The Difference Between Formula ZFIN or Finasteride and Formula ZMIN or Minoxidil

There are many approaches to treating hair loss and receding hairlines, and at Ziering Medical our team of hair restoration experts have a vast toolkit that extends beyond surgical procedures and transplants. This is especially applicable to those whose hair loss levels have not reached a point where hair transplants are warranted. And this is why we stress the importance of early diagnosis and getting consultations before one’s hairline has receded significantly. In these cases, there are a variety of non-invasive hair restoration treatments that can prevent further balding, including medications such as our finasteride-based formula ZFIN and minoxidil-based formula ZMIN solutions.

Differentiating Finasteride and Minoxidil

As their names suggest, formula ZFIN utilizes finasteride while formula ZMIN uses minoxidil. For those unfamiliar with these substances, it is easy to confuse the two. The difference between finasteride and minoxidil is that finasteride prevents hair loss by stopping the body from converting testosterone into dihydrotestosterone or DHT. This is a sex hormone that causes the miniaturization of hair follicles. One of the side-effects of finasteride is the risk of teratogenicity in male fetuses. This means finasteride is contraindicated in women of childbearing age.

On the other hand, minoxidil is a vasodilator that when applied to the scalp causes the blood vessels to widen, thus increasing the blood flow to hair follicles and synchronizing the hair to be in an active growing phase. This may cause some shedding in the first couple of weeks.  Don’t be alarmed, because after this period of hair shedding, patients experience hair regrowth with fuller, thicker and stronger hair.

Formula ZFIN

Finasteride or Propecia, as it is more commonly known, is the go-to FDA approved medication for hair loss patients seeking to slow down hair loss and regrow hair. It has a proven track record of efficacy and delivering results; however, many patients have concerns regarding finasteride’s side effects and opt for topical finasteride rather than the oral tablets. 

Formula ZFIN is a topical finasteride solution that requires prescription. It is composed of 0.25% finasteride, 0.01% fluocinolone and 0.05% retinoic acid. Ziering Medical devised formula ZFIN after research and tests on patients to determine safety and efficacy. ZFIN is a unique finasteride compound that is applied to your scalp daily, providing the needed DHT-reducing effect of finasteride to improve hair growth and reduce hair shedding while ensuring the medication works only locally. ZFIN may be appropriate for men and in some cases, postmenopausal women.

Many of our patients have reported satisfaction with the early results from ZFIN. Particularly because they do not have to experience the side effects of taking oral finasteride tablets. At Ziering Medical, we recommend combining ZFIN with ZMIN and even laser therapy for added effect. 

Formula ZMIN

Minoxidil is another popular and effective treatment option for pattern baldness and is likewise FDA-approved. Additionally, its effects can become further optimized and longer lasting when combined with other substances and therapies. 

Ziering Medical’s formula ZMIN is a customized and compounded prescription solution that contains the FDA-approved hair growth medication Minoxidil. As well as retinoic acid for improved penetration and a complex blend of anti-inflammatory, antioxidant and anti-androgen ingredients. 

With ZMIN patients can get a more powerful, user-friendly solution for stimulating hair growth and decreasing hair loss in men and women. 

Formula ZMIN requires a prescription so if you are interested in this treatment, reach out to Ziering Medical to schedule a consultation.


One-on-one consultations at Ziering Medical are the best way to determine whether you require a prescription of either ZFIN or ZMIN, or perhaps a combined treatment plan. Routine medical tracking is also recommended in order to achieve the best possible results with any hair restoration regimen and monitor the progress of the treatment.
