leaves visible yellow or orange. Bleach only removes pigment, and the remaining warmth is corrected by a toner, not by more bleach.
Strand test. Test a hidden section first, and always do so on previously colored or henna-treated hair. Metallic salts in some hennas and old box dye can react unpredictably or lift unevenly.
Overlap. Apply only to new growth on retouches and do not overlap onto already lightened lengths. Re-bleaching lightened hair is the main cause of breakage lines.

Why did my hair turn orange?

Dark hair passes through red and orange as it lifts, so you either need more lift or a blue or violet-based toner to neutralize the warmth.
