Rated 5 out of 5 by brianna from I love this! i am m obsessed with the consistency of this developer! The oil-powered formula is a total game-changer for maintaining hair integrity while achieving that perfect, clean lift. It mixes like a dream and leaves the hair feeling hydrated and looking expensive—which is exactly what my 'baddie' clientele expects. If you want a seamless, high-glam finish with maximum shine, this is a staple for your backbar. 10/10 recommend for my fellow blonde specialists!"

Rated 5 out of 5 by Nadine from Good This is hands down one of the creamiest lighteners I’ve worked with, and the application is so smooth and effortless. It spreads evenly through the hair, giving a consistent lift from root to ends, and I noticed it processed faster than others I’ve used before. The performance really impressed me, and it made the entire service feel more efficient. I’ll absolutely be adding this to my regular rotation. I received this product complimentary in exchange for my honest feedback.

Rated 4 out of 5 by Bethany from Love’ I’ve been really happy with the BlondeMax 20-Volume Oil-Powered Developer. It mixes smoothly with the lightener and gives a nice creamy consistency that’s easy to apply without dripping. I noticed it helps lift evenly and keeps the hair looking bright without getting overly brassy. What I like most is that it feels a little more gentle compared to some traditional developers, probably because of the oil-powered formula. My hair still felt soft after rinsing, and I got consistent results from roots to ends. Overall, this is a dependable developer that works great with the BlondeMax system, especially when you want controlled lift without unnecessary damage. Definitely one I’ll keep using.
