GoldwellStyleSign Smoothing Serum SprayClimatePartner certified

I love this stuff! Smell is light, easy to use, and works great! It does come in a small bottle, I wish it was a bit bigger. I love that this can be applied to dry hair before styling as most thermal protection products have to go on damp hair. Doesn’t change the texture of your hair either which is another plus for me!

Love this product! Spray on and flat iron comes out so smooth

This thermal heat protectant is a fantastic product! It’s not too heavy or greasy, which makes it perfect for everyday use. It provides excellent protection for my hair against heat styling tools without weighing it down or leaving a sticky residue. My hair feels soft and looks shiny after styling, and I’ve noticed less damage and frizz. Overall, it’s a great addition to my hair care routine, and I highly recommend it for anyone looking to protect their hair from heat damage!

This product protects hair from heat just as it claims. It is not heavy or sticky and leaves hair sleek and without residue.

Love how this makes my hair feel, easier to style and less frizz. Great product, highly recommend

I have tried other smoothing serums and this by far has been the best! My hair has some curl and frizz to it and this product calms it down! Will definately buy again

Every time I use this product with my professional level straightening iron as long as I am not caught in a Floridian mid afternoon downpour my hair which is naturally wavy and frizzes stays straight and sexy

Goldwells Smoothing Serum makes my hair sleek and shiny.. frizz is gone!!
