Plástica Capilar – Serum Step 4 – 250ml is the final phase of the Plástica Capilar professional treatment, formulated to seal, protect, and prolong the results achieved in the previous steps. Its lightweight texture and thermo-active action help keep the hair fiber aligned, smooth, and with a mirror-like shine, acting as a shield against the heat of hair dryers and straighteners.

This finishing serum controls frizz, facilitates styling, and provides a professional and long-lasting finish. It seals the cuticle, protects against external aggressors, enhances shine and softness, and maintains the hair alignment effect, leaving hair manageable, disciplined, and healthy-looking.
