I would like to know why this Mintop minoxidil 5% solution is not working like Tugain 5% solution from doctor on my head?

While minoxidil works fine for the select few, the problem with the
medicine is that it does not actually stop hair loss. Instead, DHT will
continue is binding to the hair shaft which will eventually overtake any
additional growth caused by the Minoxidil and die, perhaps just
slightly later than it would have without the medicine.
Also, the alcohol base required to support the active ingredients
also cause irritation of the scalp and severe reactions for many people,
such as the increased shedding you are describing. The fact is that it
does not work for everyone, and even if it does, not for long and not
without side effects.
Any medicine that actually can make changes
inside your body, are  required under the FDA to be available by
prescription only. This therefore means that it is not possible for
anything that does not require a prescription to cure or prevent hair
loss or regrow thinning hair. Thus, a personalized medicine will be the
best choice because instead of a "one size fits all" approach, you will
be taking something
which is truly catered to your body's needs.
The treatment is out there. Good luck on your search.While minoxidil works fine for the select few, the problem with the
