To complement your Regaine solution, the most common and clinically proven oral tablet for male hair loss is finasteride. While the topical solution works by stimulating hair follicles to promote growth, oral finasteride works internally by blocking the hormone (DHT) responsible for shrinking hair follicles. Using them together often produces significantly better results. For women, other oral options like spironolactone might be considered depending on the underlying cause. Because these are prescription medications with potential side effects, it is highly recommended to consult your doctor or dermatologist. They will evaluate your health and prescribe the safest, most effective dosage for you.
