Hair Smoothing Serum

I have been using this hair oil serum for years now, and it’s a true staple in my routine. I have a wavy hair with highlights, and I like to use the flat iron often. It keeps my hair silky, smooth and glossy without feeling heavy, and no frizz.

Great hair oil from A great brand. Keeps hair soft and tame

Miracle in a bottle omg. And smells amazing.

This is a great product. Tames frizz and smells great. I can’t give it 5 stars because the pump mechanism is a terrible design. It doesn’t even have a tube connected to the pump. I’ve purchased several bottles and I have to take the pump off every one and just pour the serum out of the bottle. I’ve wasted a lot of the serum due to the faulty bottle design as it leaked out of the bottle when it was packed for traveling. As it is quite expensive the container design is disappointing.

I’ve been using this serum for several days, and I’m really happy with the results. It leaves my hair feeling soft, smooth, and incredibly shiny without making it greasy or heavy. My hair looks healthier, feels hydrated, and is much easier to manage. A little goes a long way, and the finish looks very natural. I’ve attached real photos so you can see the results on my hair. I would definitely buy it again.

A Must-Have — I’ve Used It for Years and It Truly Works I’ve been using this hair oil for at least two years now, and it has helped my hair tremendously. Any time I run out, I notice a huge difference right away — especially at the ends. Without it, my hair is harder to brush, it loses smoothness, and it definitely doesn’t look as shiny. This serum makes my hair soft, manageable, and polished without feeling heavy or greasy. Because it’s so important for keeping my hair looking healthy, I always buy the pack of two to make sure I never run out. It’s truly become a staple in my routine. Highly recommend if you struggle with frizz or dry ends — this product really works.

The smell is absolutely disgusting. To put on your hair. It smells like frankincense, which does not belong on your hair and it doesn’t smell like a scent that GK would actually use. I’m sending it back.

Check size, don't need much but this is tiny

I have been using this serum for about 4 years now. Its very effective in terms of giving a silky look to a dry and damaged/colored hair. The smell is very pleasant and not irritating. Normally I don't like products with any type of fragrance but this one gives a nice clean feel. I recommend it to try at least once.

Great product..No doubts

This serum is excellent for coarse Afro hair and my daughter’s tight curly hair. It leaves the hair soft and silky until the next wash.
