Kiehl’s Ultimate Thickening Shampoo Review


Many people think that hair thickening is a problem that mainly affects older men and older women, while there is some truth to that hair falling out and thinning hair can affect both men and women of any age.


I’m 25 years old girl who suffered major hair thinning. As a child, my hairs were extremely thicker but as I grew up my hairs become progressively thinner. My extremely thin hair that weighs down at the ends like if I pull my hair up into a ponytail I will have bald streaks showing. I have to make sure my scalp isn’t showing and it’s so embarrassing. I often get depressed because of the state of my hairs. One of my friends recommended this Kiehl’s Ultimate Thickening Shampoo to me to help my hair grow back.

I was really excited to try this product& it seemed even more excited to prove its effectiveness to me. Noticeably thickening strands of my hair after just one wash, my hair just felt different. I can’t believe how quickly it worked & thought it was too good to be true. My hair didn’t lose its thickness after I continued using it but I wouldn’t say that it strengthened my hair completely. I also notice that my hair is much more manageable in ways that my naturally wavy hair is less messy and there’s definitely a lot more shine whether I use conditioner or not. From the first wash, I could see a difference. I love the way this makes my hairs feel silky and it adds loads of shine.

I have enjoyed this product. But, you can’t really know if the Kiehl’s method will be right for you until you try it.
