I placed an order before Christmas which I canceled for personal reasons. I contacted the company but they referred me to the website where I am not receiving any responses. They have not refunded me the money

I have been using this product for over 20 years since I started experimenting with my hair in my teenage years. It has never caused any problems to my scalp or damaged my hair. I trust it completely and continue to prefer it for every dyeing, regardless of the brand. I highly recommend it.

Very good especially for its price. I had bleached my hair and it was very weak, then I applied color and on the 3rd color I used this peroxide which I was afraid it would irritate or burn my hair because I was using it for the first time and I was wrong to be afraid! It doesn't smell too much, easy to use, the bottle is also good.

I used it with the same company's paint. The dosage instructions must be followed and it gives excellent results.

I got it to whiten some plastic parts on an old air-conditioner, so I didn't use it on my hair, just to clarify. It whitened the air conditioner perfectly, did its job well, and has a high concentration.

I have no negative comment, I use it with palette paints and so far it's great. I also like its fluidity, it's not too thick, you can easily control the amount

It opened up the natural color of my hair without being particularly troubled and they remained soft and hydrated

I used it on black hair along with koleston dye in blue shade and it had no effect.

Perfect blending without any special stirring with the paint.. smells wonderful and doesn't bother neither the eyes nor the breath!!
