Leave-in Molecular Repair Hair Mask - Treatment for Damaged Hair

Miracle in a Bottle

I just bought the mini and used it once today. My hair is already looking so much better. I’m so excited to keep using it. Will definitely have to purchase the full size. My hair is bleached. Been getting highlights, dyed, and balayages for years. This product is well worth the investment.

Lives up to the hype

One of those products that, despite being expensive, is worth every penny. I was reluctant at first to wash without using conditioner but K18 makes the hair so silky, you don't even notice you haven't used conditioner.

I think it works

I think it works, but how can you really know? Ive used 3 bottles and my hair seems to grow without breaking as much but that may not be down to this product. Its easy to use though, however its very expensive

It’s okay

I lost half of my hair to bleach damage and got this hoping it would help. I think I noticed a slight difference immediately after using it, but as soon as I washed my hair again, it went back to feeling damaged. This may work for prople with heat damage or who want to majntain the healthy of already healthy hair, but this did not help my very damaged hair.

Not for Protein Sensitive Hair!

Oof...I got this as my birthday reward and gave it away. This made my hair super I My friends and husband even noted that my hair looked dull. It took a couple washes & deep conditionings to get it out. If your hair is protein or keratin sensitive I'd avoid this.

Would recommend

Great product if you bleach your hair! I use it when needed and it honestly last me a while and I have long hair. Makes my hair feel softer the days I use it and definitely helps with breakage over time. Ps

High Recommend

I’ve been using the K18 Leave-In Molecular Repair Hair Mask from Sephora, and I’m seriously impressed. My hair was feeling dry and damaged from coloring and heat styling, but this product brought it back to life. It feels softer, stronger, and much healthier overall. What I love most is that it’s super easy to use — just a few pumps after washing, no rinsing needed. It doesn’t leave my hair greasy or heavy, just smooth and manageable. After a few uses, I could really see and feel the difference. It’s definitely worth the investment if your hair needs repair. Highly recommend!

This product is amazing ! Used it for a few months my hair never felt better and it definitely helps with hair growth. I have seen a huge difference. Highly recommend.

Exemplary!!!

I have dry damaged frizzy hair after a hair colour change and I have been using Olaplex and redken for months which stopped my hair from getting worse but it is no better. Decided to try k18 and from the first use restored my hair to a sleeker smoother healthy head of hair! I admit the price point was off putting but when I think of what I have spent this is worth every penny and I have thrown out everything else. Thank you K18 no more tears!

A must have

if you invest in one hair product, let it be this.

Holy Grail

If you bleach your hair, pleaseeeeee do yourself a favour and splurge for this product. That is all 🫶🏼

Amazing Treatment!

Great for hair that is bleached and regularly exposed to heat.
