Do I still need to take medicine after hair transplantation?
After undergoing a hair transplant, many friends often ask: "Is the procedure a one-time fix? Do I still need to take medication?"
In reality, while hair transplantation can restore sparse areas, failing to control the root cause of hair loss will cause your native hair to continue shedding. This can result in uneven hair density and compromise the final outcome.
Among these, oral medication Finasteride plays a pivotal role in maintaining hair volume and stabilizing results post-surgery.
The main cause of male pattern hair loss is high DHT (dihydrotestosterone) in the body.
- DHT causes hair follicles to gradually atrophy
- The hair becomes finer and shorter
- Eventually causing the hair follicles to stop growing
The mechanism of action of Finasteride:
- Inhibits 5α-reductase
- Lowers DHT concentration in the body
- Slows down or even stops hair loss
Therefore, hair transplantation is responsible for "replenishing hair volume," while medication is responsible for "preserving native hair," and the two are inseparable.

Q1：What happens if I don't take medication after hair transplant?+
Native hair will continue to fall out, potentially leading to uneven hair density and affecting the overall appearance.
Q2：Does Finasteride need to be taken for a lifetime?+
Not necessarily; it is usually recommended for at least 1–2 years, with dosage or duration adjusted later based on the progression of hair loss and evaluation by a doctor.
Q3：Is the incidence rate of side effects high?+
Approximately 1%–2%, and most side effects resolve after discontinuing the medication, so there is no need to worry excessively.
