effective protein treatment
I 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 min...

Not moisturizing
Earlier 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 we...

I will never buy this product again.
Verified Buyer
This product was runny and separated. I shook it and it made no difference. It looked like coagulated milk. It has a foul odor to it. Not like the other JOICO products I have purchased. It also did not condition my hair at all. It left it drier than before using and tangled.
Great product
This hydrating and hair-saving reconstruction has been great to me! You don't have to leave it in for long, and it washes out easily. It also smells fantastic! The formula helps reconstruct your hair from the inside out. It's a great asset, especially if you color your hair.
Improved elasticity but dried out my hair.
Verified Buyer
This reconstructor improved elasticity but dried out my hair. I have color-treated hair, so I have to use a good mask to prevent breakage. I only leave it in for 5 minutes. Any longer than that sucks every bit of moisture out of my hair. IT DRIED MY HAIR OUT SO MUCH THAT I COULDN'T EVEN GET MY FINGERS THROUGH IT! If you're looking for it to moisturize your hair, don't buy this. Itll do just the opposite. This product is also way too expensive. The only reason I still buy it is because it improves the elasticity of my hair better than others I've tried so far.
Game changer for dry damaged hsir

I have only used 2 times, but WOW! Hair has less heat damage and is so soft
Not moisturizing
Verified Buyer
Earlier 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. .

- Q
How long does the proteins last? Does it wash out? Is it permanent
- Asked by Anna
- Official Answer By Joico - Brand EngageHi Anna! Great question. The proteins in the K-PAK Deep-Penetrating Reconstructor are not permanent. For best results, we recommend using the Reconstructor once a week. Hope that helps clarify! ✨💕Was this answer helpful to you
- Q
How long does proteins last in relaxed hair? It it permanently? Or temporary? How does the product differ from bond builder treatments like k18 and Olaplex? What's the best way to use this product ? Do I need to use conditioner after it?
- Asked by Anna
- Official Answer By Joico - Brand EngageHi Anna! Thank you for your question! The K-PAK Reconstructor is not a bond-building product. It addresses protein. Joico uses all 19 amino acids in the correct order and at the proper weight and size to go into the hair to reconstruct from the inside out. If the hair does not need a specific amino acid, the hair will not accept it. The amino acids fit like puzzle pieces in the hair. There is no possibility of over proteinization or over keratinization with any Joico product. The K-PAK Reconstructor is best used after shampooing with K-PAK Reconstructing Shampoo. It is also recommended to follow the K-PAK Reconstructor with the K-PAK Intense Hydrator Treatment for 5 minutes. For best results, it is recommended to use the K-PAK Reconstructor 1x a week. Hope that helps clarify! ✨💕Was this answer helpful to you
