- 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

- Official Answer By Joico - Brand EngageHi Spooky! Thank you for asking. The K-PAK Deep-Penetrating Reconstructor is safe for permed hair. With any permanent curl treatment, we would recommend waiting 72 hours after the service before using. Hope that helps! ✨💕Was this answer helpful to you
- Q
Can this be used daily?
- Asked by Laurel
- Official Answer By Joico - Brand EngageHi Laurel! Thank you for your question. The K-PAK Reconstructor would be a weekly deep-penetrating treatment. The K-PAK Daily Reconstructing Conditioner would be for daily use. Hope that helps clarify. ✨💕Was this answer helpful to you

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...

Brazilian Blowout in a bottle!
This has been a staple of mine for decades. Ive spent mega $$$ thinking newer must mean better. While this is not trendy or overhyped on tiktok, there's nothing like this out there. Stakes claim to the old adage - they don't make 'em like they use to! But Joico does - Probably why they're still around. It's texture snd smell are unique these days - but all of the classic true keratin treatments were like this. It works wonders for taming frizz - An at home Brazilian blowout!

I want to love it.....is it banana smell or perfume?
Hair Type Wavy Hair
I have a lot of fine 2b-2c curly hair, which for the past few years has gone lifeless and unhealthy. I bought a tube at a different local discount store and the smell was completely different to what I used to buy that everyone says smells like "bananas". It literally revived my hair after 1 use, but the smell is horrific and is giving me constant allergies and sinus issues. I hadn't used it for nearly 20 years. My bottle smells like an awful strong perfume. I'd be happy to know it should smell like bananas! I will be sniffing it out at Ulta soon. lol
fave hair product ever!!!
i have been using this once or twice a month for over 15 years!! it is a life sacer for my curly, bleached hair. if i go a few months without it, my hair gets super dry and tangled. i love the banana scent, and how my hair feels afyer using it!!! some people aren't fans of the texture of it, it sometimes comes out of the tube feeling kind of lumpy, but that is how it has been for years, so do not worry. if that makes you think you got a bad batch or something, you didn't! i don' t leave reviews often, but i just had to about this stuff, it is amazing and worth the price!!
