Generally speaking, as long as there is no obvious intracranial hemorrhage and brain parenchymal injury after skull fracture, the prognosis is still very good. But many patients will have dizziness and headache for a long time after brain injury. This may be related to concussion.

I suggest that your friend try to rest for two months after being injured. If he has a headache or dizziness, he can take some sedative and brain tonic and compound gastrodia elata.

In addition, we must realize that skull fracture, who has no substantial intracranial injury, is actually not seriously injured, but many people think that skull fracture must be very serious, so under this psychological hint, there will be many subjective symptoms. If there are no obvious problems after treatment, don't carry too many bags and treat yourself as a complete person.
