I am curious about the effects of hair loss treatments like scalp mesotherapy.

Hello. I am in my 30s and very worried that my receding hairline seems to be getting wider. I have considered oral medication, but due to concerns about side effects, I am considering hair loss treatments at a clinic first. I have heard that there are injection treatments that directly supply nutrients to the scalp. I am wondering if these treatments actually provide substantial help in strengthening hair roots and slowing down the progression of hair loss. I am also concerned about whether it will interfere with returning to daily life immediately after the procedure, and whether bruising or swelling will last a long time. Although it varies from person to person, could you please tell me how long it typically takes to see visible improvement after a hair loss treatment? Providing a rough estimate of the cost would also be very helpful for scheduling an appointment.
