As some of you may know, Ashton Kutcher revealed during a talk with Conan O’Brien that he’s taking Avodart, which basically is Dutasteride.
If you now compare his hair situation with the one of his un-identical twin brother, Michael Kutcher, it may be an indicator of Dutasteride working.
Of course they don’t have the exact same DNA but in my opinion this is none the less an okay reference. Also because we know he hasn’t done any hair transplant.
Of course, in the right person and the right time both finasteride or dutasteride may work for reversing hair loss.
