Thankfully I only bought this shampoo in a sample size, along with the conditioner and treatment oil. My hair is a bit dry from colouring but not very bad. This shampoo did no better than a bottle of 2 euro shampoo from the supermarket. It was alright but definitely does not justify the price. For the price of this stuff I would expect to get a 'wow' result, it only gives a 'meh'. Will not be buying the full size bottle. If only I could find somewhere that sells Colet products, best shampoo ever but I can't find it any more.

For hair color staying power, this shampoo did its job. For just a shampoo, overall cleanliness, moisture, and how it made my hair feel, it was so average. I'm an every-other-day hair washing kind of girl, but this made my hair greasy quickly, especially if I styled it. I am a fan of Joico products generally, but this just didn't do it for me.

So I ruined my hair with cheap dye :( I can't afford to have my color put in at a nice salon every 8 weeks, so I started using box color. Switched to a brand of color I thought I really liked, but realized after a few uses that the stuff was frying my hair - which I'd been coloring for years with no issues :(

I tried baking soda and vinegar, which made my hair wonderfully manageable but pulled out the color. I tried drugstore stuff, which made my hair tangled and so that it quickly got greasy.I tried natural brands and didn't care for several of them. Finally, I sucked it up, went in for a haircut and asked the girl what color-protecting shampoo she'd recommend.

She raved about this one and I walked away with the gift pack of the small bottles, to try it. The price isn't terrible - I honestly expected worse for high-end stuff, and I don't shampoo every day so I figure it will last. After just one use, the texture of my hair was SO improved. Silky, soft, snarl-free and light/not weighted down. I waited a few days before using again to see if it would get super greasy in between washes like it used to, but it doesn't! My hair feels wonderful and looks great. I will keep using and probably go back for bigger bottles next time. I find the smell pleasant, fruity and not offensive at all, and I'm sensitive to a lot of fragrances so that's saying something. I'm excited to keep using this.

This smells wonderful and has a pearlescent color. It gave a creamy lather but left my hair feeling clean after I rinsed it out. For reference, I have curly and medium textured hair that is prone to frizziness and can get dry during the winter months. The regular K-pak shampoo left my hair feeling brittle and flyaway even though my hair adores products with protein in them. This is more pleasurable to use. My hair comes out soft with more defined curls and shine. Bought the gift pack at my local beauty supply and very happy I took the risk. Paired with the matching conditioner, it does a good job. I see less shedding in the shower.

I am a bit torn....My biggest con is the smell. It has the scent of those sunless tanner lotions. Its too much at first, but I guess you get use to it. I'm going to be honest, its way overpriced ! For something that costs so much you should be saying "WOW my hair is amazing!!" I just expected a bit more of quality.

My biggest pro is the shine it has added to my hair and it has definitely made my blonde streaks sparkle.
I got this on sale and I use it when I get my hair highlighted. It lasts you a long time.

Unless its on sale, I am not sure I would buy it again. Again its not awful, but I wouldn't jump to say its spectacular just yet.

I picked this up on a whim at Marshalls for $10. 16 oz bottle with a pump.

It cleans nicely, without stripping or overdrying.

It does contain amodimethicone, which for now is OK for my hair, but in different weather or if used as my sole shampoo would give the dry hair, greasy scalp, and other negative effects noted by other reviewers here.

ETA: After using this 3 consecutive days, instead of sporadically, my scalp began to get greasy and itch like crazy. For me, I know this is due to the amodimethicone content being too much for my scalp. I missed it when I first read the ingredients, because it was all the way at the very end. So if you are 'cone -sensitive, beware.

This shampoo works great, it lathers and cleans well but also moisturizes and detangles. However, I can't stand the smell. It's way too strong at first it smells like a cheap laundromat and then like men's cologne. So therefore I won't be using it, the strong smell gives me a headache. But if you like the smell this is a really good shampoo! Maybe I'll try the regular k pak, I don't mind the fruity scent of the regular k pak shampoo and conditioner.

I have been using the K-Pak Color Therapy for about 2 weeks now and love it, although I noticed a difference after the first use. Very high quality, silky, lathers nicely and smells wonderful, like apples. I also use the accompanying conditioner, but I find I don't have to use it every time. Love this stuff! I should note that I bought my stuff from a salon not off ebay or Amazon.

For reference, I have fine highlighted and low-lighted hair. I blow dry and flat iron everyday.

So I bought it on Amazon where it was much, much cheaper than retail, and I'm really glad I didn't spend more than $15 for the shampoo/conditioner set.

The shampoo took as much shampoo for my above shoulder length hair then regular shampoo took for my waist long hair. When I was done and my hair was dried, I would often have to put dry shampoo in because my hair was still greasy. Afraid it was my other products, I did one where I only shampooed and did nothing else and was still greasy. AND THEN I got zits ALL OVER my scalp, hairline, neck, and chest. Biolage gave me the chest and back zits, but the scalp and neck were new (and gross and painful).

I have really fine hair that tends to be greasy. Admittedly I don't have problems with dry or problematic hair, I try to use color care products as preventive measures. If you're looking for something protective/preventative, this might not be the product for you. Maybe it's just better for repair work.

Oh - and the lids kept coming unattached.

This is my HG shampoo and conditioner! I will never use another shampoo/conditioner ever as long as I am coloring my hair! I cannot rave enough about it. It makes my coarse, damaged, bleached, and dry hair much more manageable and I can feel the transformation each time I use it. It smells really pleasant and doesn't make my hair feel too overly moisturized or greasy. You can great deals on the liters at Ulta...but I just read that the keratin breaks down after about 8 months in these products which probably explains the crazy sale prices.
