Damaged hair.
K18 Leave-In Molecular Repair Mask 15ml
Rating it 4 because I’ve only used it once so far. My bleached hair didn’t feel dry afterwards so that’s a good start :) I’ll update once I’ve used it a few times

This is probably the best product I’ve used for bond repair.
My ends are fried from a chemical straightening process, and three uses of this has made by hair feel sooo much softer and healthier.
Will definitely repurchase
Can never go wrong with K18! Love it
This stuff is AMAZING!!!!
Fast delivery and good offer
Pretty average with a hefty price tag. I have fine, platinum hair and didn’t see or feel any noticeable difference after 4/5 uses of it. I also really dislike that this has to go on shampooed only hair - quite hard to work it through shampooed only blonde hair without shedding and tugging hair out as you’re trying to work it through. Wouldn’t recommend, especially at this price point for such a small amount.
Amazing product! Expensive but definitely worth it if you have bleached hair!
Works miracles

Wow! This works amazing, transformed my brittle hair, got the bigger bottle to make sure i have some in stock
Love this product. Keeps my blonde hair strong and vibrant
This product works its magic on my fine damaged hair , the result being my hair is now shining like a a much younger persons hair, I have just turned eighty and live on just the age pension but still take pride in my hair and save for my next bottle. Thank you Synergy for creating this wonderful product I now have confidence in my appearance.
Only used once but kept my hair feeling soft I’ll use it every few weeks
Love this. Instantly smoothed my hair.
Expensive but worth it.

Once a week and it keeps my wavy bleached hair looking amazing.
Slay, always a slay. K18 leaves my hair feeling amazing. Wish it was cheaper though!
Very good!
Delivered efficiently amazing item
love it!! i’ve used it twice now & it works wonders, my hair already feels so much better
This product is magic in a bottle - it takes a bit to get used to (leaving for four mins then going about the rest of your routine) but the results are AMAAAAAZING! My ends are healthier, my hair feels stronger and less brittle and overall just looks healthier. I cannot recommend enough!
Awesome product! Leaves my hair feeling so soft
Hair always feels so much softer after using
Used this very expensive treatment three times according to instructions my hair is lovely for two days then back to the dry look my hair dresser used the wrong perm and destroyed my hair I live on an age pension and to find $55 for this that has not really helped is not fair
