TO CLARIFY --
The dots, lines, lint or hair marks can come from three different sources, two of which you have control over, one of which the lab mainly has control over:
1) Your scanner could have dust in it or on surfaces that make spots on the scans. Remedy: make sure the scanner is clean before scanning.
2) The negatives could have gotten dust and lint on them between the time the lab dried them and when you scanned them (could be their fault and your fault). Remedy, carefully clean any loose dust or lint from each negative before scanning, using a air puffer (like you'd used to clean dust off of a lens) and/or a very soft, clean brush.
NOTE: It would be a good idea to check and possibly clean the scanner and dust the negatives and do a rescan, in order to see if your scans still have marks on them, before considering the next issue.
3) The negatives were not washed sufficiently by the lab and dried with chemical residue on them and/or they were dried where dust could get on them while they were still wet, meaning it is stuck onto the negatives. Remedy: First, show the lab how dirty the negs they gave you are, and ask if they can do better next time. They might offer to rewash these negs and keep them clean. If you aren't satisfied with their answer, you can wash and dry the negs yourself in order to get any chemical residue and stuck on dirt off of them and trying to keep them as dust free as possible before scanning.
ALSO --
1) I really like the portrait. Nice job!
2) I expect negatives to get dust and lint on them even when handled with care. Looking carefully at them just before scanning or inserting them into an enlarger, and usually having to blow off some additional dust at the last minute is normal and to be expected.
3) Years ago, I remember having to ALWAYS remind the clerk at the photo store where I got film developed, to mark "clean neg" or "clean slide" on my order if I was ordering a reprint or an enlargement. If I didn't have them do that, half of the time the print would have a dust or lint mark on it, and they would have to redo the job for me.
