## Questions & Answers

**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.

### ⭐⭐⭐⭐⭐ Bye bye breakage! Joico Reconstruction kit really works!
*by N***A on July 14, 2023*

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!
