Salon Care 40 Volume Clear Developer, Maximum Lift, Stabilized Formula for Consistent, Predictable Results, Superior Gray Coverage, 16 Ounce

I've been very pleased with this purchase. The quality exceeded my expectations, and the product was exactly as described. It arrived quickly, was easy to use, and has performed well since I received it. It's a great value for the price, and I wouldn't hesitate to purchase it again. I would definitely recommend it to others looking for a quality product.

Ok so this is liquid and I use a cream tube and mixed them til I had a yogurt-like quality. Anyways it works AND YES IT'S STRONG so be professional when using it. Don't leave it too long and if 40 isn't for you, you can always dilute it with water to be 20v.

This Salon Care 20 volume clear developer works very well for hair coloring and lightening processes. It mixes smoothly with hair color or bleach, creating a consistent texture that is easy to apply evenly. The formula performs reliably, helping achieve predictable lift and good color development. It spreads well through the hair and processes evenly when used as directed, giving professional-looking results at home or in salon use. It comes in a convenient size and is a good value for frequent use. Overall, this is a dependable developer that delivers consistent performance, and I would definitely recommend it for anyone doing hair coloring or lightening.

I purchased this to remove a very old, large and intense area of stain (spilled coffee I think) on a light colored carpet as recommended by an internet source. I had tried the conventional peroxide, but it did not really work at all. This is a higher intensity solution and although it took several doses (as described in the article) it successfully removed the stains from the entire area with almost no effort.

My husband is actually using this to whiten his vintage toys (sun damage/yellowing), and it works great for that purpose! It’s strong, consistent, and does exactly what it’s supposed to. If you're into retro toy restoration, this stuff gets the job done.

I use this product remove impossible stains from carpets. I put this product undiluted into a spray bottle and brush it into my rental carpets removes dark stains on rental property carpets. I love it!!!!! I also put it into my rug shampoo machine when washing carpets. Not for use on dark carpets light carpets only. Works like magic looks like a new rug.

Great price

Its super runny. Like, literally looks like water because it doesn’t get any kind of viscosity to it until you add colorant paste to it. And it processes color (ion color brilliance brights permanent formula radiant orchid) the same as the 30vol crème developer from what i can tell so far. The azure of the same color brand doesn’t seem to like it as much as i thought it would. Kinda mixed feelings. Love the price though. Definitely beats $12 a bottle.
