Developed alopecia aerate after FUE near donor area. Dermatologist says apply Provate S lotion at night. Advice? (photos)

After 10 days of FUE hair transplant, i started developing small alopecia aerate (hair fall) near donor area. What should i do?. My dermatologist says after looking at my pics that I should just apply Provate S lotion at night only. Will this portion of alopecia aerate have hairs again or will it spread more?. Whats treatment in general or precautions are recommended.
