It is not necessary to take Finasteride for a long period of time after hair transplantation. Usually you need to take it for about 2-3 weeks to stop it reasonably under the guidance of your doctor. Finasteride is a specific inhibitor, mainly used as androgen antagonism, can be used for androgenetic alopecia. Usually after hair transplantation, the use of Finasteride helps to regulate the hormone level in the body, and also helps to improve the survival rate of hair follicles after hair transplantation, so after hair transplantation, the doctor usually orders to take Finasteride for 2-3 weeks to consolidate the treatment. After hair transplantation, due to the growth cycle of the newly implanted hair, it has not yet established a good blood relationship with the scalp, so there will be a period of alopecia areata, the hair will continue to fall out, which is a normal phenomenon, if the amount of hair loss is relatively small, the body’s hormone level is relatively normal, you can do not eat finasteride, if the amount of hair loss is large, the body’s hormone level is abnormal, then you need to take finasteride orally to improve the symptoms. Considering the different sensitivity of people to the drug will lead to a large difference in the time of use, and the drug will have damage to liver function, so it is not recommended to take for a long time. Usually, when the transplanted hair follicles grow stably and the hormone level in the body stabilizes, the medication can be reasonably stopped under the guidance of the doctor.
