    Adegen Shampoo

    I have been using this shampoo for just over 60 days. So far I can tell that my hair feels very healthy and seems thicker. My wife says my hair looks thicker!

    Excellent Product

    Best results of any product I’ve ever used in three months I have a lot of new growth in my crown, although I’ve had one hair transplant years ago

    I hope to keep getting more coverage, I was skeptical of this product but I will keep using it, best thing is you can subscribe and they will notify you of your next delivery at this point it’s real easy to delay or advance your delivery date depending on how much you have left, also be super careful with the serum when you put it on the counter make sure to cover out with cap after drawing from it with dropper, I dumped part of mine on my first order, other then that it’s been great using this protocol.

    Hi Dave, thank you so much for sharing your great experience with Adegen!

    We're absolutely pumped to hear about the excellent new growth you've seen in your crown area in just three months - that's great progress!

    Your feedback about the subscription service is really valuable too. We designed it to be as convenient as possible for our customers, so it's great to know the flexibility to adjust delivery timing is working well for you.

    We're excited that you're continuing with the protocol and hope you keep seeing the coverage improvements you're looking for. Your positive experience really means a lot to us!

    Love this shampoo!

    Using the shampoo alone from Aug. to Oct. 1 did nothing. I started using the drops from Oct. 1 to present and still have not seen any changes in. new hai growth. Gave the shampoo a 5 star rating because I love how clean and awesome my hair feels after using it. The first 3 pics are from Aug. and the second set of 3 pics are today, Nov. 30. I have 2 more bottles of drops and shampoo ti use, so hopefully by January, some new hair growth will appear. Fingers crossed!

    Hi Deb, thank you so much for taking the time to share your detailed experience!

    We're happy to hear that you love how clean and awesome your hair feels after using the ARB Shampoo+ that's exactly the kind of feedback that makes our day!

    We completely understand that you haven't seen new hair growth yet after adding the drops in October. Hair regrowth is typically a gradual process, and the timeline can vary from person to person based on various factors including how long you've been experiencing thinning and individual response rates. However after reviewing your first picture with the last one, it looks like there's a bit of improvement in the thickness of your hair.

    Please make sure you are applying enough topical daily. Check out the instructions video when you have some time for assurance:

    We really appreciate your patience with the process and your positive attitude about continuing the journey. Your dedication to the routine is setting you up for the best possible outcomes!

    Sometimes I see a woman in the store who I want to run up to and tell them to get this shampoo. It works.
