My Dermatologist Prescribed Olux Foam for Hair Loss Prevention

My dermatologist recently prescribed me olux foam to apply to my scalp to help prevent mpb, not really sure what it does or why he prescribed it, any ideas? thank you in advance

Olux Foam is a topical corticosteroid. As such, it has no value for the prevention of male patterned genetic hair loss. The chronic use of any steroid is bad for you. It does get absorbed by the body and if you take it over prolonged periods of time it might suppress adrenal function. Steroids are known to cause hair loss, although the dose of skin application may not be enough for that complication. This drug is used mostly for psoriasis. Are you sure that this is not what your doctor is treating?
