To update a cache you can use such. event function in your User model:

protected static function boot()
{
    parent::boot();

    $removeCacheFunc = function ($model) {
        $key = self::USER_CACHE_KEY . $model->id;  //compile cache key in your way
        \Cache::delete($key);
    };
    static::saved($removeCacheFunc);
    static::deleting($removeCacheFunc);
}

Next time you call Cache::rememberForever() will not find this entity by key and will make it on the fly
