Finally have something to protect my bleached hair
[This review was collected as part of a promotion.] I have bleached hair and always choose my products carefully. I was so excited when K18 launched something new — and HeatBounce didn’t disappoint. It’s lightweight, doesn’t weigh hair down, and leaves it soft, smooth, and shiny. Sulfate-free and protects even at 450°F — this is perfect , even if you’re styling hair every day. Finally, I have a heat protectant I can actually trust on my bleached hair.

[This review was collected as part of a promotion.] Very lightweight heat protectant but works well to give a shiny smooth blow dry. My hair feels very soft, and not greasy at all. It is the best heat protectant I have ever used with additional conditioning benefits. This product was Gifted by k18biomimetichairscience for my honest review.
