Some customers have decided to switch days they use each product (one day HAIRMETTO, one day minoxidil) with the intent of gradually phasing out minoxidil days. Of course if you have any adverse reactions using this approach please discontinue use or consult a physician. For realistic expectations, please know you may experience shedding again. Regarding shedding, its not the particular product so much as it is the disruption in the hair growth cycle in changing products. Minoxidil is not blocking DHT. The ingredients in HAIRMETTO do.  According to the Mayo clinic: “ People typically lose about 100 hairs a day. This usually doesn't cause noticeable thinning of scalp hair because new hair is growing in at the same time. Hair loss occurs when this cycle of hair growth and shedding is disrupted...” Potential Symptoms When, for the first time you are using a product that blocks DHT, this may cause a disruption in the cycle of hair growth in some individuals. However, it also means hair is responding to the treatment. Even though minoxidil doesn't block DHT, it lengthens the hair growth stage thus disrupting the hair growth cycle. Notice what the Mayo clinic mentions about those who start Minoxidil for the first time: “ At first it may cause you to shed hair. New hair may be shorter and thinner than previous hair. At least six months of treatment is required to prevent further hair loss and to start hair regrowth. You need to keep applying the medication to retain benefits.” Whether you are switching onto minoxidil or off it and on to another, it stands to reason that there will be a disruption in your normal hair growth pattern. But keep in mind that for a truly effective treatment, you need to block DHT which is choking the roots and thinning the hair. So while you may shed some already weakened and thin hair, further hair loss will be halted due to DHT being blocked - without drug related side effects.
