Reviews about Echosline Hydrogen Peroxide Stabilized Cream 10 vol (3%)

I have been using this developer along with the hair dye from this brand for many years and everything was great. But one beautiful day, I started to have an allergy to this developer. I began to research its ingredients and compare it with other developers that don't cause allergies... It turned out that there is a dangerous preservative in its composition that can accumulate. Apparently, it remains in the hair and becomes dangerous when the hair is long. For years, I went to an ENT doctor with external otitis and unknown non-infectious itching in my ears. We didn't think it was because of the hair dye, as I didn't feel any burning or redness during application. It was only revealed through a patch test conducted properly. The doctor advises me to shorten my hair to remove the allergen and prevent further harm to my body. Now, I am also recommended to take a break from using any chemical products. I'm copying this review for all concentrations because the composition is the same.

I purchased a good developer for Londa Professional's light ash tones 12/1 and 8/81. The 3% developer worked well and added a calm dark ash shade. I achieved a nice result without damaging my hair.

I have been using this developer for many years now, and I can confidently say that it is the only one I trust. After each coloring session, my hair feels incredibly soft and remains undamaged.

I really liked it.

Perfect:)

Translation: Ideal:)

The hair becomes tangled and difficult to rinse, as if it's sticky. I thought maybe it's because of the dye, so I changed it, but the same thing happened. Brelil dye.

A good developer, just like the paint.

Excellent developer! I bought it for another hair dye, and it worked amazingly well. The measuring scale is great, and it has a pleasant scent. With a hair colorant, my hair was perfectly dyed at 3%! Special thanks to Maykap for their efficiency and service!

Everything is great with this paint from the same brand.

This is a great developer that I used with my Majirel hair dye. I am satisfied with the results and the delivery was fast. I would definitely recommend it.
