    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 solution 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 of people who switched from regular 5% minoxidil to Dualgen-15 do NOT experience minoxidil shedding. About 16% 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 (15.0% 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 slows down slightly 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 from 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. How do I know if your product has the amount of minoxidil you claim?

    A. Very good question. You should ask the question when you shop high strength minoxidil online. We have our product tested by an independent reputable USA lab to ensure that the concentration meets our specification.

    You can see the testing result at the end of this page. The testing result confirms that the minoxidil concentration of our product is right at the target.


    7. 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 the minoxidil is number one hair regrowth product around the world. It is available without prescritpion 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.


    8. 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. 


    9. 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.


    10. 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).


    11. Why is azelaic acid added to 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.


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

     A: The stability of 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 crystal is 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.


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

     A: we have many such photos sbumitted by customers. 

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

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

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

    15% minoxidil results


    14. 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%.



  • best 15% minoxidil







  • (1). If you are not allergic to propylene glycol, you can choose our DualGen-15 With PG that is expected to be slightly less greasy than DualGen-15 NO PG.

    (2). This product is recommended to use once a day. You can use it with a lower strength of minoxidil product such as Dualgen-5 or Essengen. Using DualGen-15 NO PG in the evening is recommended because it takes slightly longer time to dry than a 5% minoxidil solution (such as DualGen-5 or EsseGen-5) because of the high concentration of minoxidil and the additional effective ingredients. 

    (3). If you want a product with stronger DHT blocking capability, you can try Dualgen-15 NO PG Plus or Dualgen-15 With PG Plus.

Dual gen 15 no pg
This is a great product... Occassionaly they may offer Plus with Finasteride. No PG means no drying alcohol. No propolyne glycol. Minoxidil causes excess hairs ( hirutism) in 99 % of users. So probably if your not getting desired results the concentration is too low. This product lasts a long time..
Really works
This product is great and really works.
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.
Early results
I knew it would take at least 3 months to get decent results. And its been only 1 month so far. I am getting some new hair growth but its hard to see because my hair is mostly grey. At the recommendation of a successful user I am using it twice daily instead of once. He reports that the results are much better when used twice daily. In addition, since minoxidil works primarily by increasing circulation, I have also added 3 minutes of scalp massage immediately after using the product. This consists of a two handed rhythmical firm tapping with all my fingers all over my scalp. The real prelim though will be after 3 months and especially after 6 months. After all even after hair transplant, the full benefit isn’t seen until about 6 months.
I am in my 60's, and had a large area which was almost completely bald, only a few hairs in it. Now unless you get up close, it looks like I have a full head of hair. A bit thin, but enough to cover. Very pleased.
good product
fast delivery and a quality product

Dualgen 15% No PG
I am very impressed with this product I myself started to see results in as little as 30 days.
Entrega en España a los ocho días del pedido, buen precio. Lo aplico directamente al cuero cabelludo, produciéndose el secado en muy poco tiempo, con molestias muy suaves, siento unos pinchazos flojos por ambos párpados durante unos minutos después del uso, debe ser por ir al 15% y ser más efectivo. No experimento en el cabello la sensación de quedar pegado ni aceitoso y picazones como otros minoxidiles. Lo llevo usando menos de un mes, y la puntuación es muy buena, y las sesiones las realizo rápidamente, con otras marcas me lleva más tiempo.
Fabulous results
Reasonably priced product, great results seen within 3 months. It does take a while to dry but my son used the solution with PG and got scalp irritation.
The delivery time to Hungary's excellent...
- Ordering such products regularly - Arriving before my expectation, i.e. within 1week, excellent
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.
4.5 *
Geat results just takes time to dry.
Great trader. Product arrives super quick. Early days yet, but given the exceptional reviews I'm hoping for some good results.
Good, more potent/greater results than others
I am not a chemist. However, my opinion would be that the additional ingredients, Retinol, Caffeine, and ABN Complex are responsible for the better results of this product. I believe the mixture of the third additional ingredient cannot be published. Bottle states "TM". It would be helpful for the manufacturer to give a brief description of what the third ingredient's benefit is/are and why. Enough detail can be provided as to be helpful to us, the customer, without infringing on your privacy concerns.
Great product. Very fair price, great quality with labels that can be trusted. Rest assured when you purchase here.
very promising product. Using only for 3 weeks.
Got this last 3 weeks ago and started using. It's too early to conclude but it think my hair is showing signs of growth. I will continue using this for few months.
MonoxidilMax - cheap and effective alternative!
Yes! This product is cheaper than other similar products and is of high quality. 5 stars
6 years of buying from this seller
I’ve bought Dualgen and minoxidil etc from this seller since 2012. I have never once had a problem, or undelivered product, or items seized by customs. Just amazing, solid, reliable service for 16 years. I used Dualgen as a prophylactic measure when I had no hair loss whatsoever. My hair has gone slightly thinner over the years (I’m 60 next birthday) but my hairdresser, a trichologist, told me that I’d have huge hair loss by now if it weren’t for minoxidilmax.
Fast shipping, i'm looking fw. to see result
Amazing product!
Great results and excellent company!
great product
very quick from order to delivery. I use it with other products but after years of looking for something that works I do think I have finally found the right combination and I am now seeing growth.
Great producd
Will definitely deal with again. Fast shipping and Great producd
Works better than 5% Minoxidil
It definitely works better the lower concentration ones, I have been using minoxidil %5 for years it always works for me until recently it seems to stop working. Now I got the higher concentration and I back to track, my only complaint about it is it does not work that much faster, and it drys out you hair and scalp
can't be any happier
I'm a 45 year old man, I"ve been off of Propecia for over a year and started using DualGen 15 (DualGen 5 in the mornings) recently. Now a little over 2 months later there a large crop of smaller hairs coming in, almost like I have a second canopy-if you know what I mean. Also have noticeable growth on the front hairline. Very satisfied customer
Love it
Will definitely deal with again. Quick response. Fast shipping. Great product, exactly as described. A+++, Smooth transaction.
Way better than Rogaine
Had used Rogaine for 3 years prior to this. I didn't see any regrowth but had severe scalp irritation with Rogaine. I have zero irritation with this product and hair regrowth is very obvious after using it for half a year.
