Does dutasteride stop hair loss forever?

Although blocking DHT almost completely, is, theouitically, able to prevent hair loss for a very long time, there is also a genetic component in which the number of hair cycles of hairs within the balding pattern distribution is also subject to limitations. For example, if a specific young man is genetically going to develop a Class 3 pattern of balding, then if it he gentically programmed for 7 hair cycles of three years each on the life of these hairs, and these hair then die at the end of the 7 hair cycles (all at the exact same time for the purpose of this model), dutasateride can only prolong the hair cycles, not the number of hair cycles. So a simple math formulae would predict 7 hair cycles of 3 years each developing a Class 3 pattern of balding would appear immediately at 21 years of age (3 times 7). IF the cycles were prolonged to 4 years because of the drug (theoritically you start dutasteride when you are born for this calculation to work), then 7 cycles multipled by 4 years each, get you to an age of 28 before you develop that Class 3 pattern, all at once for this model. One morning you wake up, and in the shower your hair falls out and you develop an instant Class 3 pattern because your vulnerable hairs are at their life. those hairs within the Class 3 pattern. Of course, the hair cycle length varies by age and sex thoughout the formative years and within the pattern of balding, the hairs vary with their life expectancy. So simple calculations like those above make no sense, but it does show the complexity of making sense out of predicing hair loss with drugs like finasteride and/or dutasteride.
