ionSensitive Scalp 20 Volume Creme Developer 32 Oz

I used this in combination with Wella Powder Lightener for Blondes and the result was incredible. Don't waste your time with bleaching kits like I did, just get a bottle of this and some bleach powder and paste an ample amount of this stuff on your head. It literally lifted my hair from medium dark brown to a vibrant copper shade in 15 mins!!! The ratio of bleach powder to developer I used was 1:1.5 but it may be different for you depending on the bleach powder you use. I wanted my hair to go copper, so I didn't put toner in after, but I would recommend toner if you don't want orange/yellow tones showing up in your hair. This stuff doesn't burn the scalp by the way. It smells okay but I would still use it in a ventilated area because it is peroxide after all. Damage is very minimal (not noticeable) if you use the 20 vol. I think it's probs better to just bleach your head repeatedly over time using 20 vol rather than plaster 30-40 vol on it at once. Just use plenty of conditioner and hair oils and wash your head with shampoo less regularly than before to keep damage to a minimum.This is also a great purchase because you get a lot of product and it will last you a very long time (and save you tonnes of money).METHOD I USED:I put A LOT of product into my hair (so much so that it looked as though I was shampooing it) and my scalp didn't itch/burn/tingle at all. After I lathered the bleach in, I covered my head with cling wrap and used a hair dryer to create some heat to quicken the lightening process. This is the 3rd time I've bleached my hair and this is what I've learned:1 - Use ample product for an even result.2 - Use a comb to brush bleach into hair so you don't miss any spots3 - Start with the tips and end with the roots (roots develop MUCH faster)4 - Wrap your head up in plastic and blow dry it on a high heat setting to quicken lightening process5 - Don't wash hair with shampoo for at least a week prior to bleaching. The oilier the better!HOPE THIS HELPS AND HAPPY BLEACHING!!! :)

Gentle and great for second application to remove all the yellow.

Gentle, works well

I have waited a few months to see how I felt about changing to this developer. I do believe there is less stress to the scalp. I still feel a little "zing" sometimes, but overall less than when I use L'oreal. I tried this when my usual developer size was out of stock and feel like this one is just as good and maybe better for my scalp.

The product works very well.
