Excellent product! It was delivered on time. I would buy again.
Me encanta
I ve been using this cream developer first time, and it gives excellent results. It mixes easily, applies smoothly, and works exactly as expected without any harsh smell or irritation. My hair color comes out vibrant and even every time.
very happy with this product, highly recommended
I have been using this hair mask for many years, I always repurchase it. I use it in place of a regular conditioner. If you have dry or damaged hair, this truly helps to deeply hydrate and repair it. My hair always feels soft, silky, and a lot more manageable after I use this. No other hair mask compares to this formula. I highly recommend it!
This whole line is really amazing. My hair was dry on the ends but using this has helped my hair recover.
Great hold and perfect size for travel.
Love this. Makes my hair, soft and manageable.
Perfeito, produto que toda mulher deveria ter, sou apaixonada
This shampoo feels so good on your scalp it tingle's in a good way .
I use it once a week to control seberotic dermatise and it works great.it can be a little drying you just have to condition well and you will be okay.
Highly recommend for seberotic dermatise.
I have been using only this cream for 2 years, as a night cream, sometimes for a day. Perfect feeling on the skin. Very-very hydrated and healthy skin. Strongly recommend!
There's a bit of a learning curve with the amount you need, which is way less than you think, the scent is pleasant a bit like tea and not over powering. Works great on my short hair.
very pleased with shipping time, good product, simple to use, thanks
I like the shampoo. It cleans my hair without stripping it. And my blonde streaks remain blonde they don't turn brassy. I will definitely be buying this again

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.
