I have spent the last 12+ years colouring my hair. I made the mistake of begging my mom for highlights when I was 12, to which she complied & from there, I've been colouring my hair non-stop. I have naturally straight hair & am so surprised it hasn't all fallen out of my head. I've done it all...every colour you can think of as well as the harsh transaction from going black to blonde twice. I've stripped my hair twice & have always had to cut so much off because it was just simply dead. I've been trying to grow my hair out for about 2 years now & have had lots of success thanks to this hot piece of hair re-constructor. The dye I'm using now is a demi, which I do believe helps reduce damage, but this product has brought my hair back to life. I still have to manage my split ends & do a routine trim every 3 months, but for the first time in a long hair looks & feels sooo healthy! I love this product. I will continue to use it for as long as I need to :D

Total HG product that has brought my hair back from the dead more times than I can count. I usually put off buying it because it is so pricey. But my oily, color treated hair has been a real challenge lately-in addition to the usual frizz and dullness, it has been breaking off a lot. I bought some Redken Anti-Snap and their new breakage line-nothing worked. I was really concerned about the amount of hair I was losing, so I bit the bullet and bought some KPak (shop online, there are some good discounts to be had.) All I can say is wow. The breakage issue is gone, my hair is smooth and shiny and actually looking good for the first time since I don't know when. I am definitely going to keep it on hand from now on.

This product is AMAAAAZING! but you can overdo it.

For reference -- my hair is 2A/B (wavy), normal porosity, fine/medium, plentiful, uncolored, past shoulders with long layers, in good condition, and getting wavier as I age. Grays are just starting to show up -- my new hairdresser says she saw maybe 3. My hair has too much slip (not much texture). I'm the "have trouble keeping a rubberband in that hair" girl.

I'm a product junkie, always looking for products to resist my hair's nature of wanting to droop. It's not that I want big hair; I just don't want my hair laying flat at the root. I'm working myself away from silicones, parabens, sulfates - though this product does have parabens (see ingredients below) and trying to eliminate hairspray entirely from the regimen. I've been sampling any number of sulfate-free products and am pretty well devoted now to DevaCurl.

So, the routine is to wash/co-wash, condition, K-Pak and wait, rinse, use a deep conditioner (Biolage Conditioning Balm) with extra attention on the ends of my hair. I can't tell you what a difference this makes! My hair is still really silky, but it is sooooo well-behaved. It requires minimal styling (drying) and no hairspray. And it stays. It stays wavy, it stays full.

I encourage anyone, regardless of hair type (straight to very curly) to check out Those folks may or may not have your hair assets or challenges, but they know hair and gave me great insight to how to deal with mine - now that it's changing (?)

A few words to the wise about this wonderful product. First, it's not a conditioner. Second, it's possible to overdo a good thing -- I think I spaced my last use (about 5 weeks ago) 4 days apart, and that left my hair a bit dry. I vowed not to repeat that mistake, put the tube in the back of a cabinet, and forgot about it! I couldn't figure out why I was having to fight again with my hair -- then, doh, remembered this. I think I need to be on an 10-day schedule with this. Bottom line: I'd encourage you to check out naturallycurly to explore your hair type then, if you think reconstruction might help you, try this!

I am in love with the K-Pak Deep-Penetrating Reconstructor for several years now. It is my life-saver. I have thick black hair with double-process bleached blonde highlights. It brought my fried straw-like hair back to life.

Just re-purchased this product, the previous bottle lasted me about 6 months using about 1x a week. Makes my damaged hair so silky i prob dont even need to follow up with a deep-conditioner like with most protein treatments. I find it hard to tell whether protein makes my hair any stronger, it was bleach-fried..but managed to look quite healthy after using this stuff. cost about $27 in Oz.
Look forward to using this product...would recommend!

after years of dying, straightning, curling and blow drying my hair combined with not knowing how to look after it properly, my hair was in very bad shape dry, brittle, doll and the ends would snap off all the time. I have been using this along with the shampoo conditioner and hydrator for 2 months now and my hair has improved so much i am so hapy i purchased this! i have read some reviews saying this is really bad but the same people refer to this as a conditioner... THIS IS NOT A CONDITIONER, its a protiene treatment for people who have chemically and heat damaged hair... and it works wounders, nearly finished my first tube and about to purchase some more, this is a product i feel i will never stop using.

Awesome stuff. I've used A LOT of masks in my hair to try and get it just a little healthy feeling. From Aveda, Redken, Alterna, nothing seemed to actually get my hair feeling healthy after the abuse I put it through. Then I tried this. It's light weight enough that you can get it through your whole head of hair, but sinks in deeply and leaves moisture you can feel without a greasy feeling after. My hair is fine but with lots of it and this has never weighed it down and has helped it bounce back to life after bleaching, stripping, dying, cutting, etc...I will always keep this in my rotation.

Had chemically processed my hair in recent history before going back to my natural hair color and deciding to stay that way.
This is great for maintaining the integrity of my hair in between my Nexxus Aloxxi Polymedic Emergency Reconstructor treatments. K-pak leaves my hair feeling softer than Aloxxi, but Aloxxi is definitely superior to K-Pak in terms of reconstructing.

This product is better than I even expected! I only use it about once a week, and I rinse my hair with apple cider vinegar beforehand to get rid of any build up. My dull, horrendous ends were never ever shiny, and they now ARE! My hair feels lighter, healthier, and looks soo much nicer! I'm very happy with this product line, I also use the k-pak daily conditioner, daily leave-in, and have used the k-pak shampoo and intense hydrator. All fine products! I highly recommend this stuff for dry, damaged hair.
For reference, I have long, wavy, fine blonde hair. I dyed it to a dark blonde about 3 months ago, but the color has almost fully washed out back to my original blonde. However this totally made my hair dull and dry in the process even though it was professionally done! I'm never dying my hair again! Anyway, Joico has really saved my hair!
