- Asked by AO

- 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

Can I use this product even if my hair isnt colored? My hair is curly but I have really bad frizziness.
- Asked by Gabriella

You can absolutely use the K-PAK Color Therapy Luster Lock Instant Shine & Repair Treatment even if you do not color your hair. However, based on what you’ve shared the Moisture Recovery Treatment Balm (thick/coarse hair) or the HydraSplash Hydrating Gelée Masque (fine/medium hair) may be a better fit for your hair concerns. Hope that helps! ✨💕Was this answer helpful to you

All the products within the K-Pak Color Therapy line are intermixable amongst each other and the best part is that the Luster Lock Treatment can be used either way! It can be used in addition to the shampoo and conditioner OR it can replace the conditioner depending on your hair needs. Since this is a treatment/masque, we recommend applying it only once a week and using the regular rinse out conditioner the remainder of the time.

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...

Very good product
Hair Type Straight Hair
This is a very good product. I like how it makes my hair feel and look. Very manageable
I would and will buy this again!
Hair Type Wavy Hair
I use 40 developer & color my hair. This product responds very nicely moisturizing and making it shine. I will continue to use as a mask. Only to buy a bigger one now I know it really works on my hair.

On my fifth purchase
Hair Type Very Curly Hair
I've used this product for years (my mother used to buy this for me) and now as an adult i still use this for everything. Hair mask, a little for frizz control, for blow outs, for leave in conditioner after a full wash. My hair is healthy because of this product! A little goes a long way, and for someone like me who has long thick curly hair, that's not common. Even if you have straight hair this could work for you, use a little and mix with water and watch your hair transform!
Love this prodiuct!

I've used this product for years. It makes a visible difference in the look and texture of my hair!
YESSSS
I don't know what they put in this but my hair is loving it. My hair is softer than it has been in years. I'm on a hair journey and an under consumption journey. I'm going through a bunch of minis I've collected over the last 3 years and this one will be replacing any and all hair masks for future purchases. My hair has been dyed a lot. I don't use a lot of heat on my hair so I can't speak on heat damage but it was definitely feeling very dry from all the processing I've done. My hair is sooooo soft. I used this ONE time. Definitely purchasing the big guy.
