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

Less is more AND use conditioner!

For those who found this dried out their hair, please know this is bond repair, NOT a replacement for conditioner. If you have bleached, breaking, weak hair strands, this is only ONE STEP in a healing hair routine – it’s not a one-and-done product. (Please refer to Abbey Yung’s YouTube videos.) On that note, THIS has helped SAVE my hair. My waves had become flat and stringy due to using all the wrong products and being too rough on my strands. In Jan 2025, I switched up my products, started using K18, and was more gentle with my hair. Now I have bouncy, healthy waves that just keep getting better!

So far so good

Only used twice, but noticeable difference with my hair - softer and less frizzy. Hoping it continues!

Not for moisture!

This is a strong protein treatment guys. Worked magic for my chemically straightened hair. My breakage stopped and my hair feels thicker. Hair must have a protein/moisture balance so i do a moisturizing deep conditioner after.

Must have!

I can notice a complete difference using this 2x a week after washes for the past month. My hair feels and looks healthier and softer!

 my favorite one 

I have bleach hair and I’m using a couple times is my third bottle but I love it I will keep buying and keep using on my hair because my hair with this product now is softer. My ends are not split anymore

I’ve been using this product since I first bleached my hair, and it’s been amazing. It helps prevent my hair from turning into a ratty mess and keeps it manageable and healthy. My hair doesn’t feel dry or straw-like anymore. It is a bit pricey, but absolutely worth it — I’d rather spend on one product that truly works than waste money on several that don’t deliver the same results.

LIFESAVER!! My curl pattern was gone due to heat damage! I really thought I had to cut my hair off but decided to try K 18 before I did. I highly recommend trying this before cutting your hair. This is just after one use imagine after 4 to 6. this product is worth the money and I am a satisfied customer 🤎

HOLY GRAIL

Omg if I could give this product 10 stars!!! I recently got a balayage, I’m a natural brunette & of course with any bleaching there will be some damage to your hair. I purchased this to help keep my hair as healthy as I could. Safe to say, my hair has been looking so good! My hair is soft, looks hydrated, and I’ve definitely kept it healthy as much as possible.

Amazing !

Honestly obsessed with this. My hair feels noticeably softer and smoother after using it, without any heavy or greasy feeling. Perfect if your ends are dry or damaged and you want that fresh healthy just had a trim vibe.Smells is gorgeous!

Waste of Money

This mini size should be advertised as a sample… I barely got ONE full pump of product out of this. Complete scam.

3rd time purchasing

3rd re purchase. Amazing product. Hair is healthier and longer due to less breakage and sleekness 👌🏼

An absolute must have for silky hair

So good, I recently bleached my whole head and my hair is the healthiest it's ever been because of this product. I could not recommend it more. I would pay millions for this product.
