Science backed greatness
(This review was collected as part of a promotion.) I was gifted by K18 to test this product. I have used k18 styling oil, before. The ends of my hair never get split-ends anymore and I have received many compliments about the improved texture of my hair. So I was really excited to try this heat therapy product by k18. I used this before using my blow dry brush and my blowout lasted a good 4 days! I have lots of hair that is naturally very textured and I noticed it helped combat frizz and calmed my hair! I would totally recommend this product.

[This review was collected as part of a promotion.] I received this K18 HeatBounce Leave-In Conditioner Heat Protectant complimentary from K18 in exchange for my honest review. This leave-in conditioner works beautifully on my towel-dried or damp hair prior to blow-drying. My hair looks glossy and feels silky after blow-drying or heat styling with my curling or flat irons. I love the way my hair looks and feels when using this leave-in. I also love that it helps protect my hair when using heat styling tools. I would recommend this leave-in Conditioner and protectant.
