What is a keratin treatment?
Keratin is a natural protein – the fundamental building block of your hair. Over time, your hair loses keratin due to heat, coloring, environmental factors, and styling. The result: frizz, split ends, a rough surface, and hair that is difficult to manage.
During a professional keratin treatment, high-quality keratin is worked into the hair structure and sealed with heat. The result: smoother, silkier, shinier hair – and this lasts for several months.
Important: Keratin does not automatically mean "straight." We offer five different levels – from gentle anti-frizz to volume keratin to intensive straightening for severely frizzy hair. Together, we will find the right level for you.

The Benefits – Why Keratin?
Faster blow-drying
Keratin reduces the roughness and porosity of your hair. The result: drying time after washing is noticeably reduced – often by half. More time in the morning, less stress.
No more frizz
Keratin acts like a protective coat, enveloping and smoothing each strand. Even in rain or high humidity, your hair remains shapely and smooth.
Less split ends
The sealant repairs existing damage to the ends and protects against new split ends. Your hair stays healthy for longer – less trimming necessary.
Easier Combing
After treatment, the comb glides effortlessly through your hair – even with long or thick hair. Less tugging, less breakage, more comfort.
Fewer Skincare Products
Smooth, sealed hair structure requires less elaborate care. Instead of many special products, a sulfate-free shampoo and a light conditioner are sufficient – that saves money and time.
Environmental protection
The keratin layer protects your hair from UV radiation, heat, cold, and air pollution. Ideal before summer or after a stressful period.
5 steps. The right one for every hair type.
Together, we'll decide what level your hair needs – during a personal consultation before the treatment.

01. Consultation & Analysis
We will look at your hair, discuss your wishes, and together choose the right keratin level.
02. Deep Cleaning
Your hair will be washed with a special pre-treatment shampoo to remove residues and silicones.
03. Keratin application
The keratin product is applied to damp hair in sections – from the roots to the tips.
04. Reaction time
The keratin penetrates the hair structure. In some stages, a thermal cap supports the deep-acting effect.
05. Sealing & Finish
Your hair is dried and sealed strand by strand with the flat iron. The heat permanently binds the keratin into the hair structure.
Finishing styling, personal care tips and product recommendation for home aftercare.
No chemicals. Just pure keratin care.
Many keratin treatments on the market contain formaldehyde – a chemical that releases harmful fumes when heated and can damage the hair structure in the long term.
At MR & MRS HAJR, we work exclusively with formaldehyde-free, paraben-free keratin products. No aggressive chemicals, no health risks – neither for you nor for our team.
Our products are based on natural keratin, enriched with amino acids and plant extracts. The result is the same: silky-soft, shiny hair. The difference: your hair is nourished, not stressed.

Frequently Asked Questions about Keratin Treatment.
Jasmin, Maxvorstadt:
"The advice was honest and thorough. No empty promises, just a result that lasts. I come back every 5 months."
No – provided it is carried out professionally and with high-quality, formaldehyde-free products. At MR & MRS HAJR, we work exclusively without formaldehyde, without parabens and without ammonia. The treatment nourishes your hair instead of weighing it down.
Basically for everyone – from straight to wavy to very frizzy hair. Hair prone to frizz, chemically treated, split ends or difficult to manage particularly benefit. We will advise you personally on which of our five levels is right for you.
No. Our “Curly Hair” keratin treatment tames your curls without eliminating them. Your natural curl pattern will return once the keratin washes out. Keratin is not a permanent chemical straightening treatment.
Depending on the level, between 8 weeks and 6 months. Durability also depends on your hair care routine, washing frequency, and environmental factors. With proper aftercare, you can significantly extend the effect.
Yes – and we even recommend applying the color in combination with the keratin treatment. Since the color roughens the cuticle layer, we can completely close it again with the keratin. The color will even last longer as a result.
For the first 48 hours, you should not wash your hair, let it get wet, or use hair ties, clips, or hats. The keratin needs this time to bind to the hair. After that, you can care for your hair as usual – with sulfate-free products.
That depends on the chosen level. The Anti-Frizz level and Keratin Botox maintain or can even enhance your volume. With the more intensive straightening levels, hair may lie a little flatter, which is desirable for very voluminous hair.
Both have their advantages. Before your holiday, the keratin protects your hair from sun, saltwater, and humidity – and you'll have zero styling effort at the beach. After your holiday, it repairs the damage caused by UV and salt. We're happy to advise you on what makes more sense for you.
Once the effect wears off, you can repeat the treatment – usually every 3–6 months. There is no visible regrowth like with dyeing – the keratin simply washes out slowly and evenly.
Yes, keratin and extensions complement each other perfectly. Smoothed, sleek hair even provides a better basis for seamless extensions. We offer both – from a single source.
