Initial Impressions & Product Overview
I decided to try Wella Professionals Blondor Multi Blond lightening powder for the first time. My hair had significant regrowth, and I was aiming for a pale banana yellow base. The product would be used with a 40 volume developer, a combination I hoped would lift seven shades.
I've bleached my hair before, but this was a new product, so the results were uncertain. I had a previous tutorial on bleaching hair, which I'll link for anyone interested in the process itself. This review focuses solely on the results and experience using this specific bleach.
The Bleaching Process & Hair Background
My natural hair color is very dark brown, bordering on black. I typically use a blonde dye to extend the time between root touch-ups, blending my natural color with highlights. This pre-existing color presented a challenge, as dye not only lifts but also deposits color, potentially making bleaching more difficult.
I applied the bleach as highlights, focusing on my roots. The mixture was two parts peroxide to one part bleach powder – a ratio I consistently use. I used a significant portion of the product; hopefully, a single application would suffice.
Processing Time & First Impression of Results
I left the bleach on for 40 minutes under a shower cap to expedite the process. Typically, I need two bleaching sessions to achieve my desired pale yellow. I wasn’t sure if one application would be enough with this product.

After washing out the bleach, the results were promising! The roots were a fairly light, slightly warm yellow. The ends that I bleached last were slightly more yellow, possibly due to a slower application there.

Final Verdict & Conclusion
Overall, I'm highly satisfied with the Wella Blondor Multi Blond lightening powder. It achieved a significantly lightened base in a single application, requiring minimal effort. The slight warmth in the yellow tone is easily correctable with a toner.

Considering its effectiveness and the minimal number of applications needed, this bleach is a good option for those aiming for a light blonde. I would definitely repurchase and recommend it. I’ll share a follow-up video on the toning process.
