Moroccanoil Smoothing Lotion works better than other brands that offer the same.

Mon baume préféré
I love R+Co products overall, but especially this styling product. It definitely delivers moisture and shine, and is good for both blowouts and air drying. I can combine it with other styling products too, like a texturizer or volumizer. And it's nice and light for my thin, fine hair.
This is my third purchase and I will never not use another bleach. It’s absolutely amazing.
Good product, appropriate for creating natural controlled highlights in the hair, . No need aluminum foils to separate hair partitions. Creamy steady texture after mixture. Beautiful results.
Such a beautiful vibrant colour every 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.
