Smells antiseptic

It's as good as any other conditioner, it's hard to squeeze out of the bottle.

not impressed

Posted by MariamD on Sep 17, 2016

1- It dries my hair . 2- i didn't like the consistency of it , 3- and the bottle is another story , it's hard to get the conditioner out of it . the normal conditioner will do the job. جفف شعري . لم يعجبني قوامه , ومن الصعب إخراجع من العبوة. أي بلسم عادي يؤدي الوظيفة.

I have been using the Thin to Thick shampoo for some time and loving it. I waited until I finished a conditioner from another range before ordering this one. I love it. It is very thick and you only need to use a small amount. I have used hundreds of products over the years searching for the perfect products for my fine, blonded hair. These are the best I have ever used. I am pleased to say that there are no yukkies in these products and they are very economical as you need only use a tiny amount.

Terrible Bottle

Posted by oliews on May 15, 2016

Oh my god, I think my fingers will break one day from trying to get the product out from the bottle everyday. The bottle is too stiff. Besides it doesn't really moisturize well enough for me. Just for the bottle, I am never ever repurchasing it!!!

Thick, like it says

Posted by 5243140551218236964 on Mar 04, 2016

I really like this conditioner, however I have trouble getting it out of the bottle due to the thickness of the product and type of plastic packaging.
