I would like to inquire about hair loss treatment.

Lately, I have been noticeably losing a lot of hair and my hair has become thinner, so I am very worried. It seems like home care has its limits, so I am seriously considering getting professional hair loss treatments. Since this is my first time, I have some questions regarding the treatment frequency. I am wondering how often it is generally best to receive treatments consistently.

Also, would combining home care with hair loss treatment create a synergistic effect? ​​I would be very grateful if those who have undergone hair loss treatment could share their firsthand experiences and precautions. I would also appreciate it if you could let me know in the comments where you usually received the treatment!
