Catch-Up Period When Stopping Finasteride

Hi Dr Rassman,
Can you please explain the ‘catch up period’ scientifically when someone stop using proscar?
Kind regards

Propecia and Proscar (both Finasteride) block the effect of DHT on the impacted hair follicle. In simpler terms, it interferes with the ‘dying’ cycle for that particular hair. Each hair is programmed to live a particular number of hair cycles. It is believed that either the hair cycle is prolonged or another few hair cycles are obtained when the DHT is blocked. When the DHT is released from the blocking effect of Propecia, then it remembers where it should have been and goes directly to its genetic programming, whatever that destiny is. We see similar effects when we treat leukemia with one of the newer magic bullets. The same is true for Insulin and Diabetes, and Steroids for Addison’s Disease (John Kennedy had it). Provided that the patient stays on the drug, the disease is blocked from taking its normal course. If the medication is stopped, or the drug is not maintained at its recommended dose, these diseases may take the life of the person, or by maintaining the drug they may hold off the effects of the disease indefinitely. Propecia may hold the hair in a more healthy state for long periods (each person varies with the power of the inherited genetic profile found in that particular individual). As we are each different with different genetics, some people will have a long, more effective course with blocking DHT than others. The good news is that we are not talking life or death here, just hary or balding.
