Carbonic Acid Shampoo for Men and Women with DHT Blockers - Made in USA - Stimulates Hair Growth, Scalp Exfoliator, Sulfate Free Shampoo with Biotin and Tea Tree Oil (16 Fl Oz)

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.

Excellent, no more oily scalp. It deeply cleans.

Results take a long time

I have used this product for over a year and not seen any improvement with hair thickening or with hair loss. Not likely to continue.

I've used it all in my life - all of the head and shoulders anti dandruff and expensive shampoos and conditioners trying to fix my itchy and sry scalp and I finally found the solution. This stuff makes my scalp feel great and I hope that the carbonic acid will stop my receding hairline over time. Based on the fact that it stops my front hairline from itching tells me that I am not scratching my hair away and that my hair follicles are likely a lot happier.

product works I've used this for 12months now and defiantly noticed new hair growth since using this shampoo I recommend this product

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!

This second purchase of the shampoo did not work like the first product. The first bottle was a thick liquid that suds up really well on the 2nd treatment whereas this second bottle was a thick gel and did NOT suds up at all...hair did not look or feel clean. My husband and I both use this product but no more. VERY unhappy with the experience second time around and on top of that the product cost quite a bit more than original purchase just a few months ago. REVIEW UPDATE! After the use of about 1/3 of the bottle of shampoo, the consistency and composition of the shampoo became more liquid like the first bottle and began to perform like our first experience. The shampoo is now an effective product. We don't know why the product was defective at first but is fine now.
