body{margin-left:12%}Product ReviewsRated 4.22 out of 5 stars54 ReviewsMost Helpful Positive Revieweffective protein treatmentI have thin, porous loose curls. As a result, my hair loves protein. My hair is not damaged or color treated. I merely used this product for the protein boost. First I shampooed, then I squeezed the excess moisture from my hair and applied the reconstructer. I let it sit on my hair for roughly 5 minutes while I finished showering. Finally, I rinsed and applied my normal conditioner, detangled, then rinsed. When I styled my hair I could see that my curls were holding their shape better than normal. I even air dried 80% before diffusing for 10 minutes. I typically don't air dry because the water weight is too much for my fine hair and my curls get stretched out; however, the k-pak reconstructer gave my curls needed strength to hold their shape even while damp. I could definitely see myself using this once a week. I agree with others that you must balance moisture with this protein treatment. I used a rinse out conditioner and a small amount of curl cream to help balance the protein. having said that my hair needs A LOT more protein than moisture, so keep your own personal hair needs in mind.Most Helpful Critical ReviewNot moisturizingEarlier this year when I had really dry hair I went in to Ulta and asked for a mask that would be moisturizing for dry hair. The rep brought me to single use and suggested the Joico k-pak. I loved it. When I went back last week it appeared they were recently sold out. When I asked I was told they were discontinued but they had the full size. There were several Joico mask options this time around to chose from and with the help of the Ulta rep picked this one. Either it was not the same one or they changed the formula but it was so bad I had to add my regular Pureology conditioner just to be able to get my fingers through my hair. It did not moisturize at all. It actually made it drier, plus it was pricey. I am super disappointed. .Reviewed by 54 customersHair so soft54evayoung from TexasI am 60! I like highlights in my hair that leaves my hair dry and brittle. This product left my hair so soft after one treatment!Wow5April from Flint MII have thin blonde hair and this turns my hair into silk. I am a product junkie and have tried MANY different brands! I am in love with almost everything in the Joico line but this is probably my favorite.Restored my over bleached hair5Melissa from Las Vegas, NVThe first time I used this was back in 2011. My hair was so damaged from bleaching. We're talking close to rubber. This saved my hair. I was told you can use as many times daily on non wash days. So if you wash once a week you can use every day excluding wash day.Does what it says5Toya from New YorkThis works! I was in need of protein after a color service. It immediately gave my hair the boost it needed so my fine type 4 hair was no longer limp. I've used it with and without heat and it worked great. I always follow up with a conditioner.Best product for damaged hair5Sunney from Provo, UtahI've used this product for 5 years. It works magic in my color-damaged hair.A Must Have!5Brandi from Columbus GaI love this treatment... I used as directed and a little longer when I can. I only use it twice a month or days when I feel my hair really needs some extra love, so it last me a good while.It has replaced my olaplex 3 ...I've tried several products for repairing my damaged hair this def stands out. You can feel a difference in one use and I have a good amount of hair but it's very fine and it does not weigh it down! Will always have a bottle of it! Literally waiting for Ulta to do one of their sales I think I paid around 20 something the last time I bought it and it smells delicious!great deep conditioner5Tracy from Seattlelove this reconstructor. smells great, makes my hair feel soft & managable 1 item to never run out of.Great Mask!5Ren from SLCI have bleached hair and this has been awesome for restoring lost moisture. My hair feels bouncey and hydrated after a few applications. This is budget friendly, I will repurchase.Already bought again!5Amma3 from North DakotaHad help choosing this product at my Ulta store. I was skeptical because I have used other Joico products and wasn't a fan. When I applied this to my hair the first time, I was like nope it's going back. But this made my natural grey hair soft and silky. Will continue using this product and may even try the shampoo and conditioner again!!Surprisingly effective!5Becky from Round Rock TexasI accidentally purchased this product thinking it was the hydrate version. My hair has been highlighted and colored over the last 4 months and the ends are progressively getting dry and almost brittle. This product was more effective than the one I was intending to purchase. My hair feels stronger , hydrated and looks shiny and healthier. On the first use it seemed to almost seal and repair those dry ends. I really saw a huge improvement after a second use. I feel like I walked out of salon with a professional working on my hair. The results are dramatic. I will say that I didn't quite like the smell. It has a hint of banana? coconut? smell. However I am not hung up on that because this is an amazing product and far exceeds expectations.I would buy this product again. It works great!! My hair fee5Rho from Philadelphia paIt works miracles. My hair looks and feels amazing!!yes, i love it and the way it makes my hair feel5non from morton msi started using this week, using daily then next week everyother day, it is great, makes my hair so soft and manageable.My hair was so fried5Hairgrl from Athens, GAI recently got my hair lighter, idk if my stylist is using harsh products and my hair is dry to begin with, but everytime my hair is fried. I've used K-Pak before, and it works miracles.Good but…4Kate from BaltimoreI love this product. I love the way it smells and the strength it gives my 4c hair. I will say, something is different about my hair. I'm not sure if it's the keratin but my hair is way looser in curl pattern than usual. Almost like I slightly chemically processed my hair. Not sure if this is a typical result but otherwise it's great.Not What I expected1Marymill from Chicago, ILI have very fine, long, & recently over processed hair. Which of course, left it damaged. I left this on for almost a half hour. Used it 2 x a week. For one week. After that I tossed it out. It made absolutely zero difference, even after rinsing it out. I couldn't get comb through my hair. Left it dull & weirdly thinner than it normally is.Great hair mask.5Lluviaradz from Northwest IndianaGreat product, leaves my hair smooth and manageable. I only use it once a month and that's enough for my hair. I alternate with a more moisturizing deep conditioner for perfect balance.10/10 protein treatment!5bsooner from OKCThis is NOT a moisturizing product. This is a protein treatment. It will not make your hair soft. That said, it is an amazing protein treatment! It really helps make your hair stronger. I only use once every other week on fine, thin hair for ten minutes (unlike the five it says) It does smell like bananas, I don't mind it though.Love this stuff!5DaisyMay from Auberry, CAI color and highlight my hair. I also have very hard water where I live. As a result, my hair is dry and damaged. I use this Joico reconstructor once or twice a week, and then use Kpak conditioner right after since it doesn't really detangle my fine hair. At first, it doesn't feel like it did anything, but once my hair is dry, it is soft and feels like normal healthy hair, instead of straw.Smells terrible and wasn't any better than cheap conditioner1VNez from Cleveland ohioThe smell was bad. Like nasty oatmeal. It was lumpy. And it wasn't probably even as good as cheap $1 conditioner. I'm taking this back. I have used the Cake brand and it's a million times better.Amazing5TMC from TennesseeMy hair was damaged from using this brands volumizing shampoo! This K-Pak has revived my hair and works amazing. I would def recommend this to anyone with damaged or distressed hair!This product smells so unplesant!1Lisa from Shalimar, FLI dislike the scent of this!!!! I'm returning it ASAP.Holy grail5Em from OregonThe negative comments are about this drying out your hair this is not a moisture mask!!! Use conditioner or a moisturizing hair mask after. This is to add protein to hair. It truly fixes damage quickly!!! I bleach my hair and over processed my bangs where they get stretchy when wet/break off easily, this has immediately remedied the ends and made my hair feel so much more healthy! This is a product you should use once or twice monthly at most as too much protein is bad for your hair- if your looking for moisture this brand has the most AMAZING moisture mask. It's in a purple bottle.SO Good.5J from AZMy fine, wavy/curly hair was limp and lifeless before this magic was introduced to me a few weeks ago. I will never go without it again! I clarify and then used once weekly at first, followed with the Intense Hydrator. Will reduce to once per month once my hair's health is fully restored.effective protein treatment5dannie528 from CTI have thin, porous loose curls. As a result, my hair loves protein.

It is one of the best protein treatments available, must be used only once or twice a month, and followed with a "super" moisturizer like a previous customer stated in her review. I use Joico's Moisture Recovery (and the two products used only once a month) have done wonders for my mildly relaxed medium-long hair. From what I've learned over the years from the pros, hair needs a balance between protein and moisture.
