Regrowth
What all hair loss treatments have in common is that they lower the standard of what regrowth means in order pass their treatment as a success.
All modern hair regrowth treatments are superficial and deal with surface level problems. The root problem must be targeted in order to have a real regrowth. The underlying problem is that the hair follicle is either dying or already dead as a result of hormones. Doctors can’t regrow dead hair follicles so they turn their attention towards prolonging a dying hair follicle. Your hair is forced into a growth phase by drugs or other methods such as micro needling. These superficial methods consume time, effort, and money. The Worst part is they cause side effects. In the end patients give in to baldness because it's not worth the fight.
