It’s known that Propecia can regrow hair and if you stop taking it, you lose these hairs. But if you take Propecia for a long time, you’ll also prevent hair thinning and falling. So my question is, if you stop taking Propecia several years later, do you think you will lose all the new hair that have regrown and the hair you kept or you just loose the hair that came back after taking Propecia.
If you have taken Propecia (finasteride) for years and you’ve regrown some hair and prevented future hair loss, stopping it will result not only in the loss of the regrown hair, but may send your hair loss into overdrive.
In other words, you may start to lose the hair you were genetically programmed much more quickly than if you had just let it naturally progress. I’m not suggesting that you will wake up one day and you will have gone bald, but your hair loss may progress more quickly.
