I have long straight hair but tend to get frizzy around my hairline.Reviewed by 109 customersOne of my fave products!5ReggieM from Rome, GAThis is one of my favorite products ever!! I use this on my wet hair before drying, then again before I flat iron. It makes my hair so smooth and shiny! It's truly like a keratin treatment in a bottle! I also use this on my ponytail to make it extra sleek as well as my roots when I have my hair pulled up to help give me the slicked back look. Truly a dream product! I've had many compliments on how smooth my hair is!Horrendous1Francine from New YorkAbsolutely awful. Did not make my hair soft at all and I cant get past the smell. It smells like chemicals and makes me cough. I swear it reminds me of Raid wasp bee spray. I had to leave the room after I sprayed it because I couldn't breathe. I have tossed after trying to use it twice. I am not sensitive to smells but this one I just could not handle.I'm on my 10th can!5Feggie from FloridaI have highlighted and colored hair that has some damage. This product makes my hair shiny and smooth. I use it before I put my Velcro rollers in, after blow drying. It makes my hair incredibly smooth. Please never stop making this miracle product!!Highly recommend for all hair needs!5Jennifer from Scottsdale, AZSmells like marshmallow heaven!! I will definitely getting the bigger size. I use it everyday because it refreshes my hair and gives it back some shine, bounce and volume between washes!!Pass. Better products.3BeautyFriend from CaliforniaA good product does what it says AND doesnt mske yoir hair appear as if you washed it a dew days ago. Not a good look. Better products available.Terrible!1Phyllis from San DiegoMade my hair feel like straw. Thankfully I bought the trial size but still expensive and a waste of money.Definitely works5 from Newport News VirginiaMy hair is frizzy curly definitely takes care of that works wellMade my hair greasy and limp2BrewersGirl from Milwaukee, WIThis is a great concept but it made my fine hair (I have a lot of it) limp and greasy. It also felt like it left a film on my hair. On a positive note, it was great with heat protection. I feel like sunce this has protein in it, it should only be used maybe 1-2 times per week at most, as my hair started breaking off.I would buy again5Vanessa from San Diego, CAI tired it out because my hair stylist used it on me and I ended up liking it! I love that y'all sell the travel size, I tried it out and loved it. Going for a bigger size next time I'm in.Very nice spray that actually works5 from PennsylvaniaI have short straight hair that never looks finished …I use it the day I wash my hair and I use it on the unruly days it is such a nice product my hair has a much nicer look.My "Go To" TravelSpray5Jean from Millsboro DelawareMy favorite spray. Light hold and it protects against humidity. No fragrance!Absolutely love this.will absolutely buy this again5Pija from TexasThis is a good product. I fee that my hair does not look dry and brittle after using this product. I want to try the other products they make.Amazing5Kaite from Myerstown, PaBought travel size just to see if it would work and it is amazing it's not greasy and your hair doesn't even feel like you were using heat on your hairMeh2AC from ChicagoThe smell is very strong. Hair ends up a bit stiff and dry. There are far better products out there for less $.My Favorite in Travel Size5Jan from Charleston, SCYea!! Great to have my favorite smoothing spray in a travel size. Good Behavior is the best for keeping my hair smooth and as frizz-free as possible on rainy, humid days. Since I travel a lot, this was a great find!Great Product!5Beth from Columbus, OHThis product makes my hair look like I just walked out of the salon with a keratin treatment. I was so impressed by the product that I told my hair stylist who tried it and now recommends it to her other clients.I probably wouldn't buy it again.3Terri from Lubbock, TxMy hair doesn't look silky like they shop on the videos. I do like how it makes my hair smell.Great stuff!5Karma G. from undisclosedit doesn't matter whether it's travel size or regular size. This stuff is the best. I am just so happy now because it is small enough to take on the airplane.This is the Worst product & Damaged my hair1Laurenb from VirginiaI wanted to love this because a lot of hair stylists and people recommend it on TikTok but this does nothing to help you're hair, it dried out my hair making crunchy, knotted up & hard brush through I've never had my hair in this horrible condition before and I noticed my hair frizzed up, and I started losing hair which before trying this product my hair was fine, I don't use heat on my hair, I don't use any hair styling tools, I was just looking for a leave in spray and this was recommended to me but it's not a good product please, I should of read the other reviews before I purchased this from now on before I buy anything I will have to read the reviews first normally I do but what what I'm seeing I'm not the only one who had the same similar things happen to my hair because of these products, but it made my hair feel like I had a bad bleached job done on my hair my hair was dried out & rough feel, also also stringy feels and my hair was fine before I used this product, this product needs to be recalled & taken off the shelves because obviously I'm not the only one having issues with this product, This is to much of a pricey product just for it to damage you're hairWorks Short Term but leaves hair greasy4LEA7 from undisclosedI liked what Good Behavior did to smooth frizzy hair, but it also made it necessary to wash the next day, even when using the dry shampoo. So - great for same day look, but plan on washing the next day.Not satisfied1Ivonne M. from undisclosedLeft my hair sticky, no soft or smooth. Won't used it againThis did everything it said it would5Christy from Midland TexasMy hair looks amazing no frizzFantastic5Pam F. from undisclosedProduct did exactly what it was meant to do.
