Why didn’t you put spironolactone directly into your minoxidil solutions, so it would have been more convenient to use?

When minoxidil and spironolactone are combined in the same solution, they will chemically react within a few days and degrade each other, causing a particularly offensive odor. Since this chemical reaction requires many hours to occur, the reaction does not occur if minoxidil and spironolactone are applied to the scalp one after the other from separate containers.

Better patient compliance. It's more convenient, since each topical dose only requires a single 1 mL application from one bottle. 5% Xandrox ® is odorless as compared to the offensive odor that can be associated with spironolactone. However, in terms of efficacy in treating MPB, topical minoxidil combined with either azelaic acid or spironolactone often yields the same results.

How much more effective are 5% Xandrox ® solutions as compared to using plain minoxidil solutions or the combination of minoxidil and spironolactone solutions?

Unfortunately, after almost two decades of use and evaluation, it is obvious that minoxidil solutions used alone have not been significantly effective for reversing MPB for the majority of patients. However, when minoxidil is combined with an inhibitor of 5-alpha reductase, the majority of patients will have positive visible results in growing scalp hair. The major problem with the use of topical 2% or 5% spironolactone is lack of compliance in its use rather than effectiveness. ...

If I’m using Xandrox ® or topical spironolactone, should I continue to take finasteride to lower the DHT level in the whole body?

Finasteride works systemically and will lower the serum level of DHT throughout the body. Xandrox ® works only where it is applied. If you are not having side effects from finasteride, it may be advantageous to continue taking finasteride to protect the hair on the scalp not yet affected by MPB, but is 'at risk. ' For patients with large areas of thinning hair, it may be advantageous to take finasteride in addition to using Xandrox ® 5% solution and/or topical spironolactone.
