Rated 4 out of 5 by from I would try it again L’Oréal kindly gave me this lightener for free so that I could review it. This is the first time I have used blond studio 9 L’Oréal lightener. I actually really liked it. It worked well and had an even lift.

Rated 5 out of 5 by from Quality Lightener I used this sample on a level 5/6 and the lift was great, the blond soft and shiny after, very happy with it!

Rated 5 out of 5 by from Beautiful, even lift with minimal damage It's been about 5 years since I've used Blond Studio simply because it always left the hair feeling dry no matter what, but thanks to Loreal for sending a sample I have a new appreciation for Blond Studio. Whatever reformulation they've done, it no longer leaves clients feeling like a rough ball of cotton. The lift is incredible, truly 9 shades and never leaves the hair brassy. I do prefer platinium paste for foils but will likely be switching back to Blond Studio for open air balayage clients. It has a very smooth application, still has amazing lift when mixed 1:2 or 1:3, and forms a perfect little shell around the hair.

Rated 5 out of 5 by from 9 levels Blond Studio 9 Bonder Inside Powder is a game-changer for achieving bright, even blonde results while minimizing damage. Its built-in bonding technology strengthens hair during the lightening process, leaving it feeling healthier than traditional bleach. It lifts up to 9 levels beautifully, making it ideal for dramatic transformations or subtle highlights. Easy to mix and apply, it delivers consistent results every time. Highly recommend for professionals seeking a reliable, damage-reducing lightener!

I used this on a client with fine fragile hair and was pleasantly surprised by both how well it lifted and how wonderful her hair felt after.
