HeatBounce Conditioning Heat Protectant - Hitzeschutz-Conditioner

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.

I really liked this product very light weight I love k18 and all their products

Soft

Make sure you read the how to use.. I pretty sure this is meant to use only before using a hot tool so either before blow drying or curling/straightening. I used it to air dry the first time and weird and made my hair tangle. Then I used it to blow dry and it was so smooth and shinny!

This product unfortunately did not work for me. I have very thick hair & this made it so so greasy. I’m a huge K18 fan & this sadly is a pass.

Won’t be without it

I’m shocked I love this product so much! I have bleached fine hair but LOTS of it! I lack body even with my air wrap, this stuff has given me a great hair day ever since using it! I’ve never ordered a sample so fast!

BUY IT NOW.

Incredible. This is the first product that has added an actual brilliant shine to my hair! I have highlighted blonde hair and this has been incredible! So easy to blow dry with it, after a couple of passes my hair is flawless, damage free and shining like a beacon!

Makes bleached hair soft and silky

This transformed my recently bleached straw like hair into silky and not frizzy! I combined with olaplex hair oil after heat tools. Don’t be shy with the product, I added a little more than recommended and
