Application

This is how the KERAZUL® Keratin Smoothing works:

Step 1
Wash your hair 2–3 times with the KERAZUL® Clarifying Shampoo.

Step 2
Then blow-dry your hair completely on medium heat.

Step 3
Apply the KERAZUL® Keratin Treatment evenly. Comb out any excess product from the hair with a comb.

Step 4
Leave the treatment to work for 20 minutes. This allows the active ingredients to penetrate deeply into the hair.

Step 5
While the treatment remains in the hair, blow-dry it again completely on medium heat.

Step 6
Straighten each strand 5 times with a ceramic straightening iron such as the KERAZUL® Glacé Pro.

220 °C for normal or unruly hair, 200 °C for dyed hair, 180 °C for bleached or very fine hair.

Step 7
With the KERAZUL® Smoothing Shampoo, you can now wash your hair immediately after the treatment – no waiting time needed. Use this product together with the KERAZUL® Smoothing Conditioner afterwards to enhance and prolong the smoothing effect.

Done! Enjoy smooth, supple hair for months. No styling. No hassle. Every day.

Frequently Asked Questions & Answers

What is KERAZUL?

KERAZUL provides high-quality and professional keratin products for home use.

Our keratin smoothing transforms curly, wavy, unruly hair into smooth, silky, easy-to-care-for hair without frizz for up to 3 - 4 months.

The application can be done quickly and easily at home and leads to top results in hair salon quality.

How long does the effect last?

As a rule, the effect of our keratin smoothing lasts up to 3 months.

However, the durability greatly depends on the individual hair type. Some customers report that the effect lasts up to 6 months for them. For others, it is somewhat shorter.

The effect gradually fades over time but can be refreshed and strengthened at any time through a renewed keratin treatment.

Additionally, we recommend using the KERAZUL AfterCare care products to optimally care for your hair after the keratin smoothing and to extend the smoothing effect.

Why is KERAZUL so much cheaper than a keratin treatment at the hairdresser?

At a hairdresser's, a keratin smoothing treatment often costs around €300 per application. The quality of the KERAZUL keratin smoothing is comparable to professional salon products – some hairdressers even use KERAZUL themselves or products with a similarly high-quality formulation.

The big difference lies in the costs at the hairdresser's: there you pay not only for the product but especially for the working time and the running of the salon. A keratin treatment often takes up to 2–3 hours, which causes high personnel and operating costs. Additionally, hairdressers naturally want to make a profit.

With KERAZUL, you can carry out the same high-quality treatment yourself at home – and save several hundred euros without giving up the result.

Why is KERAZUL more expensive than other products for home use?

KERAZUL is not a cheap product, but a professional product of hairdresser quality. Our formula was developed not to damage the hair, but to smooth, care for, and strengthen it for a long time.

We rely on high-quality, effective ingredients that are usually only found in professional salon products in this quality. This allows our customers to achieve results like after a treatment at the hairdresser – only at home.

While a hairdresser charges around 300 € per application for a keratin treatment, with KERAZUL you receive the same product quality for a fraction of the cost.

How long does the application take?

You can easily perform the KERAZUL keratin smoothing treatment yourself at home. If you have someone to help you, it can make the application easier – but it is not necessary.

Plan for the treatment to take about 1 to 2.5 hours. The exact duration depends on the length and density of your hair: with very long or unruly hair, it can take up to 2.5 hours, while with shorter hair you are often finished in under an hour.
