    1. How to use Dualgen-15 NO PG?

     A: It is a topical solution. It should be applied to the hair loss area using the dropper that comes with the product. Use no more than 1 mL per application.  Dualgen-15 is recommended to apply once daily in the evening in conjunction with a lower strength minoxidil product such as Dualgen-5 or Essengen-5 once daily in the morning. You can wash your hair 3 hours after applying the solution. Or you can leave it overnight and wash your hair the next morning.


    2. How soon can I see results?

     A: It usually takes 3 to 6 months to see hair regrowth. Some people may see improvement in as short as 1.5 months. If  you do not see any improvement in 6 months, this product is probably not for you and you should consider stronger solutions such as Dulagen-15 NO PG Plus.


    3. Will I have any shedding if I have used regular 5% minoxidil for quite some time?

     A: Most people who switched from regular 5% minoxidil to Dualgen-15 do NOT experience minoxidil shedding. About 20% of such users have initial shedding but recover later because of strong regrowth.


    4. I noticed that you have another product called Dualgen-15 With PG. How is it different from this product?

    A. We initially only offered Dualgen-15 NO PG.

    Later we added Dualgen-15 With PG  in response to the request by our customers.  

    These two products have the same effective ingredients (15% minoxidil, 5.0% azelaic acid, 0.8% ABN complex, 0.025% retinol, and 0.001% caffeine) and are equally effective.

    The only difference is that DualGen-15 NO PG uses glycerin, whereas DualGen-15 With PG uses propylene glycol (PG) as the delivery vehicle.

    The use of glycerin in DualGen-15 NO PG eliminates any scalp irritation caused by propylene glycol that is seen in ~10% users.

    However, it also slightly slows down the drying time.

    So if you know you are allergic to propylene glycol (PG), it is best to use DualGen-15 NO PG. Otherwise, you should consider DualGen-15 With PG.

    5. What is the advantage of Dualgen-15 NO PG over readily available 2% – 5% minoxidil products? 

    A. Dualgen-15 NO PG has at least 3 advantages:

    1. Higher strength of minoxidil means better hair regrowth: Minoxidil displays a dose-dependent effect with higher concentrations, improving the responsiveness and greater regrowth of hair.

    The higher the effective dose of minoxidil, the better the result is. That is exactly the reason why 5% minoxidil gave better results than 2% (see below).

    2. More skin friendly. This product is free of propylene glycol (PG). PG causes skin irritation among 20% users of the regular 2% and 5% minoxidil products.

    3. Tackle hair loss issue by multiple mechanisms: Regular minoxidil products have only minoxidil with nothing else. They lack of azelaic acid (natural DHT blocker), ABN complex (vital hair nutrient), retinol (minoxidil enhancer), caffeine (strong hair growth stimulator).



    6. Is Dualgen-15 safe?

     A:  Some sellers who offer so-called natural hair regrowth products would tell you minoxidil is full of side effects, thus you should buy their home-made "scientifically" formulated product.

    Please be advised that minoxidil is number one hair regrowth product around the world. It is available without prescription in many countries.

    Large scale clinical study showed that 5% minoxidil solution has only 1.2 ng/ML of minoxidil in the serum, while minoxidil concentration has to be greater than 20 ng/mL to give systemic effects.

    Thus, there is more than a 16-fold safety margin from the use of 5% topical minoxidil, and 5-fold safety margin with the use of a 15.0% topical minoxidil solution.

    Nonetheless, it is a minoxidil solution, thus people are recommended to be vigilant about all the possible minoxidil side effects when using this product.


    7. Can you tell me the solvent composition of your product?

    A. The solvent consists of Purified Water, Ethanol, and Glycerin. We can't give the ratio of the solvents as it is our trade secret.

    We have done extensive experiments to optimize the solvent composition to ensure our products have the optimal absorption, usability and effectiveness. 


    8. Is a glycerin based formula less effective than a propylene glycol based formula with the same minoxidil concentration? 

    A. No. Both glycerin and propylene glycol are pharmacologically inactive ingredients in the minoxidil products.

    They are used in minoxidil solutions as solvent so minoxidil can be in solution form.

    In addition, their slow rate of evaporation allows the effective ingredient minoxidil to form a thin film on the scalp for continued absorption.


    9. Does this product harm healthy hair? 

    A. Not at all. Although the exact pharmacodynamics of minoxidil is not well understood, the effect of minoxidil is to safely promote growth and to maintain maturity of the hair follicles.

    These effects are most observable in hair follicles affected by male pattern baldness (MPB).


    10. Why is azelaic acid added to the Dualgen-15 solution?

     A: There are two main reasons why  a high strength minoxidil product  is usually compounded with azelaic acid:

    1). It has shown in vitro study that azelaic acid is a strong DHT blocker. It reduces the DHT concentration in the scalp to reverse genetic hair loss (male pattern baldness) that is currently believed to be caused by the excessive DHT in the scalp.

    2). The other reason that is not so well known to the general public is that it actually helps the absorption of minoxidil. Minoxidil is a base, which likes to grab a proton in a solution and become an ionic molecule. Our skin does not absorb any ionic molecules (a molecule that is positively or negatively charged) very well. When azelaic acid is added, it will form azelaic acid-minoxidil complex, which is a neutral molecule and can be absorbed by our skin or scalp much more efficiently.


    11. I have heard high strength minoxidil is not stable. Is your product stable?

     A: The stability of a high strength minoxidil product like 15% minoxidil depends on how it is compounded.

    If properly compounded, it has pretty decent stability. We have done stability study. It shows that It is stable for at least 3 years.

    Please be advised that all minoxidil products should be stored at room temperature. Crystallization may occur if it is stored in a refrigerator, which is particularly true for high strength minoxidil like the product listed here. We have noticed that crystallization does occur occasionally during the shipping in cold days. 

    If crystals are formed in a minoxidil solution, you can warm your product bottle in hot water and shake the bottle for a few minutes to dissolve the crystals.


    12. Do you have any before and after photos to show it works?

     A: We have many such photos submitted by customers. 

    Below is one example of using Dualgen-15 NO PG for six months.

    You can view more results here  (MinoxidilMax Before and After). 

    You can also read the customer reviews shown on each product page.

    13. Do you have anything stronger than Dualgen-15 NO PG?

    A. Yes. We do have stronger solutions available. 

    Please check out our Dualgen-15 NO PG Plus, and Dualgen-15 With PG Plus

    Both products have 15% minoxidil and topical finasteride at 0.1%.

great service as always
Have been ordering this product for more than 3 years. Seller always dispatched the product quickly. I was a little concermed right now as the covid-19 disrupts a lot of things. I am glad to receive it without any issue although it took a little longer.

Cannot recommend this company enough
In 2009 I became aware that my hair was thinning as shown in the before image. Later the same year I started using minoxidil 5 % from different suppliers. However, I was still looking for a better supplier, because propylene glycol irritates my scalp. So in 2013 i found MinoxidilMax and their products did the job, as my hair went thicker and fuller about 4 months after starting. I have tried a few of their products and have never had any issues with any delivery. I have been using their products ever since. Currently I am on the DualGen-15 NO PG, as I have found this one to be the most effective during my 6 years of experimenting with minoxidil. I cannot recommend this company enough - high quality for a great price.

It truly works
Dualgen 15 no PG has delivered great results for me. I started noticing new hair growth after about 2 months of use. The results are getting better and better. I highly recommend this product.

Faster results.
Dualgen 15 appears to work faster, causing new growth to appear quicker. I learned to apply it sparingly with the dropper in areas where most needed. My earlier use of a spray head was not good, in that it was noticeably tacky in the sprayed area for most of the day. The trick is to get it to the scalp area and not to saturate the overlying hair.

Put simply, it works
Am an old dude and I still have a relatively full head of hair thanks to this. Stops fallout dead in it's tracks. Wonderful product and absolutely no ill effects after many years of use. Dosage/concentration really does matter.

4 Months Progress
This is a great product for those with scalps sensitive to PG. It takes a little bit longer to dry but induces no irritation whatsoever to the scalp. You can see the progress in the before and after pictures; this is a top view with me looking forward as indicated by the glasses. Keep in mind my hair was longer in the before picture, yet the thinning was still much more visible. In both pictures the hair was combed diagonally to the left and back. Overall, the product is potent and has increased hair growth to the point that the diffuse thinning is not visible at all. With such progress in only a 4 month period, I am expecting an even further increase in hair density. I am very satisfied with the product and will keep buying it.

The ONLY solution that worked for me!
I've been using Dualgen 15 for 3 years now. I noticed hair growing in after only 2 months of use and after 6 months, my hair grew in thick and full. THIS is the real thing! As a woman, my hair is very important to me. Now I am able to keep it without wearing a wig or looking embarrassing. I am a registered nurse and have recommended it to my friends and family who suffer hair loss. It is safe and effective and gentle to the scalp. I'm so grateful this product is available to us!
