body{margin-left:12%}Product ReviewsRated 4.03 out of 5 stars40 ReviewsMost Helpful Positive ReviewI'm Glad I Tried ItMy hair fairly straight, fine, somewhat thin and almost bra strap length. It can be frizzy & anti frizz serums tend to weigh it down or leave it greasy or make it become dirty quickly. Keratin Complex Multi Benefit Treatment Spray doesn't contain silicons that are insoluble, hard to remove and build up. So I tried it. I'm very impressed. It did a great job of controlling frizz while leaving my fine hair very full and smooth. My hair dried quickly & the shine is lovely, not fake looking. Some reviews said the fragrance was horrible. IMO, compared to many other hair care products, this fragrance is quite mild, it isn't too strong for me. I don't consider it pleasant, but I don't find it offensive either. My sinus' are very sensitive to scents & perfumes, & I don't like fragrance to linger in my hair. After my hair was dry there was almost no fragrance left, my hair just smelled clean.Most Helpful Critical Reviewvery strong, cheap fragrancefragrance is a personal thing, it hits the nose differently and it also mixes with your own scent differently but this is without a doubt very heavily perfumed with cheap, chemical fragrance. there's a strong sanitizer smell but also the scent of cheap musk. it reminds the people I separately blind scent tested with of the following things... mosquito repellant, flea spray, Avon skin so soft, Jovan musk cologne. this is choke out your grandma level fragrance. it feels like they haven't updated their fragrances since the 80s. it doesn't fade either. Just a dense fog that slowly suffocates you. I can't tell u if it works, I had to wash it off immediately. it gave me a migraine. I can usually tolerate fragrances pretty well. this smells nothing like any of the popular drug store or salon brands.Reviewed by 40 customersIf you are debating getting this...DO IT5Madie from Glendale, AZThis spray is amazing! I use this everytime I get out of the shower, I use it when styling my hair with heat to protect+smooth it, even when I'm at home and I want to refresh my hair I spray a bit and it makes my hair sooooo smooth. I'm extremely picky about products but this is my favLove it4Sofia A from So CalWent in with dry hair and the rep recommended this product. I use it on my freshly washed, damp hair. I have since noticed my hair is much softer and manageable. I absolutely love this stuff. I don't think it stinks lol and I'll be continuing to buy it in the future. My dry hair is now soft enough to run my fingers thru it. Only con is the price.Good for everyday use.5kasie from Mills, WYIf I use this daily I can notice a difference in how well maintained my hair is. I need this to keep my hair more manageable. My hairdressere recommended this and it is a good product that actually works for me. The quality is there at the same price as other products.Yes I would purchase it again and again4Anita from Middletown NYIt's a great product and works well for the Keritin Treated Hair. The stores needs to have more in stock. Went to the store 5 times for the item.Can't get past the horrible smell.2LML from Northeastern PennsylvaniaThe smell of this stuff is strongly overwhelming, (and not cheap) could be the best hair product in the world but not if it's stinky. Keratin does Not smell like this.This stuff is great!5Mitzi from Waterford, MIUse a ton of this after shampooing before styling and leave in. It's awesome! Strengthens, conditions, protects from hot tools. Love it!Disappointed3Erica from WADissatisfied with the product. Very expensive and it does make ypur hair softer but not the results I was hoping for.Perfume!1Kim from St. Louis, MoVery disappointed in this leave-in. It's heavy on perfume and oils. The scent is strong. I'm on the second day after using it and the smell in my hair is still strong. It's in my hair brushes, combs, pillowcase, etc. Ugh! Not happy! This leave-in didn't seem to do anything other than make my hair smell bad, feel dirty and look frizzy. FYI, my hair is long, fine and straight hair, but gets frizzy in humidity. Perhaps this can work for people with hair that's different than mine, but only for those who can tolerate strong perfume smells.This product has changed my hair!!5Sara from MilwaukeeAlmost finished my first bottle and it has completely changed my hair! I have used it everyday and my hair is way less frizzy! I either leave my hair dry naturally or flat iron it, and the end results are better looking hair! Will keep buying this product.Great for fine hair5Hbaby80 from High Point, NCI have fine hair but a lot of it. This product worked better than my other leave ins! Smells great too without being overwhelming.It's ok3Christie B from MassachusettsI have tried other Keratin products and this one is just ok. It didn't do anything special to my curly hair that I normally straighten.Loooove this smell5Tams from CaliforniaI will continue to buy this product because it works well and smells amazing!!I'm obsessed with Keratin Obsessed5JojoBean from Austin, TXUse this product after every shower since it's so easy to use and gives my hair such dramatic shine. Really cuts down blow-dry time, eliminates frizz and shows off my color!!very strong, cheap fragrance3snikic from usafragrance is a personal thing, it hits the nose differently and it also mixes with your own scent differently but this is without a doubt very heavily perfumed with cheap, chemical fragrance. there's a strong sanitizer smell but also the scent of cheap musk. it reminds the people I separately blind scent tested with of the following things... mosquito repellant, flea spray, Avon skin so soft, Jovan musk cologne. this is choke out your grandma level fragrance. it feels like they haven't updated their fragrances since the 80s. it doesn't fade either.

Makes my hair shiny and removes frizz. Hair looks healthy and is manageable with this product. Love it. Smells great too.I will always keep a bottle of this on hand5Lizzy from Houston TexasThis is the best spray for curly fly away hair I use after shampooing while my hair is still damp I let my hair dry naturally and the results are beautiful soft, no frizz, great smelling shiny hair my husband loves the way it looks It also condition's :)Tangles1Kathy from Dartmouth, MAI spray on wet hair. Does seem to reduce trying time but does not "smooth and moisturize." My hair looks frizzy after drying until i use flat iron. Throughout the day, i get knots in my hair that are hard to get out. This has never happened with any other product.,Love this product!5Pquinn from Coastal CarolinaI live in a very humid climate. Really smooths and protects the hair.I use as heat protectant, not detangler4Traci from ArI got my first bottle of this from my salon. I spray it on before and after using heat on my hair. It's not great for detangling but I will still buy it. The smell alone makes my hair smell like a just left the salon and I LOVE that because people notice. My husband thinks it smells good too. :)I would try other options to compare3Yoli from Spring, TXBesides the effectiveness of the product I consider important the smell on any personal care product *either odorless or a soft fragance). This product in particular fails with this attribute.This is a great product that does what it says it will do!5Chihuahua Mom from Jackson, MississippiThis product works great! I spray it on toweled dried hair right before blow driving. My hair feels much softer and is less frizzy after using. I will purchase this again.Not what I expected2bonsie from V8salia ,CA.It seems as though the bottle was 3/4 full. It feels very sticky even after my hair is dry and it feels weighed down. I will not purchase again.Smells nice but that's the only benefit2Missy13 from CAI usually use Redken One United which i like very much, but I was curious about the 'Keratin' in this product so I bought one to try. With the One United my hair detangles really well and the benefits if using it are obvious, it makes my hair shiny and bouncy. This stuff smells really nice but it does... um, nothing. Zip. Nada. For the price it's pretty ludicrous, thankfully I got it on sale half off. I will be using my bottle up as a hair refresher because I love the scent, but I won't be repurchasing.Must buy4Dovie from OhThis makes my hair feel silky and smells great!!I love this product! ..especially when I travel.5Sandy from INIt is lightweight and adds shine and better manageability. I cannot travel without it!
