HeatBounce Conditioning Heat Protectant - Hitzeschutz-Conditioner

Only hydrating, not full moisture

I've tried using different spray amounts and also just applying it to my hands first and running through the hair - I find this method works best, considering this is a milky product. If you colour/process your hair, this won't be enough moisture. I dye my hair blonde and this product worked decent through the summer heatwaves but once temps got cooler, I had to reach for the leave-in mask version. Not crazy about it and I don't think its worth re-buying as I can always use less amounts of the k18 mask and just have 1 go-to product all year round. In the end, this is case dependent how thirsty your hair is..

Definitely worth the $

I have only used this a few times but even after first use I noticed a noticeable difference with way less frizziness. (I have fine, thin and frizzy hair. Good times.). So I’m sure it’s good for heat protection but this was added bonus.

Game changer for my hair routine!

I absolutely love this product! Yes the scent is strong, but I enjoy it and it doesn’t linger in my hair for long. I use it on damp hair before blowdrying and it makes my hair so soft and not frizzy at all. It is not greasy at all and I have thin hair.

Not it

I really wanted to like this because of how many good things I hear about for k18 products but it just made my hair feel greasy and dull? I have used it twice, both with different amounts just to see and both times it feels like my hair has a grease layer. I have thin type 3 curls and my blowouts are so stiff after using this :(

New must have!

Amazing. Blew my hair out as usual and folks were like, your hair looks great, what did you do differently?

Itchy

I like the product but…I have to make sure I don’t get it on my scalp or it makes my scalp itchy. It works pretty good for the hair. Mine is fine but thick. It makes my hair silky smooth and moisturized just right. But the scalp is a no. I wont repurchase but I’ll use what I have.

I was recently gifted this product in exchange for an honest opinion. I really wanted to love this product because most of my k18 have been great. However, you have to be very mindful when using this product. Separate your hair in small sections and only use a bit at time. If use too much, it could leave your hair greasy. The smell is a bit strong too.

A miss for me

I wanted to love this because I swear by k-18 products. This was endorsed by my favorite influencers and Elle’s 2025 Top Products. Despite the endorsements, this left my fine hair limp, lifeless and heavy. Adjusting the amount used did not help.

Greasy hair

I have long, fine, afro-curly hair and this made my hair kind of greasy before I straightened, which is a bummer because it’s a lot of work to straighten my hair, so prep products really matter. I doubt I’d use this again for a silk press

Can’t use it because of how sick the fragrance makes me. Instantly gives me a horrible headache, has me nauseated, and my eyes are burning. Definitely avoid if you ever get migraines or have sensitive skin or eyes

too stunned to speak

never ever write reviews. after using with my dyson i cannot stop running my hands through my hair. I work at a hair salon and have tried EVERYTHING this is holy grail. I see so many one stars because of user error. use on wet hair guys!!! and it needs heat!

Does wonders on heavily processed hair

I bleach my hair every 4 weeks and tone it as well. I have tried the most high end hair care but nothing makes my hair feel as smooth and silky as K18. The spray is a very thin mist so I rather spray the product in my hand and work the product into my hair. I can highly recommend buying this. It breathes new life into hair that feels and looks like a dead grass.
