How can I effectively prevent and manage finger calluses while playing the guitar?

To prevent and manage finger calluses while playing the guitar, you can start by gradually building up calluses through regular practice. Use proper technique and finger placement to reduce friction on the strings. Keep your guitar strings clean and change them regularly to prevent excessive wear on your fingers. Moisturize your hands to keep the skin soft and supple. If calluses become painful, consider using protective tape or gloves while playing.
