I recommend

I recommend this product if your hair feels hard or stiff. I apply after shower to damp hair. I love it.

Good Product

It’s a great product, my hair feels smoother but it’s not really effective on my frizz.

Packaging is not great.

Product came in malfunctioning. Pump and dispenser was not working. Had to dissect packaging for the product and product was half dried up and crusty already. Would not purchase again.

Good product, bad packaging

This product made my hair very smooth and shiny and it prevented frizz very well. Only note is that is leaked from the cap in multiple places.

Good one and done product for quick blow outs!

Been amazingly smoothing when I blow dry my hair. Far less fly aways for the entire duration between wash days. Would recommend if you want a simple hair routine on wash days that keeps hair behaving for days.

Good one

Great heat protector, doesn’t weigh hair down. Tames frizz *some*. Texture is a bit slimy.

Weird smell

This product does seem to help with frizz, but I can’t get past the smell. Somebody else mentioned this too, but the fishy smell (maybe a one-off?) makes this virtually unusable. I hadn’t purchased from this brand in years, super disappointed.
