Description

Meet the award-winning hair treatment that’s captured the hearts of millions of stylists -- a beloved “hair hero” that delivers instant transformation to stressed-out, damaged strands. Fusing powerful amino acids with Joico’s smart Keratin hair treatment technology, our 5-minute Reconstructor rebuilds, refortifies, and improves elasticity for hair that’s been ravaged by heat styling, chemical services, and the environment. Directions: Apply to damp hair. Leave in at least 5 minutes. Rinse. Rebuilds and re-fortifies damaged hair. Whether the culprit is over-zealous heat styling, chemical processing, or harsh environmental factors, even brittle and lifeless locks make a glorious shine. *When used with K-PAK RevitaLuxe K-PAK Reconstructor Color Therapy Luster Lock K-PAK Hydrator CT Luster Lock Spray Will the products help protect against flat-iron damage? Absolutely! Whether the culprit is over-zealous heat styling, chemical processing, or even harsh environmental factors, K-PAK safeguards against damage, dryness, and dullness. Will the Clarifying Shampoo strip my hair color? Nope! Our color-safe formula delves deep to remove product residue, excess oil, and impurities that can dull your hair’s luster and weigh it down—without stripping away shine and slip, or diminishing your shade’s vibrancy. Do you have a deep-conditioning treatment that won’t weigh down my fine hair? Many intensive treatments come on strong, but our Liquid Reconstructor deeply nourishes hair with a super-light, spray-on formula that won’t weigh fine, fragile strands down. My hair is fried from too heavy highlighting. Which product is right for me? K-PAK Hydrator is a thirst-quenching treatment that delivers intense and immediate hydration to parched, overprocessed strands—making it ideal for your dry, damaged hair.

Style: 8.5 Fl Oz, New Look
Smells amazingly good and makes my hair feel wonderful. Very pricy but quality stuff. I found that if I just put a small dab and water to mix then put on my wet hair, it works beautifully

    • Bye bye breakage! Joico Reconstruction kit really works!
Style: 8.5 Fl Oz, New Look
I bought the whole Joico reconstruct kit on amazon and I'm so happy I did! Fact is that my hair was bleached in a salon, but it somehow destroyed my hair. Every time I had to wash my hair, it was a nightmare! I tried Therapiste from Kerastase first for no big difference, then I tried Penettraitt from Sebastian and saw some improvement on the hydration side, not so much on the reconstruction side. Additionally, I tried BC Bonacure pepitide repair nourishing and was able to see good improvement but still some breakage. Finally, Joico got me tremendous improvement on hydration and reconstruction in just one application!!! Im AMAZED!!! The secret, in my case, was to apply the joico kpak cuticle sealer and the deep penetraiting reconstructor masque twice. I also used the Joico kpak clarifying shampoo as the first step plus the Joico kpak intense hydrating masque as the last. Finished with Pureology color fanatics leave in spray and Kerastase blond absolu oil. THE RESULTS: My hair had almost no breakage while blowdrying, it was extremely shiny and super soft. I wish I knew that Joico treatment 3 months ago! ... show more

Love this stuff. Pricey, but so worth it! I don't even spend this much on face moisturizer, lol. A long time ago, a hairdresser needed to strip my hair twice, and I was told that my hair would never be the way it was. Well, I wanted to prove that person wrong. I've done my best to take great care of my hair through the years. I rarely blow-dry it and don't wash it every day. I use this product whenever I wash my hair. I know it'd be good to use something else sometimes and use this once a week or so, but I love it. I feel that it works well. It helps tremendously with tangles and it smells great, too. I don't curl my hair often, but when I do, I use very little of this product (or none) because I want the curl to last as long as possible. Because the product is slick, I feel that it could weigh down curls. I don't know if it truly does. One of my pictures is with light shining on my hair, and the other is in the dark. ... show more

    • Nice product!
Style: 1.7 Fl Oz, New Look
If you're here because you have damaged, dry hair, this is good, but the Joico treatment balm is a LOT better! This product feels thinner than expected, and didn't moisturize my hair as much as I thought it would. However, it didn't affect my color at all and left my hair feeling healthier than before. ... show more

    • Looks like previously used
Style: 1.7 Fl Oz, New Look
the product arrived with the packaging already opened, which raises serious concerns about its safety and authenticity. Additionally, the texture of the mask is highly uneven and appears compromised, as if it had been stored under improper conditions. This makes the product unsuitable for use, and I am not comfortable applying it to my hair. ... show more

    • Not worth the money
Style: 1.7 Fl Oz, New Look
This product is a sample product size. One single use, its not worth it for $12. Smells good though. Not for people with alot of hair (thick hair)
