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...

Great serum!
Ultimate Smooth Miracle Oil Serum for Hair If your hair feels dry, frizzy, or lacks shine, the Ultimate Smooth Miracle Oil Serum might be the rescue treatment you've been waiting for. This luxurious oil serum promises to transform dull, unruly strands into silky, smooth lock and it delivers impressive results! Pros Instant Shine and Softness , Just a few drops tame frizz and add a gorgeous, healthy-looking gloss without weighing hair down. Lightweight & Non-Greasy: Unlike heavy oils, this serum absorbs quickly, leaving hair very soft rather than oily or sticky. Heat Protectant Some versions shield hair from styling tools, making it perfect for blowouts or when using flat iron. Split End Savior Smooths frayed ends temporarily while improving overall hair texture with regular use. Delicate, Luxurious Scent – Leaves hair smelling subtly fresh, not overpowering. Cons: Can Be Easy to Overapply – Start with a dime-sized amount to avoid buildup, especially on fine hair. A little bit pricey but it is worth it. Best For: Frizzy, dry, or damaged hair I have damaged hair and it works great for mine. Adding shine and smoothness to blowouts. How I Use it: On damp hair: 1or 2 pumps to detangle and lock in moisture before blow drying. On dry hair: A tiny amount scrunched through ends for a polished finish. As a pre-wash treatment: Massage into ends before shampooing for more hydration Nearly perfect!

"I received this product at a discount in exchange for my honest opinion". My hair suffers from frizz and damage that needs to be tamed. With Wella Ultimate Smooth Miracle Oil Serum I can tame my frizz for up to 96 hours it also improves the overall health of my hair. After applying this serum to my towel dried hair and styling my hair looks amazing. I like that this product not only fights frizz but it also protects my hair from heat damage up to 450 degrees. This serum is light weight and doesn't weigh my hair down. My hair looks and feels healthy and shiny. This product is a must have staple for my hair care routine.
Great shine
Hair Type Straight Hair
I am not a fan of using multiple products on my hair. I was given the opportunity to try Wella Ultimate Smooth Miracle Oil Serum and I have found my new go-to product. It was a little higher priced than what I normally use, but the few extra dollars is worth it. One use and my hair was left with a great shine and no frizz


Smooths and Smells Great
Hair Type Wavy Hair
I was not sure what to expect from this product, but I was pleasantly surprised with the outcome. With only a few pumps, I blend this into my damp hair and let it dry. It is very slippery and you need to wash your hands afterwards because of this. I do not use a blow dryer often but do curl my hair with a curling iron. It has a soft scent that you smell at first and when it dries which is pleasant. I would not say it completely controls my frizz because I have coarse, thick curly hair that is hard to manage. It does although protect it when I use hot tools and I do notice more shine to my hair that is not sticky.
Shocking results!
I have dry tangly fine hair and struggle with lots of hair breakage, this oil worked really well for me. A pump after shower (damp hair) helps to brush the hair very easily. It creates a nice sleek look once blow dried. I am very happy to have tried this product and will be using it often to create a slick, shiny and less dry hair!
