Wella Smooth Filler is a smoothing and conditioning treatment designed to reduce frizz, add shine and improve manageability — similar results to keratin, but without the harsh chemicals.
Unlike traditional keratin treatments, this is:
• ❌ Formaldehyde-free
• ❌ No harsh fumes
• ❌ No heavy coating on the hair
Instead, it works by filling and smoothing the hair cuticle, improving the hair’s condition from the inside out.
What does it actually do?
• Smooths frizz and flyaways
• Softens coarse or dry hair
Adds noticeable shine
• Makes hair easier to blow-dry and style
• Improves overall hair condition and feel
• Helps hair sit flatter and look healthier
You’ll still have movement and natural body — just sleeker, glossier, more manageable hair.
How long does it last?
• Results last up to 4 months
• Gradually fades with washing (no harsh grow-out lines)
• Can be topped up or repeated safely
Who is it perfect for?
Frizzy or fluffy hair
Dry or damaged hair
Coloured or highlighted hair
Hair that feels rough, dull or hard to style
Clients who don’t want a harsh keratin treatment
Not a straightening treatment — this is about smoothness, condition and shine, not poker-straight hair
Before:Dry, frizzy, uneven texture, hair sitting bulky and fluffy
After:Smoother lengths, reduced frizz, improved shine and a sleeker finish — without losing natural movement
⚠️ Important to note:
This treatment should not be carried out immediately after a colour service, as it may cause the colour to fade.
Best done before colouring or after allowing time for the colour to settle (Kitty will advise what’s best for your hair).
