I’m taking both oral and topical finasteride

I’m confused about the effectiveness of taking both oral and topical finasteride simultaneously. Please give me some insight into this practice. 

I don’t see a point in taking oral and topical finasteride simultaneously. The oral form is better as it reaches the areas the topical form can’t reach. The topical also goes systemic, so your systemic dose may be much higher than oral. The use of topical liposomal finasteride is different than the standard topical finasteride as it is designed to stay mostly in the scalp.  This liposomal preparation is used when there are side effects from the systemic finasteride.
