There are not a few people who suffer from hair loss in their youth. “Previously, most of the patients attending the clinic were over 30 years old, but now, even young people who have just left puberty are starting to have hair loss problems.” Patients aged 20-30 years old can account for more than 50 percent of all patients seen. More than 90% of baldness is androgenetic alopecia, commonly known as seborrheic alopecia. There was no treatment for this disease in the past, but now there is a way to treat it. Those who suffer from hair loss should not avoid treatment, but should go to a regular hospital to receive professional diagnosis and treatment in time to avoid further aggravation of the hair loss condition and irreversible changes. Generally speaking, the earlier androgenetic alopecia is treated, the more effective it is. The medication is very simple, one tablet of finasteride can be taken orally every day, and the effect can be seen in 3-6 months in general, and individuals need more than half a year to see the effect, and the best effect can be achieved in 1-2 years of medication. Therefore, the treatment of androgenetic alopecia is one is to “early”, one is to “insist”, patients should have a long-term battle psychological preparation, not because of slow results and give up treatment.
