   Decent hair hair shampoo 2nd purchase.
   Great product does what it says. Doesn’t dry hair out. I still use conditioner to tame hair. I have long male hair shoulder length. Happy with purchase X2.

   Really helps with my skin infection
   I have a skin infection on my head. It appears that I got this from wearing the same bicycle helmet without proper cleaning of the helmet. My dermatologist tells me that he sees this on the knees of young women who play sports such as soft ball with knee pads. It is almost impossible to cure this infection but this shampoo really helps hold it back and reduce outbreaks. It is very sudsy and a little goes a long way. It has no particular scent but does leave my hair a touch dry.

   IT IS ACTUALLY WORKING! (for me)
   3 weeks in and there is tremendous growth around my front hairline, where I was experiencing hair loss for the last 2-3 years. I never do reviews, but I thought that the uniqueness of my case might help others that are dealing with the same issue.I saw somewhere that carbonic acid shampoo could help with thinning hair, especially in areas of your scalp that get extra dirty. I wear hats, especially when i work. I often have a set of dirty hats (often very dirty), that I use for various outside jobs, from construction, gardening, beach and river. I’m in my mid-40’s and I have a lot of hats for every occasion. Mostly for outdoors, so they get dirty.Old dirty hats!I’m going to say, that I believe my hair loss was caused by my use of dirty hats. The shampoo started working immediately in that area. I saw growth only a few days later. Seriously!It’s smells like tea tree oil, which I like, but it is kind of a “hippy” scent.I would have been the first person on either side of my family to have a reversing hairline. I knew there had to be something else to it, and I’m fairly sure that I found the answer. I’d imagine that being middle aged, with common stress, played some part, but to have seen how quickly it worked, I am convinced that the hair pores were clogged somehow. I dont think I would have pursued my hair loss issue any further, had I not found a product that worked immediately. It’s not a big enough of a deal to me, and I was certain that it was just stress related. So I’m glad I came across this particular carbonic shampoo and gave it a try.I wanted to share my story (I rarely do reviews), and hopefully others with similar stories can find this as an impressively quick and relatively cheap option. Hopefully it works as well for others. Good luck to you.Great product, highly recommended!

   does work as a volumizer, doubt it will do much for bald areas
   “Title” pretty much represents my complete thought on this product. Still, I haven’t used it very long so the “jury” is still out on how it “might” work. It definitely increased “hair volume” (thickness of the hair you already have) and it definitely cleaned my hair. I personally feel, I’ve may have had better results though, with “Salicylic acid” based products… (like Denorex – at least I don’t seem to be losing as much hair as I was using Denorex) I bought this more for the volumizing which seems to work for that purpose for sure, “for me.” Your “mileage” may vary on both items… (regrowth and volumizing)

   It works!!!
   Edit to my previous review:Regarding hair loss I noticed at the nape of my neck I don’t know why that occurred; however, I can assuredly say it was not from using this product. This is the BEST shampoo I have ever used. You only need a nickel sized amount and boy does it lather! Each 16 oz bottle lasts at least 3+ months so it is well worth the money. It has changed my hairline and my hair has grown back and remained with consistent use of this shampoo. I will never use another shampoo that’s how much it works, and how much I love it. I have used this as my only shampoo for about a year, and am only on my third bottle.I have used consistently for 3 months and I can say this works! Honestly, I was astonished at how well it works. I have had a horseshoe shaped bald spot primarily on the left side of my temple for years. I’ve used collagen which would help temporarily grow fine hair back in this spot; however it wouldn’t completely fill it in or regrow my full hairline.I was washing my face the other day and put a headband on and noticed my hairline went straight across so I took a picture to send to my daughter and she couldn’t believe it. She’s seen the difference from when I had lost my hair in that spot, when I tried collagen which by the way my hair would fall out once I stopped using it, and to using this shampoo. Now, I know if I stop using the shampoo the same will happen as when I stopped the collagen, but these results are much better AND easier to use than adding collagen to my food/drink. I must add; however, I’’ not sure if this is related to the product, but nothing else has changed in my life e.g. diet, medications, stress, etc., but the hair at the back of my neck has reversed and thinned out considerably! I am going to continue to use the product ONLY at my temples where I had hair loss and use another generic shampoo at the back to see if this product was somehow the cause of that hair loss. I’ll update once I have more news.
