How do I check the preparation and intervals for each area before a laser hair removal consultation?

I would like to receive a consultation regarding hair removal. Since hair thickness, skin tone, and irritation levels vary by body part, I am curious about the criteria you prioritize during the consultation. I would also like to know if treatment plans or recommended intervals differ for curved areas like the face and neck compared to larger areas like the arms and legs. Instead of rushing to make a decision, would it be better to just have the consultation first and receive specific details regarding the estimated number of sessions, intervals between sessions, cost range, when to shave before the procedure, aftercare to avoid on the day of treatment, and post-treatment precautions such as moisturizing and sun protection? I am also curious how dates are adjusted if I have outdoor activities or scheduled commitments. If my skin is sensitive, I would like to know how the possibility of irritation or redness is explained for specific areas, and under what conditions I should postpone the appointment or consult with medical staff first. I would like to carefully confirm the appropriate range and interval for my individual condition during the consultation.
