✔ The Ultimate Hair Regrowth Solution: DualGen-15 With PG Plus is the most powerful solution available for fighting against hair loss. Compared to Dualgen-15 With PG, this product has additional topical finasteride.
✔ Two FDA Approved Ingredients in One Solution: DualGen-15 With PG Plus has the maximum strength of FDA approved hair growth stimulator (15% minoxidil) and DHT blocker Finasteride (0.1%) with other auxiliary ingredients such as Azelaic acid (5%), Retinol (0.25) and Caffeine.
✔ No Need to Take Finasteride Pill: If you are currently taking 1mg finasteride pill a day, you don't need to continue to take the pill if you use this topical solution. The amount of finasteride in each mL is 1 mg.
✔ Who Should Use DualGen-15 With PG Plus: This product is intended for men with advanced hair loss. It is most suitable for those who used Dualgen-15 With PG for at least four (4) months without satisfactory results.
✔ Propylene Glycol (PG or PPG): This product has PG. If you are known to be allergic to propylene glycol, it is recommended to use Dualgen-15 NO PG Plus, which has the same effective ingredients as this product but without PG.
Perform a “use test” to ensure you are not allergic to the product by applying a few drops of DualGen-15 With PG Plus to the triangular cavity of the elbow joint. Do not use this product if redness or inflammation of the spot occurs.
Using the included dropper, apply up to 1 ml of DualGen-15 With PG Plus to your scalp in the hair loss area in the evening. Once a day should be sufficient for most people. It can be used in conjunction with lower strength solution such as our EssenGen-6 Plus, DualGen-5，or Essengen-5, in which case use low strength product in the morning and DualGen-15 With PG Plus in the evening; using each product once daily.
If you do want to use this product twice daily, please do it only after it is proved that once a day is not effective enough and you have no side effects to use it twice a day.
Use no more than 1 ml each time. You only need to use enough to cover your balding/thinning area with a thin film of the solution. No massage is needed. You can use your finger tip or the tip of the dropper (included) to spread the solution. Try your best to apply the solution directly to your scalp by parting your hair. Otherwise you end up with wasting the product on your hair and it takes long time to dry.
Dr. Richard Lee made a cocktail with minoxidil and finasteride in it 10 years ago. According to his clinic experience, it works a lot better than minoxidil alone at the same strength. The results are similar or even better than using the same strength of minoxidil together with oral finasteride pill (1mg) while with less side effects.
In the 7th World Congress on Hair Research, a Dutch research group reported the effect of topical and oral administration of finasteride on DHT levels in scalp and serum. The results are shown in the Table below. It shows that when 1 mg of topical finasteride (once a day) controls DHT level in scalp more effectively than 1 ml of oral finasteride. It reduces DHT level in scalp by 71% while the oral finasteride only decreases by 51%. Meanwhile, both administrations decrease DHT level in serum by almost the same degree (~70%). This is understandable, as the topical finasteride is applied to scalp directly and finasteride concentration in scalp is expected to be higher than when the same amount of finasteride is administrated orally. This study also suggests if you get side effect from oral finasteride, you will most likely get side effect from topical finasteride.

There are some other studies that show similar conclusion. In 2012, a Thailand group compared the efficacy and safety of the 24 weeks application of 3% minoxidil lotion (MNX) versus combined 3% minoxidil and 0.1% finasteride lotion (MFX) in men with AGA. Results show the MFX group had significantly greater improvement in than the MNX group in the hair regrowth, and no side effect was reported (see the details of this study below, study 2).
In 2009, an Iran group compared the therapeutic effects of topical finasteride gel and tablet in treatment of the male pattern hair loss, and found that therapeutic effects of both finasteride gel and finasteride tablet were relatively similar to each other ( (see the details of this study below, study 3).
Interestingly, the results also shows that when you applied 0.5 mg topical finasteride twice a day (total amount is 1mg) is actually less effective in controlling DHT level in scalp, compared to applying 1mg of topical finasteride once a day. The former decrease the DHT level in scalp by 47%, while the latter by 71%.

A new proprietary topical formulation, P-3074, containing finasteride 0.25% as active ingredient and hydroxypropyl-chitosan (HPCH) as film-forming agent, was developed for androgenetic alopecia. The present study was aimed at investigating the pharmacodynamic profile of finasteride in terms of dihydrotestosterone (DHT) concentrations in the scalp and in serum after multiple topical application of P-3074 or oral finasteride intake in subjects with androgenetic alopecia. Eighteen healthy men were randomly allocated to P-3074 or oral treatment after providing written informed consent. Twelve volunteers applied P-3074 topical solution for 7 days: six subjects once daily (o.d.) in the morning and the others twice daily (b.i.d.) in the morning and in the evening. The third group of six volunteers was administered 1 mg oral finasteride once daily in the morning for 1 week. Scalp (vertex) biopsies were collected at baseline and 6 hours after last dose administration, while serum samples were collected at baseline, before last administration, and 6 and 12 hours after the last multiple dose. A marked decrease in scalp DHT levels was observed: by 47.22% with P-3074 b.i.d., from 1.91 (±0.54) to 1.01 ng ml−1 (±0.39), by 71.20% with P-3074 o.d., from 1.52 (±0.41) to 0.44 ng ml−1 (±0.08), and by 51.11% with the oral formulation, from 1.39 (±0.25) to 0.68 ng ml−1 (±0.34). Serum DHT was reduced by 69.3–74.0% with P-3074 b.i.d., 67.6–80.4% with P-3074 o.d., and 69.7–76.1%with the oral formulation. These results showed a similar inhibition of serum DHT after 1 week of finasteride administration with the three dose regimens and were consistent with the results obtained in a previous P-3074 PK study. These findings show that DHT concentration in the scalp, after 7-day treatment course of P-3074 o.d., was more reduced (about 40%) than after 1 mg oral finasteride administration for the same treatment period.
Please be advised that there are two versions of Dualgen-15 Plus: one is DualGen-15 NO PG Plus, the other is DualGen-15 With PG Plus.
