How should I prepare shampoo, hair products, and lifestyle records before my first hair loss consultation?

I am a 35-year-old woman concerned about hair loss. Before deciding on a treatment method, I would like to know what I should prepare for my first scalp consultation. Since I believe that hair loss requires an examination of lifestyle habits and scalp condition, I plan to organize materials that will be helpful for the consultation rather than simply counting the number of hairs I have lost.

Does the timing of when I wash my hair or whether I use hair products before the consultation affect the scalp observation? I am also wondering if I should inquire about the time gap between the consultation and any dyeing or perming I am planning. Regarding the shampoo and scalp products I normally use, I would like to know if simply writing down the names is sufficient, or if it would be helpful to prepare the ingredient lists and usage frequency as well.

Also, regarding medications, supplements, and dietary and sleep habits, for which period would it be most practical to organize the details? If necessary tests are required, I would like to know whether the same tests are performed on everyone or if the specific items are determined after a medical history interview and scalp examination. I am not trying to judge the condition based solely on the photos; this inquiry is intended to help identify the specific areas that need to be verified during the consultation, separate from the attached images.

Information regarding matters to check before the visit without arbitrarily stopping the product or medication, and any materials to prepare separately on the day of the consultation. I offer my thanks.
