Great product, good price. Worth trying.
I purchased this product to try the hair oil since I’m super picky about oils on my hair. I was looking for a replacement for the oil I’ve been using which hasn’t been hydrating enough with the winter weather.Although the product amounts are super small, they are large enough for you to try and see if you like them for your hair. I already knew I loved the leave in hair mask but had never tried the lightweight repair oil. For reference, I have super thick, dark brown hair that falls at my waist. The oil is extremely lightweight but does a great job of hydrating my ends – which are long overdue for a trim. It helps me extend time between washes since my ends look hydrated without looking greasy.I would definitely give this a try if you don’t want to commit to the large expense of the bigger bottles.

100% worth the price!!
This stuff has absolutely saved my hair. I’m a huge fan of the K18 mask to start with and after going a little too hard while touching up my blonde highlights my hair was in major need of repair. I got this as it had the oil included and OH MY GOD can you tell the difference. Both of these products are absolute powerhouses! If your hair has any damage at all or is in need of moisture I can’t recommend it enough! Definitely expensive but worth it.

One drop
I’m honestly blown away by this K18 hair oil. One single drop is enough to smooth my frizz, add shine, and make my hair look like I just walked out of a salon. It’s super lightweight, not greasy at all, and somehow still makes my ends look healthier instantly.

Great for shine on blonde hair
I tried out the traveler size first before committing. I’ve been using the product for over a month, and it keeps my hair soft after blow-drying/blowout. Definitely felt the difference in how healthy my hair feels because I tried the garnier fructis as a “replacement” product for those two days my hair was dry, frizzy, and no shine. My husband noticed how shiny and bright my hair was right away when I started using the K18 oil again.

Great for hydrating hair
It makes my hair look healthy, especially if my hair is super dry. The scent is fantastic! It makes my hair very soft, but use as little as possible, or else it will be super oily. The dropper makes it so easy to use, with dispersing too much product.I will say, it is very expensive for the amount you get. When they say it’s travel size, it sure is.I have thin hair, so I only need a little bit.

Subtle Scent, Serious Letdown – Left My Hair Drier Every Time
Give it three stars because so many people love it but personally I think it’s horrible especially for people with over processed hair and I had high hopes for the K18 Molecular Repair Hair Oil. With all the buzz surrounding this sleek, science-forward brand and the premium price tag, I expected a transformative experience. What I got was a subtle-scented, high-end disappointment that made my overprocessed, thinning blonde hair worse—not better.Here’s what happened:⸻Scent: Clean and SubtleLet’s give credit where it’s due. The fragrance is very mild, almost undetectable—something I appreciate in leave-in products. It won’t compete with your perfume or irritate a sensitive scalp. I thought this was a promising sign.⸻Performance: Left My Hair Feeling Even DrierMy hairdresser first used this oil on me, thinking it might help after color treatment. It didn’t feel hydrating at all. I brought a sample home and gave it several chances, applying it to damp and dry hair alike—but each time, my hair felt rougher, not softer.Instead of sealing moisture, it seemed to highlight the brittleness of my ends. Even small amounts left my hair looking dull, weighed down, and more prone to frizz, not less. It did not detangle, did not smooth, and did not protect.⸻Why It Doesn’t Work (at least not for fragile hair):• No nourishing slip—lacks that emollient softness good oils provide• Too light for dry or porous hair, yet somehow still left a residue• Claims to “repair” or “shield” just didn’t hold up in real use• Doesn’t layer well with other products—caused buildup and texture issues⸻Price vs. Performance: Overhyped and OverpricedThis is a luxury price for lackluster results. I’ve tried many products—from clinical-grade formulas to budget oils—and I rarely return something this quickly. Thankfully, because I’d tried a sample and already knew it didn’t work for me, I was able to return the full-size bottle unopened once my Amazon order arrived.⸻My Hair Type:Fine, thinning, dry, overprocessed blonde—and currently under dermatologist care. I’ve had success rebuilding my hair’s strength and moisture balance with the right mix of products. This was not one of them.⸻Bottom Line:If your hair is damaged, brittle, or color-treated, I don’t recommend this oil. It didn’t deliver on any of its promises and actively made my hair feel worse.Follow me for honest, experience-based reviews. I test both luxury and affordable options for stressed-out hair—so you don’t waste time or money on products that don’t work.⸻Full Ingredients (from official label):Caprylic/Capric Triglyceride, Dimethicone, C13-15 Alkane, Bis-Hydroxy/Methoxy Amodimethicone, Isododecane, Isoamyl Laurate, Fragrance (Parfum), Tocopherol, Schinziophyton Rautanenii Kernel Oil, Squalane, Phytosteryl Macadamiate, Cocos Nucifera (Coconut) Oil, Oryza Sativa (Rice) Bran Oil, Simmondsia Chinensis (Jojoba) Seed Oil, Hydroxypropyl Gluconamide, Hydroxypropylammonium Gluconate, Citric Acid, Benzyl Salicylate, Limonene, Linalool.

Satisfied customer…
My hair was damaged when I had color enhancement. Heard that this was a good product. I have been using it intermittently for about the last three months. And it has helped. Have to use a bit more than recommended on label. I put it in the palm of my hand rub it together.And run my fingers through my damp hair. I will continue using it as long as necessary.

My favorite hair oil
This is an excellent hair oil. I usually add a couple of drops to my hair when it is wet, and 2 more after styling with heat. It’s very lightweight and will not weigh your hair down unless you add too much. It is a bit pricey but if you use as directed it will last a long time. My hair is fine so I need a super lightweight oil. I notice a difference immediately when I run out, so I’m going to keep buying it.

Tengo decoloración en todo mi cabello, y este aceite no mancha mi rubio como otros aceites tipo moroccanoil.

En combinaison avec le k18 crème restructuration sublime les cheveux abîmés ou ternes. Les rends soyeux et brillants.
