Smoothing and regeneration in one step

Keratin not only straightens, it fills gaps in the hair structure and rebuilds the cuticle.

Effects up to five months without repeating the treatment

Keratin straightening lasts long – without the need to use a straightener every day.

Works on all types of curly hair

From light waves to tightly curled strands – we select the concentration of the preparation depending on the degree of waving.

After the treatment, the hair is lighter and more manageable

Frizz, static electricity and tangling disappear – your hair styles faster and effortlessly.

Keratin from the inside – how does it work?

Keratin hair straightening is a treatment in which a keratin-based preparation—a protein that builds the natural structure of hair—penetrates the cuticle, filling in gaps and smoothing the hair from within. The result is not just straightening but also actual structural repair. Hair becomes smooth, shiny, and much easier to style.

We recommend a keratin hair treatment primarily for curly, wavy, and frizzy hair. It also works well on thin, damaged, and discolored hair—keratin evens out porosity and seals the cuticle. We do not perform this procedure during pregnancy or breastfeeding. We also advise against it if you have active scalp changes or irritations—a prior consultation is necessary.

The price of keratin hair straightening at our Warsaw salon depends on the length and density of the strands. The price for a specific keratin hair straightening option is determined during a consultation after assessing the condition of the hair, not in advance.

The keratin treatment contains keratin, amino acids, vitamins, and plant oils. These ingredients work on both the outer layer of the hair and the inner cuticle, resulting in deeper and longer-lasting results than with standard thermal smoothing. After smoothing, the strands are protected from UV radiation, chlorinated water, and sea salt.

Keratin straightening is priced based on the duration of the procedure—two to four hours depending on the length and density of the strands. After the treatment, avoid getting your hair wet or tying it back with a hair tie for a few days to ensure the results last longer.

If you’re also planning a coloring treatment, keratin can be combined with dyeing—we’ll discuss the order and interval between treatments during your consultation. Details can be found in section dedicated to coloring and dyeing.

Keratin treatment treats hair comprehensively – but if you are looking for lighter options for hair restoration without straightening, it is worth checking out other regenerative treatments available in the salon.

Keratin step by step – from cleansing to effect

Washing with a special cleansing shampoo

We remove any cosmetic residue, silicones, and grease from the strands. Deep cleansing is essential for even keratin penetration—without this step, the product will work unevenly.

Application of keratin preparation

Apply liquid keratin section by section to slightly dried strands. Select the product based on the degree of wavy hair and hair condition—different concentrations for thin strands and thick, curly strands.

Drying and pre-smoothing

We blow-dry the hair to activate the ingredients. The strands will gradually begin to smooth out—a step that prepares the structure for the final keratin seal.

Ironing with a straightener

We iron each strand at a high temperature—this step "drives" the keratin into the hair cuticle and seals the cuticle. The temperature and number of passes depend on the thickness and porosity of the strands.

Effect evaluation and correction

We check the smoothness of the finish and, if necessary, touch up any areas that didn't absorb the product as well. This is our last chance to even out the effect before rinsing.

Rinse and final recommendations

We rinse off excess product and apply an acidic conditioner to balance the pH. We discuss home care—sulfate-free shampoo, no tying for the first few days, and when to return for a follow-up appointment.

FAQ

How long does the effect of keratin straightening last?

When using sulfate-free shampoos, the effect lasts three to five months. The sulfate in shampoo accelerates the leaching of keratin—this is the main factor that shortens the effect.
Is the procedure suitable for colored hair?

Yes, keratin seals the cuticle and can enhance color after dyeing. The order of both procedures is important—we discuss this during the consultation before booking your appointment.
How much does keratin straightening cost in PIED-DE-POULE?

The price of keratin straightening depends on the length and density of the strands. We provide a quote after the consultation—before the appointment, not during it.
Can I wash my hair normally after the treatment?

For the first 3–4 days, don’t wet or tie your hair up. After that, use a sulfate-free shampoo and a regular moisturizing mask—this will prolong the results for several weeks.
Is the procedure safe for very damaged hair

Yes, keratin regenerates and strengthens damaged strands. The only contraindications are active scalp irritation, pregnancy, or breastfeeding. In doubtful cases, we assess the condition of the strands during a consultation.
