This mask isn’t just a quick fix. It’s a weekly treatment that makes your hair structurally smoother and easier to handle. Also check out the rest of the Wella SP Smoothen range for a complete routine.

1. Wash your hair as usual.
2. Squeeze out excess water so your hair is towel-dry.
3. Work a generous amount of mask through your hair, from mid-length to ends.
4. Leave it on for 5 to 10 minutes.
5. Rinse thoroughly with lukewarm water.

Using the Smoothen Mask on wash day means you no longer need a separate conditioner. Want to pamper your hair even more? Combine it with the Smoothen Conditioner. Use that on days you don’t use the mask to keep your hair soft and smooth in between.

Your hair feels softer and is easier to comb because the mask forms a smooth layer around each hair fibre. This helps retain moisture and prevents your hair from swelling in humid air. Avocado oil nourishes hair from the outside, while panthenol (a form of vitamin B5) temporarily thickens the fibre and adds shine.

As a hair mask for thick curly hair, it offers more than just hydration: it gives your hair structure and control. It also works well on unmanageable hair by tackling frizz without weighing your hair down or making it flat. A smart choice if your hair battles the weather every day.

This mask is best for thick, wavy, or curly hair that quickly becomes frizzy and hard to style. If your hair is fine or limp, this mask might feel too heavy. In that case, the Wella SP Repair Conditioner is a better pick, providing care without flattening your hair. Curious how the Smoothen Mask compares with other masks for frizzy hair?

Compared to the Wella SP Hydrate Mask, this focuses clearly on control and smoothness, not just pure hydration. And compared to premium brands like Kérastase, the Smoothen Mask is in a friendlier price range without sacrificing results. Reviews from people with thick, stubborn hair are mostly positive: calmer hair, less hassle when combing, and a softer fall.

This mask is intended for thick, curly, or wavy hair that frizzes easily and is hard to comb. If you have fine or limp hair, this mask may be too heavy, and a lighter product is better.

The mask is also suitable for coloured hair. Wella SP has been used in salons for colour and care treatments for years, so your hair doesn’t have to be untreated to benefit.

Use the mask once a week instead of your conditioner. On other wash days, use your conditioner as normal.

Want the best results? Always leave the mask on for at least five minutes before rinsing. If your hair is extra dry or damaged, you can leave it on for up to ten minutes.

Yes, this mask contains both perfume and parabens. If you have a sensitive scalp or react to perfume, it’s smart to keep an eye on this.

Wella SP Smoothen is definitely suitable for curly hair but note that the formula also contains silicones. That means the mask is not suitable for a Curly Girl routine, which avoids silicones and parabens. For everyone without those restrictions, this is no problem at all.
