amazing hair spray

[This review was collected as part of a promotion.] An amazing hair brand. I've been using the conditioning spray for a while now, and I realized it's the best hair product I've ever used. It makes my hair soft, easy to comb after application, adds shine, and also provides excellent protection. I applied it to damp hair before styling. I loved everything about it.

Love this product!

[This review was collected as part of a promotion.] Totally worth it if you style your hair with heat a lot! This product really smooths things out and protects from frying it. My hair feels soft, shiny, and my blowdry didn’t feel so crisp. If your hair’s fine, go easy though!
