AMAZING for humid climates! No more frizz or weird hair
Cannot say enough about how great this stuff is. I live in Florida so it’s a constant battle with humidity and this has been a game changer. It’s lightweight so you don’t feel like your hair is weighed down with hairspray (a common issue I had with trying to use regular hairspray to keep the frizz at bay before I got this stuff). A little goes a long way— it controls frizziness, and my hair still feels soft and I can run my fingers through it. I recommend this to anyone!

Overall great!
This product is great! Make sure to spray a little easy because it will become sticky at times. But once I realize that it works overall great, especially after curling my hair. The hold works pretty good, but as I said earlier, just make sure to keep a decent distance while spraying it and use it lightly and sparingly. Just for reference, my hair type is in between wavy and straight, and I have pretty frizzy hair with a little bit of a wave. My hair is also pretty thick, and this product also does give some shine without looking oil which I love.

Works great – but not foolproof if sweating
This humidity blocker did a pretty good job at blocking out humidity. I honestly think the only reason it didn’t work 100% was b/c we were sitting in the direct sun, in almost 90 degree weather for a wedding & then dancing & my scalp was sweating at times. Had it not been for the sweating, I honestly believe this would have kept my hair completely straight, just the way I styled it b/c I’ve used other products that claim to block humidity & I looked a mess hours into the event. This kept my hair looking good, but it did ‘swell’ a bit – but again, I blame it on sweating.I would definitely buy again for every day use.

Smells Good!
Pretty good hold on my very difficult hair. After 30 years with my stylist (we remain friends), she admitted out loud to me that I have problematic hair – LOL!

OK Product
OK product. It didn’t blow me out o the water. I used it on a hot, humid day. It did not work great but was better than nothing. It does smell good and doesn’t make your hair feel awful or hard.

Really good for hair that reacts to the damp by going frizzy.

Fa quel che promette ma l’effetto è un po quello di una lacca leggera

It works well against humidity. I tried it at home in the summer and it does protect the hair from humidity. However, I went to Punta Cana in July and it couldn’t protect my hair from frizz. In July, it is extremely humid in the Caribbean and the high humidity ruins my hair. It works great for a bit of humid air but not for the Caribbean humid air.
