Molecular Repair Hair Oil, Weightless Oil for Stronger, Healthier Hair, Suitable For All Hair Types

I’ve been using this hair oil for a while, and it really works for my hair. It helps my hair feel smoother, softer, and more manageable without making it feel heavy or greasy. A small amount goes a long way, and I’ve noticed my hair looks healthier and more polished after using it. I’m very happy with the results and would definitely recommend it. ⭐⭐⭐⭐⭐

Great hair oil. Made hair softer but not weighed down. A little goes a long way.

This is a tiny bottle but I really like this stuff and you only need a tiny bit.

I purchased this due to an online referral. Just used yesterday. I have fine, dry, aging hair and was very pleased with the results. Always concerned about an oil weighing it down, but this one worked beautifully.

This did absolutely nothing for my hair. Have tried to use it several times (sometimes less product, sometimes more) and it made no difference. Definitely did not help the frizzies. Did not make my hair one iota shinier. I was really disappointed in this because I did research and read reviews to decide to buy this product. Maybe there just isn't a product out there that makes my hair shiny and smooth (other than using AI to touch up your photos LOL).

Very small bottle but the product, to me, was amazing. Leaves my hair so soft and the smell is nice. Only problem is now I want all their products, but the price is very high, especially for the amount you receive which is why I only gave it 4 stars.

I love this K18 products, very reconstructive, a little expensive but is a great product for over processed hair, you see the results in a few days, I highly recommend it for blondes 🫶

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 Subtle Let’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 Drier My 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 Overpriced This 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.

Lo consiglio mi hanno fatto 3 decolorazioni mi avevano rovinato i capelli con questo prodotto lavando i capelli 3 volte a settimana facendo due lavaggi i capelli si sono ripresi alla grande

This is how big it is… I guess I bought a travel size for rps.2,700. Haven’t used it yet but the price is very high for what 10ml, my mistake not checking before buying, hope it works
