K18 Leave-in molecular repair hair mask Review – sarah fynn Leave a comment

hey hey! I hope all is nicely. in the present day I’m sharing my ideas on the very talked-about K18 depart in masks

Since its launch in 2021, the K18 depart in masks has been EVERYWHERE. All people and their mama and greatest buddy within the hair neighborhood has tried K18 by now so when it lastly appeared in one of many creation calendars I used to be so excited.

K18 is a peptide depart in masks that guarantees to work in simply 4 minutes on all hair varieties and textures reversing harm from warmth, chemical companies and bleaching/coloring. You might be directed to make use of it 4-6 occasions consecutively for progressive outcomes then change to upkeep use

Expertise

I used K18 as directed for the first time again in 2025 and I HATED it! I hated it a lot that I didn’t use it once more till March 2026- LMAO. It left my hair so dry and CRUSTY and it felt bizarre not rinsing it out or not utilizing a conditioner. I believe I’ve PTSD lol as a result of how can nonetheless bear in mind this virtually 2 years later LOL

Anyhow this 12 months I used to be actually decided to complete and provides it one other probability so I did a bit extra analysis on 4c hair use and lots of people use as directed however comply with up with a masks for hydration so I believed to attempt that. So in March I used it 4 occasions consecutively, depart it in for 4 minutes earlier than following with a masks, I used the Amika hydrorush masks left on for added 20 minutes earlier than washing it out. I took a break in April because it was then time for my traditional Olapex treatments- I didn’t need to use them collectively in the identical wash day. I additionally then had a wig on for vacation. I used the final bit final week.

Utilization is fairly simple: after washing and towel drying my hair, I cut up my hair into 4 sections, use a pump and a bit per part and canopy with a bathe cap. The feel is light-weight and seems like a lotion so it spreads nicely. it’s not slippery so I didnt even attempt to detangle with it

Outcomes

In whole K18 lasted about 5 wash days. 1st time in 2025, in March 26- 4 weekly washes then ultimate use final week however there was solely slightly left and it did half my head

Truthfully I don’t know if it did something to my hair. I used to be positive to pair it with masks I used to be already accustomed to so I may inform if there was any extra advantages. My hair didn’t really feel any completely different in March after utilizing it weekly. I had my routine trim in April and I used to be informed I’ve a couple of travelling cut up ends and a few harm and I instantly thought however I’ve been utilizing k18? I don’t assume they explicitly say it repairs cut up ends however I really feel my harm may be from warmth? again in feb I bought the wavy discuss thermal brush and I could have abused it on my fantastic hair lol so if k18 repairs warmth harm then shouldn’t my hair app have gone in a different way?

Verdict

I don’t know. I don’t really feel like my hair is any completely different after k18 use. I’ve now completed the bottle, I had the 50ml dimension. I may need been heavy handed because it lasted 5 washes. I wont purchase this once more, I believe for now I’ll follow Olapex as my commonplace bonding remedy.
