Peroxide & Developer
Let customers speak for us
from 3998 reviewsThis shampoo is wonderful. I have been using ABBA’s gentle shampoo for years on my very fine, thin hair, which is now white. It has kept my mid length hair shiny and healthy for years. I have tried other shampoos, even very expensive ones, over the years, when I couldn’t find my ABBA product. But none worked as well as the ABBA shampoo and conditioner. Thank you for continuing to make it available.
I've been ordering from Cosmetic World for awhile now, I'm always super impressed with how quickly I receive my order. Prices are great, they frequently have great sales - I have no complaints!
My go-to colour for a medium, cool, very ashy brown. Really does a good job of covering up any brassy tones my previously lightened hair has.
Love this line - I've used both the 7-42 and the 7-1, and I've also combined them. Both good ashy choices, with 7-1 being slightly ashier but it's not a big difference.
Verdict is still out for me; I would try this again but didn't feel the darker shade I mixed it with did a lot lot.
I've used this multiple times in conjunction with 6-12 from the same line, using the 7-1 more on my mids/ends. Always happy with the result, doesn't seem to ever go too dark even on my previously bleached mids/ends.
This has been my go-to developer for quite awhile - mixes well, bottle is huge, and the 10vol is a lot less damaging than higher strengths.
Really like these developers overall - I've used this one several times alongside the lightening powder by the same brand and always had good results.
This was nice, made my hair feel really soft - a little goes a long way, if I used too much it would weigh my hair down. Used on bleached hair so it might be pretty heavy on non-damaged hair.
I'm a big fan of Igora in general, and this colour was as expected. However, I think I'm more of a fan of the liquid semi-permanent range as I feel it's easier to use and to combine, but that's just a personal preference.
I've repurchased Olaplex No.3 several times - I often will take breaks, trying comparable, cheaper alternatives but ultimately I come back to this one. Works well for my damaged hair and IMO is worth the cost as I only use a very small amount at a time.
I've repurchased this powder a few times, I feel like its a super east-to-use + gentle lightening powder. I can just eyeball amounts and it's always turned out as expected!
This is a solid, lighter ashy blonde - I keep going back to this line for predictability, would recommend to anyone.
This is a good ashy light brown/dark blonde, I usually combine with a level 6 (putting this on mids/ends).
I like to add a splash of this to help cancel out orangey/brassy tones when colouring my hair to an ashier brown - one bottled lasts a long time.

Developer comes in different strengths, the common ones being 10 volume, 20 volume, 30 volume and 40 volume. It’s possible to buy peroxide in stronger concentrations but they’re much too strong to use on hair and should be avoided. Developer strength is sometimes represented as a percentage. 6% and 20 vol. are the same strength.
Equivalent Developer Strengths;
- 10 Volume - 3%
- 20 Volume - 6%
- 30 Volume - 9%
- 40 Volume - 12%
What strength/volume developer should I use?
10 volume is ideal for use when you don’t want the natural hair color to be lightened by the dyeing process. It’s used in toners and color glazes. These types of dyes are known as “deposit-only”.20 volume peroxide is commonly used with semi-permanent and permanent hair colors. It can have a lightening effect on natural, undyed hair of 1 or 2 shades when used with permanent color.
When mixed with bleach powder, 20 volume developer will lighten virgin hair by about 5 levels.
30 volume developer is used for lifting out color. Its main use is in bleaching and it can lighten around 7 levels depending on the bleach powder used.
40 volume is occasionally used to lighten very dark, stubborn hair as part of the bleaching process. It lightens quickly and its effects are harsher than lower concentrations. 40 volume is not recommended for on-the-scalp use. Using 40 volume developer can cause hair damage and chemical burns if not used correctly. Instead, using multiple applications using lower volume peroxide will allow more controlled lightening.
