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...

Amazing Hair Serum!
I have very dry, brittle and frizzy hair which is hard to manage at times, especially in humid weather conditions. After trying Wella Ultimate Smooth Miracle Oil Serum, I was amazed at the results. It definitely does what it claims. Helped tame my hair and control frizz for a long time. You only need a little bit, and I'm sure the bottle will last me a long time. Would highly recommend.
Turned my hair into an Afro puff
Just an absolute NO!!!!!!! I have fine, low porosity, Asian hair and somehow this managed to give me a 70's style Afro puff!!!!!!! I have NEVERRRRRRR had frizz like this in my whole entire life, and have no idea how conditioner can be so insanely drying that it changed my hair texture completely!!!!!! Went back to my usual conditioner, and the Afro puff was gone. Thank goodness.
For Soft Hair
Hair Type Straight Hair
I have been using this Wella conditioner product for nearly a week now and have already begun to notice positive improvements to my hair. My hair tends to get dried out, especially throughout the winter when the air is much drier. I have used other conditioners, generally lower priced brands, and any benefit from them seems to fade really fast. However, since I have been using this product, I have definitely noticed my hair feeling softer, smoother, and healthier. Also, the feeling lasts longer than other products I've tried. Even after using in the condition in my morning shower, I still like the way my hair feels at night.
My hair feels amazing
Hair Type Wavy Hair
I used it exactly per instructions on the box, a couple drops on damp hair before styling and a drop after and my hair looked and felt amazing so soft and shiny. I wish I had know about this sooner. This is exactly what I have been looking for my dry color treated hair. I have already recommended it to friends and family and will be purchasing this again once it runs out.

Wella Professionals Ultimate Smooth Omega-9 Conditioner is the perfect second step to Wella's Ultimate Shampoo. This has transformed my hair in ways that I desperately needed. You just apply to clean damp hair all the way to the ends, leave it on for up to 3 minutes, then rinse thoroughly. My hair was so smooth that my comb went right through it with no tangle problems. It looked extremely nourished and more shinny than ever. No frizz what so ever and it looked nothing like the dull hair I had before. It left my hair super moisturized and that lasted until the next time I washed. You will love the smell of Wella. Its light and unique. It is also color safe, so no fading because of this wash. Cannot wait to try the other products in this line!
