How long should treatment last for different cases and stages?

The duration of use depends on the cause and stage of hair loss. In many cases, a minimum treatment period of about 3–6 months is recommended, as the effectiveness of the treatment can only be reliably assessed after this time. In cases of early-stage hair loss, improvements are often visible sooner. For more long-standing or severe forms of hair loss, longer-term or ongoing use may be advisable to stabilize the condition of the hair and slow further progression. Patience and consistent use are crucial.
