The process begins with Fructis Keratin Sleek Shampoo, which provides intensive cleansing from the scalp to the ends, instantly smoothing the hair fiber. Next, the Keratin Sleek Conditioner complements its action, offering immediate conditioning care and making hair extremely easy to detangle. The shampoo contains a 4% smoothing complex, while the conditioner is enriched with a 10% smoothing complex, helping strengthen fragile areas and reducing hair roughness.

The third step of the care routine includes the Fructis Keratin Sleek Mask in a generous 370ml package. With an enhanced formula containing a 13% smoothing complex, this mask penetrates the hair fibers to provide intensive hydration and replenish the damaged structure of the hair. It helps tame intense frizz and unwanted volume in dry hair, delivering extra softness and a flawless look that lasts for up to three days.

The final step of the routine is completed with the Hair Smoothing Serum (50ml), which is specially designed to be activated by heat during styling. Enriched with 5% alpha-silane, the serum creates a thin, invisible protective film around each hair strand, shielding it against external humidity and the high temperatures of styling tools. Its action locks in the smooth result, preventing frizz for up to five subsequent washes.

The effectiveness of the Keratin Sleek line is based on the combination of keratin and precious argan oil (Argan Oil). Keratin rebuilds and strengthens weakened sections of the hair from the inside out, while argan oil provides rich fatty acids for deep nourishment and natural light reflectivity. All products in the set feature a 100% vegan formula, with no animal-derived ingredients, combining professional care with respect for the environment.

• Step 3: 1 to 2 times a week, apply the mask to damp hair after shampooing, leave it on for a few minutes, and rinse thoroughly. 
• Step 4: On damp or towel-dried hair, evenly apply a few drops of the serum to the lengths and proceed with blow-drying or styling with a straightener to activate the protection.
