I got to use this many times before this review so I can honestly say it works! It worked immediately but I wanted to see if it was one of those products that at first feels great at first use, then flops after. This shampoo is not like that. It works and it is consistent. It says to use 3 times a week I believe, but I would say 2-3 times in my case was just fine. I’ve spent so much money on shampoos for my scalp and the problem never went away. It would stay the same or get worse in some cases. Money literally down the drain. The price to me is worth it when you think of all the money you’d spend on other shampoos that will probably not work. It doesn’t have a perfume-y scent, and that might be why it works. The smell isn’t like your regular shampoos and threw me off at first but it’s a super clean smell and feeling. So glad I decided to give it a try. I didn’t want to spend the money for it to not work but it did!

Best over the counter product in the market

My dermatologist recommended this product over several other options and thus far it is working well.

Dermatologist gave me a couple samples and lathered pretty good and helped itchy scalp, ordered a bottle and seems to me that bottle I ordered is not as thick as the sample., doesn't lather as well, takes more to produce same amount of lather. Been getting emails for 25% off which is more than what the same thing cost with coupon, DUH! Can't recommend this product because if the product keeps getting thinner then I'm the A-hole that recommended it and my recommendation wouldn't be worth anything.

After extensive allergy testing I was given a list of shampoos to try. I bought several that still irritated my scalp and ears. Cln gives my scalp a thorough clean and I haven’t had scalp itching or ear irritation since I began using it.

I have a very sensitive scalp from dermatitis and this shampoo keeps it healthy and a plus is that it’s safe for colored hair.

I love this shampoo. It smell really good. My hair feels so clean and soft. I recommend it to anyone. I’m very satisfied with this product.
