The Wella Professionals PRO+ Smoothfiller Demi-Permanent Treatment 500ml is a revolutionary professional salon service, designed to smooth, fill, and restructure the hair fibre in a single session. Exclusive for professional use, this demi-permanent treatment is the ideal solution for naturally frizzy hair that reacts to humidity, providing absolute volume control and facilitating daily styling in the salon or at home.
Technology and Performance
This innovative treatment stands out for its highly effective minimalist formula composed of just 8 ingredients, completely free from silicones and mineral oils. Its advanced technology works through thermal activation (using a flat iron), which stimulates the formation of new bonds within the hair fibre. As a result, hair becomes visibly smoother, shinier, and completely restructured. The anti-frizz and smoothing effect lasts up to 3 months, disappearing gradually and evenly with washes, which avoids any demarcation or visible root effect during regrowth.

Highlights, Care, or Additional Benefits
Vegan Formula: Respectful composition, dermatologically tested and developed without silicones or mineral oils.
Respect for Natural Hair Pattern: The treatment does not permanently alter the hair structure. For curly hair, it makes curls softer, less frizzy, and with a more elongated shape, without straightening them.
Colour Compatibility: You can apply tone-on-tone colour Wella Color Touch immediately after the service. Highlight services or root colour (up to 1 cm) should be performed before Smoothfiller, in the same session. For global permanent colour on the entire hair, it is recommended to wait an interval of 5 washes after the treatment.
Restriction-Free Routine: There are no mandatory waiting periods after the service; hair can be washed immediately.
Expert Tip
The professional 500 ml format ensures excellent profitability for your salon, allowing you to perform multiple frizz control and alignment services with complete technical safety. To prolong the benefits of smoothness and shine for up to 3 months at home, recommend your client to regularly use the maintenance range Wella Professionals Ultimate Smooth.
Attention: For professional use only. A detailed prior hair diagnosis is recommended before starting the process.
After hair diagnosis and consultation with the professional, wash the hair with the appropriate shampoo and remove excess moisture with a hairdryer until about 80% dry.
Divide hair into sections and apply the Wella Professionals PRO+ Smoothfiller evenly along the lengths.
Leave the product to act for the mandatory processing time of 20 minutes.
Rinse thoroughly with water to remove only the excess product.
Completely dry the hair with a hairdryer.
Begin the thermal activation phase: perform several passes with a flat iron on fine sections. This step is essential to activate the formula, seal the cuticle, and create new bonds in the hair fibre.
If you wish to perform a global permanent colour on the entire hair after the service, you must wait a minimum interval of 5 washes.
Post-service note: A slight odour may be noticed during the first few washes when the hair is wet. This is a normal and completely harmless effect that disappears completely with subsequent washes.
