Is this shampoo free of Sulphates such Lauryl Sulphate etc that most shampoos have? I have been using this shampoo for a number of years by now and came across information that Sulphate shampoos are damaging to hair follicles and thus may be detrimental for even normal hair growth. Thanks

Is your Ultimate Thickening Shampoo safe for colored hair? I have used Nioxin, Bosley and another shampoo and none really have been 100% effective for thinning hair. Thank you.
A shopper on Apr 20, 2012
Best Answer: I have colored hair and saw no evidence of fading or problem of any kind. However I saw no regrowth of hair. I wasn't fond of the scent, or lack thereof so didn't order another bottle. Perhaps I should have to give it more of a chance to work.

does your product contain any type of toxin such as Phenoxyethanol?

I have very fine, color treated hair, and I'm not sure whether to use the thickening or the volumizing shampoo.Also, do either of these shampoos leave a residue after continuous use?
A shopper on Jul 22, 2014
Best Answer: I also have VERY fine thinning color treated hair--the thickening shampoo really works BUT it is also drying. I usually alternate between moisturizing & thickening shampoo/conditioners. If there is a residue/build-up, the condition is resolved when I use other shampoo/conditioners. Hope this answer was helpful.

I have an oily scalp. Is this shampoo suitable for my hair type? If not, what would you recommend?
A shopper on Feb 12, 2013
Best Answer: Yea my scalp is pretty oily too and I use it often. I wouldn't worry about it. It works fine. As far as making your hair actually thicker...the verdict is out on that. I've been using it for 2 years and I think it's one of the better shampoos you can buy today. You only need a very small dab of it on your fingers and rub. I used to think I needed to pour it on like with regular shampoo. This thing lathers up really well. You can't go wrong with it.

Do you need to use conditioner with this shampoo? If so which one
A shopper on Dec 3, 2013
Best Answer: I do not use a conditioner with this shampoo. If you are used to using one I am sure that it will work fine with it but I find that this shampoo is gentle enough for both everyday use and not requiring a conditioner to leave hair feeling soft or without tangles. But I must say I probably have less hair than you.

does this dry your hair out if your hair is naturally curly/frizzy?
A shopper on Oct 22, 2013
Best Answer: I have been using this shampoo for several years. I love it !!!!

It does not seem to dry my hair out, but sometime I just shampoo and let my hair air dry. That is, not blow dry it if I am not going anyplace. When I do that I notice that I do see a few small strands of hair that seems curly. And believe me, I do not have naturally curly hair !!! But, if you blow dry your hair every time you wash it, I don't think you will have a problem!


I hope this answers your question.

Kelly on Jan 20, 2014

I was just wondering if you buy the shampoo to thicken your hair what condition do you use?
trish r on Feb 22, 2015
Best Answer: Kiehls sells a conditioner to compliment the shampoo. Personally I use a conditioner that has no parabins or other additives when I am out of Kiehls ultimate conditioner.

My hair is fine and fragile and color treated. Most thickening shampoos dry out my hair. Does this shampoo leave your hair soft and moisture?
A shopper on Jul 30, 2014
Best Answer: Yes! This shampoo is fantastic. I have long, thin, color-treated (and regularly heat damaged) hair, so I'm wary of any shampoos that might dry out my hair further, or leave that overly squeaky-clean feeling. This shampoo is extremely gentle and moisturizing. I use it with the formula 133 conditioner/grooming aid, and my hair feels soft, totally detangled and not at all greasy. I hope this helps!

Is this shampoo still sold under this name ? I went to Nordstrom to buy it and they told me it was now under the amino acid name and sold me that type instead.
A shopper on Nov 27, 2014

The Amino Acid shampoo is a completely different shampoo. The name is still the same.

Why are your Ultimate Thickening Shampoo bottles made with such brittle plastic tops? My last two bottles have had their tops shatter on impact when I drop them in the shower, leaving dangerous sharp shards of plastic everywhere! This does not happen with similar flip-top mechanisms in other brands. I'm NOT happy about this...

Both my daughter and myself have thin hair on the crown have used other products how long would it take to see some results from this shampoo? the brown bear
A shopper on May 12, 2013
Best Answer: I think this is a very nice shampoo. I have tried other brands and they were too drying. I use the rice and wheat conditioner before shampooing. I think there is a nice body that this shampoo provides without leaving any residue.
