I was initially skeptical whether this keratin treatment could do anything. But already after the first application, my hair looked beautifully smooth, soft, and above all healthy. The application was very easy and trouble-free. The instructions guide you step by step to the result.

Since I naturally have very curly and frizzy hair, this keratin straightening is almost the only solution to have less work with the damaging flat iron in everyday life. I can only highly recommend it to anyone with curls or strawier hair.

For home use, the application is top. It is just as good as a visit to the hairdresser in this regard. The time required is the same, only the costs are significantly cheaper. The effect is great, durability about 3–4 months.

My hair is usually very thick, frizzy, and tangled. Recently, I dyed it blonde and it got even worse. I am really surprised how silky smooth and soft my hair suddenly is. It also feels much healthier.

I had a keratin straightening done for the first time and wanted to do it easily at home because I recently became a mom. The application was incredibly easy. After blow-drying, all the curls disappeared and the hair feels simply fantastically soft!

My hair curls very unattractively after washing or in high humidity and looks stiff, dull, and lackluster. After using Kerazul, my hair falls completely differently and shines like never before. It looks young and healthy.
