Young men rarely get Telogen effluviums. When it does happen, it goes away by itself. If it does not go away, it is likely early genetic hair loss. If it is early genetic balding, it will not reverse. You might want to see a doctor and get a HAIRCHECK test for a good baseline measurement to compare with future measurements so that you know what is happening with your balding pattern.
