For Lightweight Silky Shine
I have fine, lackluster hair that gets frizzy and starts looking oily and limp after a day or two so I'm pretty picky with what I use. This serum oil comes in a small, travel-friendly plastic bottle with a pump. The scent is light and pleasant but I honestly prefer unscented products. It has good in...

It's okay
I was really excited to try Wella's Ultimate Smooth Miracle Oil Serum, as I've never used an oil serum before. I have long and difficult to manage curly hair, and I used this exactly as the directions say. A little definitely goes a long way (which is great, since the bottle is on the small side), b...

Amazing Product!!!!
Hair Type Wavy Hair
I really enjoyed getting to try The Ulitimate Smooth Miracle Oil Serum. I applied it right after my shower the day after I received it. I followed instructions and left it on for 30 minutes. I then blowed dried my hair and an applied a bit more after I was done. It left my hair feeling smooth and smelling so good. I noticed no frizz either!. I will honestly be looking into buying more. I definitely recommend it!


No more frizz!
Hair Type Straight Hair
After going and staying blonde, I constantly have damaged frizz that I have to deal with. This really is Ultimate Smooth, as my hair is so shiny and silky. Has a pleasant fragrance. I definitely have some family members I know would love this product and am sharing it with them as well. Everyone needs a protective oil that gives great shine!


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.
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.

Love this
Hair Type Straight Hair
I was pleasantly surprised by this new wella professionals product. I've tried a few others from their new lines and they were so so. This oil is super light weight. I have long fine thin hair and two pumps rubbed into my hands and applied was PERFECT. There was zero weigh down. It didn't look greasy. It was beautifully shiny. Looked so healthy. So smooth. It felt so soft. And smelled great. It has a hint of a warm vanilla scent. The bottle is small and a tad pricey for the size but I think since using 1-2 pumps a time it should last a bit. It does drastically enhance styling like blow drying.
