- Q
Is this light enough for fine, longer hair or too heavy?
- Asked by AO
- Official Answer By Joico - Brand EngageHi AO! Thanks for asking. The K-PAK Color Therapy Luster Lock Instant Shine & Repair Treatment can be used on fine hair. We would recommend to keep the product away from the scalp area and focused on the mid-lengths to ends. Hope that helps clarify! ✨💕Was this answer helpful to you

Do you use this in place of conditioner, or do you use conditioner first, then the Luster Lock?

Is this sulfate free?
- Asked by Juli
- Official Answer By Joico - Brand EngageHi Juli! Thank you for your question. The K-PAK Color Therapy Luster Lock Instant Shine & Repair Treatment does not contain sulfates. Hope that helps clarify! ✨💕Was this answer helpful to you
- Q
Why is isopropyl alcohol in the formulation/ingredients? What function does it serve?
- Asked by I love Tab
- Official Answer By Joico - Brand EngageHi I Love Tab! Thank you for your question. Alcohols are used for a variety of reasons and not all alcohols are the type that can be drying to hair. The Isopropyl Alcohol comes to us as part of a conditioning ingredient. During manufacturing and the heated phase of the formulation process, there is little to none left in the formula to have any drying effect once manufactured. Hope that helps clarify! ✨💕Was this answer helpful to you

You've Been Warned!
This is the worst hair product that I have ever used. I used it as a hair mask in the shower, got out of the shower, dressed, did my makeup, and as soon as I went to dry my hair I discovered the disgusting mess that was my hair. It was so greasy and weighed down that despite my efforts to dry it, it...

Hair is much healthier now!
Greatest product in hair history
Hair Type Wavy Hair
Oh my gosh, this is like a genie in a bottle for your hair! I use this once a week when my hair needs a little boost from all my heated tools, flat iron, hair dryer, curling iron, etc. This product really gets rid of the frizz and makes my hair look like I got blow out from a salon. Super smooth and healthy looking. It's a little pricy but definitely worth it. I wouldn't use it every wash but at least a couple times a month will definitely bring your hair back to life.
Amazing Treatment

I love the K-Pac Color Therapy Luster LockTreatment and so does my hair. After each treatment my hair is frizz free, looks super healthy, and is so soft and manageable. I normally wear my hair up at work, but I love the way it looks and feels now, and the compliments I get are awesome.
Improves hair health and condition!

I LOVED this conditioner!! It smelled amazing, and the scent lasted until next wash without being overpowering. I was given this product a long with the matching shampoo to try for free in exchange for my review and I am so grateful to have added a "must have" to my list of hair products!! My hair type typically requires a trim to get rid of any damage as I have never found anything that really works to improve the appearance and health of my hair, but after a few weeks, my hair is healthier!! I was saddened to squeeze my last drops out and said to myself that I needed to get some more. I did find that while the pair made my hair health improve, I needed to wash my hair more often than usual. Through trial and error, I was able to narrow it down to the shampoo as the culprit as I could use the conditioner with another shampoo and resume my usual wash routine, but the with the two together, the hair health benefits in my opinion mostly negates the problem of needing to wash more often. All in all, I really really loved this conditioner and will be buying it in the future!
