The Question We Hear Every Week In The Salon
One of the most common questions we hear at The 5th Element Hair Salon in Reading is: “Should I choose Wella Smooth Filler or a Keratin Treatment?”
Both treatments can improve the hair beautifully, but they are designed for different goals. The best treatment is not always the strongest one — it is the one that matches your hair type, styling routine, and expectations.
- You want a natural-looking result
- You want less frizz without losing movement
- Your hair is fine or medium density
- You want easier styling
- You do not want your hair to look dramatically different
- You want maximum smoothing
- You have thick, coarse, or very frizzy hair
- You want stronger humidity protection
- You want to reduce wave or curl
- You want longer-lasting results
“My Hair Is Frizzy But I Don’t Want Straight Hair”
This is probably the perfect Smooth Filler client. Many people do not want pin-straight hair. They simply want less frizz, more shine, easier styling, and better behaviour in damp weather.
Wella Smooth Filler smooths and refines the hair fibre while maintaining natural movement and body. The result still looks like your hair — just on its best day.
“My Hair Takes Forever To Blow-Dry”
If you spend 45 minutes to an hour styling your hair every morning, keratin may be the better investment.
A professional keratin treatment can provide stronger smoothing, faster drying, better humidity resistance, and a more noticeable reduction in daily styling effort.
“I Have Highlights And I Just Want Smoother Hair”
Highlighted and colour-treated hair often becomes porous, frizzy, dull, or difficult to manage.
Many clients do not need stronger straightening. They simply need their hair to feel healthier, smoother, and easier to control. Smooth Filler can often provide that softer, more natural result.
“I’m Going On Holiday And Humidity Ruins My Hair”
If humidity is your biggest enemy, keratin usually wins.
While Wella Smooth Filler provides excellent humidity support, keratin treatments normally offer the strongest defence against tropical climates, beach holidays, summer humidity, and persistent frizz.
What Happens If You Choose The Wrong Treatment?
Keratin When You Needed Smooth Filler
Fine hair can sometimes feel too flat, too heavy, or less bouncy than expected after a stronger smoothing treatment. The treatment may have worked perfectly — it simply was not the best fit.
Smooth Filler When You Needed Keratin
Very thick, coarse, resistant hair may improve with Smooth Filler but still not achieve the level of control expected. In that case, keratin would usually be the better choice.
The Ultimate Decision Guide
Our Honest Verdict
There is no universal winner. Wella Smooth Filler and Keratin Treatments are simply different tools for different hair goals.
If you want healthier-looking, smoother, easier-to-manage hair while maintaining natural movement, Smooth Filler is often the better choice.
If you want the strongest smoothing result possible with maximum humidity protection and longer-lasting control, keratin is usually the better option.
