Kerafen Reviews:-Long-term use of Kerafen can help prevent the recurrence of toenail fungus and maintain healthy nails. South African users who continue the treatment after the initial infection is cleared often report sustained improvements in nail health. Regular application helps to protect against reinfection and supports ongoing nail strength and appearance. However, it is important to monitor the nails and adjust usage as needed. Consulting with a healthcare provider can provide guidance on the appropriate duration of use for individual cases. Long-term use, combined with good foot hygiene, enhances the likelihood of lasting results.
