Works Great!
I'm 49 and my hair has been through a lot. It's thinning, frizzy, and just doesn't look like it used to. I've tried so many deep conditioners and masks over the years—some were too heavy, some didn't do anything, and most just left me disappointed. I wasn't expecting much when I grabbed the Wella Ul...

The Verdict Is Still Out
I have pretty damaged hair from years of wearing it up and using a flatiron. My ends are pretty split and I suffer from flyways and frizzy hair. Thus, I was really hoping that the Ultimate Smooth Conditioner from Wella Professionals would help to repair some of the damage. While I love the smell...

Very effective and amazing fragrance
Hair Type Straight Hair
The product has a great fragrance and was very effective on my hair, the results are a smooth and shiny hair with using for 5 min in the shower. The standard packaging with no innovation on it leave the work for the product itself, great consistency and easy to apply with great results. For my straight hair, the result was a shiny and smooth texture. I would definitely reuse and keep as my regular treatment
Great for smoothing frizz on thick wavy hair
This serum worked best when applied to damp hair. It reduced frizz when heat styling and at the end of styling, which helped the blowout last longer. When applied to damp hair and let air dry, it kept my waves more defined and shiny. Applying it to dry hair didn't give me much benefit. Don't over apply or it will feel greasy and climb to your scalp meaning you'll have to wash it sooner. If you have thick long wavy hair use 1 pump to start and only from the middle to ends. I usually use 2 pumps on average.
Absolutely a miracle worker
Hair Type Wavy Hair
I absolutely love this ultimate smooth miracle oil serum! It has worked wonders on my hair. My hair is typically so dry and has a wire type texture from dying it so much. And this has actually healed my hair! Other serums only work temporary , for a day, but not this. From the first use my hair transformed from super dry, split ends, frizzy, wire type texture to soft, smooth (not frizzy) at all, and such a beautiful shine! Its absolutely astonishing how well this works. Plus for it to continue to work until my next wash (which is every 4 days. My hair is so dry I want my natural oil. I really don't have any to help get it back to healthy) I've never seen a product last that long! I definitely highly highly highly recommend this!


Surprisingly Smooth Results from a Little Bottle
Hair Type Straight Hair
t of the product. I was surprised by how much I liked this shampoo. The bottle is smaller, but you don't need a lot; a little lathers up nicely and does the job. My purchase arrived with a slight leak, but it wasn't significant, just a bit around the cap. Still, something to keep in mind, they should do something to prevent leakage. After using it, my hair felt noticeably lighter and silkier, almost like it had less buildup weighing it down. I usually always follow up with conditioner (and I did this time too), but I could still tell the shampoo alone made a difference. My hair looked smoother, felt softer, and even had a bit of extra shine compared to my previous shampoo with the same conditioner. I also like the metal purifier aspect of the product. That's not something I have ever looked for in shampoo, but it made my hair feel cleaner and refreshed, especially important if you've got hard water. Overall, this is one of those shampoos that quietly delivers if you want something that smooths, softens, and leaves your hair feeling healthy and light. That's not something I have ever looked for in shampoo, but it made my

Great Quality
Hair Type Wavy Hair
I absolutely love this serum! It leaves my hair feeling very smooth and silky without adding any weight or leaving the strands feeling greasy. I also love how much is dispensed at once because it's not too much or too little. It also smells great and adds some volume to my hair once I brush through it.
