Decent product that helps beat humidity
I live in a very humid place and I hate that whenever I style my hair as soon as I walk outside it goes frizzy and looks like it has hardly been styled. This product helps it look styled and presentable still. It’s not a magic cure but it certainly helps.

It ok
It claims to be the same formulaas the old packaging, however it definitely has a different smell to it. It's ok, I don't think it really does help with humidity that much on my blonde thin hair.

Too greasy
My hair is fine and blonde. Although the product does reduce frizz, it's way too oily. My hair looks instantly greasy, even when using a very small amount of the product. It seems much more like a hair oil than a hair spray.

A must for coast dwellers
I can't go without this product. It's great for keeping the frizzies at bay in our humid climate and it has a very pleasant scent, not at all overpowering.
Written By Pam On 06/04/2015
This product is the only one on the market that I have managed to purchase that stops my hair from frizzing in the rain or humidity. Brilliant! Highly recommend it
Written By Joan On 18/09/2013
I bought this product thinking it was hair spray, so naturally when I went to use it to hold a style I noticed it wasn't although I used it anyway and my style still held in place all night and when the rain rolled in later in the night, my hair held up against the moisture in the air and did not frizz as it usually would. Overall I'm very glad I bought this product now.

Humidity Friss Banished!
KMS Humidity Spray brilliant, so glad I found this product before my trip to Thailand - cannot have a frizzy MOB !!

My fav hair care product ever
I used to use this before kms changed packaging and freaked out that they had stopped making it but luckily I looked it up and bought it from myhaircare. My hair is naturally very curly and frizzy and when I straighten it, it often succumbs to the humidity - but when I use this product my hair is glossy and smooth for hours! It also adds a lovely shine (which is good for me but may appear greasy on fine hair).

They say a dog is a man's bestfriend.....
For those of you ladies out there that have thick and freezy hair like mine, you will sooner forget your mobile phone than to leave the house without your KMS ;)

Works for me!
I live in the tropics, so it can get very hot and humid. My hair is wavy and frizzes easily, especially in this climate. This product made my blow dry and straightening a breeze! My hair is soft, shiny and frizz free and it does not look heavy and oily. A+!
Written By Val On 14/05/2012
absolutely fabulous
Recommended by hairdresser have just purchased today and it does EVERYTHING that it says. I have extremely fine, thin, short coloured hair and with any heat or humidity it becomes limp and frizzy. After a small spray of this product it has lasted all day long in high humidity. It is amazing. My style has remained smooth, shiny and no frizz. Have tried many other products - this leaves the others way behind!!!

Best product for humidity yet!
This product is perfect for spraying on your hair after straightening or blowdrying. Because it's a light mist, it doesn't help with flyaways quite as much as a serum would but it definitely stops your damaged locks expanding to four times their natural size in humid weather. Not at all greasy as long as you don't go over the top with application. I use post-blowdrying in combination with Evo Icon Welder Hot Tool Shaper and this combo doesn't make my hair greasy at all - just party-ready!

KMS: Flat Out Anti-Humidity Seal
It does stop frizz. But what put me off was that it makes hair look very shiney, kind of oily. I personally like my hair to look pretty matt so I wouldn't purchase this again.

KMS flat out
This is the best dehumidifier spray I have found - it keeps your hair soft and shiny all day, stops the frizzies caused by straightening and my hair stays straight even in the rain.

Smooth but no hold
Gave a nice smooth finish to my hair without being sticky. Great for humidity but not as a holding hair spray.

Rainy days a thing of the past
A must have item, I can't imagine not having it to finish off styling and taming the 'static' short lengths. Rainy days are a thing of the past
Written By anonymous On 10/02/2011
Frizz free, shiny and nice smelling hair!
This is a must for me. When my hair is totally dry I apply this to keep it frizz free. It adds a little shine and it smells great. It works too to add a little 'life' to your dull style after a busy day.
Written By anonymous On 06/01/2011
Excellent product - even in high humidity.
I have been using this product for 12 months on my frizzy hair even in high humidity. I have keratin on my hair, but there is absolutely NO sign of frizz. I am on my 2nd container.
Written By Jennie On 30/12/2010
Great product!
I love KMS Flat Out Anti-Humidity Seal. I use it after straightening to give a little extra protection for frizz, to stop flyaways etc. I also use a little sometimes instead of hairspray when I only need a little bit of help holding hair. I definitely would recommend this product.
