K18 re-formulated this conditioner and it’s not the same. Much thinner and therefore less hydrating :/ the packaging has been downgraded too. Feels like a cheaper product all around. Will be trying something new next time!
I don't get the hype or claims for this product. Smell is good, but slip isn't there as they claim. It's not instntly detangling, it requires CAREFUL combing after use, and definitely did not provde passable heat-proof hydration. This will be a return for me
Was disappointed in this one /: the formula is really thin and my hair is sooo hard to brush after use. Feels like I didn’t use any conditioner at all. Smells nice though!
It’s good and seems to keeps my hair very soft. It says not to use with the pump conditioner but I still do. Smell is ok but not great.
I like this a lot and have repurchased a few times, I just wish it was a little thicker / the formula feels thinned out. You definitely *have* to comb this through your hair in the shower for it to be effective. I use it with the olaplex fine hair shampoo and K18 heat bounce. My hair feels soft and the combo seems to have halted damage, but as the day progresses the damaged parts of my hair (last few inches) still start getting tangly. I think this product yields better results than the K18 leave-in conditioning mask.
Great shampoo and conditioner combo. If you need a deep condition for you hair this is more lightweight. Very expensive
Did wonders for my frizz prone, fine hair. Worth its weight in gold (even at today’s gold prices)!
I love this conditioner and i noticed how healthy and thick my hair has become since using it. i highly recommend!
Used to love this conditioner before they changed the formula without notice. It used to be a really thick consistency and felt like it was actually doing the job it claims. Now it’s a much thinner and more liquid consistency and I notice it’s not moisturizing or protecting my hair. Really bummed that K18 changed the formula. Two bottles have been the same more liquid consistency and I’m weary to buy another for fear it’s going to be the same issue.
Very lightweight but deeply hydrating. Smells neutral. Detangles hair very easily & rinses easily. Plus I love that it’s silicone free, so you don’t have to worry about buildup. I also noticed my hair was more manageable after using the damage shield line from k18.
