FAQ's

Q: Will the products help protect against flat-iron damage?

A: Absolutely! Whether the culprit is over-zealous heat styling, chemical processing, or even harsh environmental factors, K-PAK safeguards against damage, dryness, and dullness.


Q: Will the Clarifying Shampoo strip my hair color?

A: 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.


Q: Do you have a deep-conditioning treatment that won’t weigh down my fine hair?

A: 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.


Q: My hair is fried from too heavy highlighting. Which product is right for me?

A: 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.

Q
How long does the proteins last? Does it wash out? Is it permanent
Asked by Anna
Official Answer By Joico - Brand Engage
Hi 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 Engage
Hi 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
Q

Asked by Ashley
Official Answer By Joico - Brand Engage

Q
Can this be used on permed hair?
Asked by Spooky
Official Answer By Joico - Brand Engage
Hi 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 Engage
Hi 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
Q
Can this be used to fix hair that is too soft? I have very fine flat hair and recently it's been so flat and almost too soft after trying multiple different shampoos to try to add body. Now it's just a limp flat mess. I read that protein treatment is what is needed for too soft hair, is this that kind of protein treatment?
Asked by JS
Official Answer By Joico - Brand Engage
Hi JS! Thank you for asking. The K-PAK Reconstructor may make your hair softer. We would recommend to try the K-PAK Clarifying Shampoo once, to help eliminate some of the previously used products on your hair. Then use the JoiFull Volumizing Conditioner. For your regular routine, we would recommend the JoiFull Volumizing Shampoo, Conditioner, and Volumizing Styler. If you would like to add styling products, we would recommend the Rise Up Powder Spray and the Body Shake Texturizing Finisher which are excellent for creating volume with styling. We hope that helps clarify! ✨💕Was this answer helpful to you
Q
Is this for very dry hair?
Asked by Kathy
Official Answer By Joico - Brand Engage
Hi Kathy! Thank you for asking. For dry hair, we would recommend the Joico Moisture Recovery Collection for Thick/Coarse Hair or the Joico HydraSplash Hydrating Collection for Fine/Medium Hair. 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...

Hair Type Wavy Hair

My hair is thin and I don't have a lot. I have a body wave added for volume and it is color treated. I have four different Joico conditioners, and I alternate using them. The Reconstructing Conditioner is by far my favorite. I use it once a week. It doesn't weigh down my hair at all, and gives it such a healthy texture and look. I'm so glad I finally found the perfect combination for my hair in Joico products.

Bottom Line Yes, I would recommend to a friend

From Iowa

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!
