Finishing hair mask Profkeratin Bioplastia (step 4)
Profkeratin Bioplastia finishing hair mask (step 4)
The concluding rinse-out mask of step 4 in the Bioplastia program — nourishes, smooths the cuticle and seals restored fibers. Formulated with keratin, collagen, shea butter and hyaluronic acid.
The final rinse-off mask Bioplastia 4 by Profkeratin is the concluding step of the four-stage hair restoration system. It locks in the results of the previous steps: nourishes, smooths the cuticle, and imparts silkiness, shine, and an anti-static effect. Suitable for natural, color-treated, bleached, and chemically damaged hair.
Key Benefits
- Smooths and seals the cuticle, delivering mirror-like shine and increased density.
- Nourishes the cortex from within — replacing dryness and brittleness with softness and elasticity.
- Anti-static effect and frizz control for porous, tangled hair.
- Results are visible after the first treatment and intensify over a course of 3–7 applications.
Composition / Active Ingredients
- Hydrolyzed keratin and hydrolyzed collagen — restore the hair structure from within.
- Shea butter (Butyrospermum Parkii) — intensely nourishes and softens.
- Argan oil (Argania Spinosa) and macadamia oil — restore the lipid layer of the cuticle and add shine.
- Hyaluronic acid and panthenol — moisturize and strengthen the hair fiber.
- Tocopherol (Vitamin E) — protects against oxidative stress and environmental damage.
- Aloe vera extract and plinia extract — soothe and nourish.
How to Use
Apply the mask to clean, damp hair after completing the first three steps of the Bioplastia treatment. Distribute evenly from roots to ends, leave on for 5–10 minutes, then rinse with warm water. The treatment is recommended as a course of 3–7 applications at a frequency of once per week.
