A woman works in the field of hair treatment using a device that captures images of the scalp to identify the cause of the problem and treat it. As part of her job, she takes a small localized image of the scalp and explains the cause of the problem in a simple way. She then shares this image on her WhatsApp status as a form of promotion for the treatment and its importance. Of course, the image is localized and small, only showing the scalp without capturing the patient's face or the shape and size of her hair, just a localized segment. Is there any sin or prohibition in this?
