How effective can I expect the hair loss treatment to be?

Lately, I feel like I am losing more hair than before after washing it, so I am looking into hair loss treatments. In particular, the crown of my head feels thinner than it used to be, and it bothers me even when taking photos. Since I haven't confirmed my exact condition yet, I plan to get a consultation to determine the cause rather than rushing into treatment.

While searching, I found various scalp care methods alongside hair loss treatments, and it seemed that the recommended approaches varied slightly from clinic to clinic. Therefore, I am most curious about the actual effectiveness of hair loss treatments. I am looking into whether noticeable changes occur in the short term or if consistent care is required, as well as the recommended frequency and treatment cycle.

Apart from hair loss, I am also taking care of my skin these days, so I am looking into skin treatments like Juvelook or Livy Heal. Since I am trying to manage both my facial skin and scalp concerns at the same time, I am worried that the cost might be higher than expected, so I am trying to prioritize. Livy Heal is frequently seen in the skincare field, and I am looking into Juvelook for its skin texture and elasticity; however, since the purpose is different from hair loss treatments, it is correct to consider them separately, right?

Rather than making a decision based solely on the expected results of the hair loss treatment, I think it is important to first check the current condition of your scalp and hair to determine if it is the right care for you. If anyone has undergone hair loss treatment, I am curious to know about the duration, cost, frequency, and satisfaction level. In particular, I would like to hear real-life experiences regarding what to check when starting the treatment.
