Sounds kinda creepy...I would be mortified if my therapist tried to cuddle with me and play with my hair. Just the fact that you are questioning boundary issues should put up a red flag. With that said, I have a strong belief that therapists should not hug their patients. I have seen a lot of posts on that but it seems that by the therapist giving in to you and hugging or "cuddling" you, they are taking the easy road. Therapy should be about developing coping skills and correcting self deductive habits, etc. A therapist that hugs their patients is essentially robbing them of the motivation to seek this in the "real world" because the therapy room is "safer" ( I am user this word lightly) It seems this would make you more reliant on them. They should be working with you to determine why you desire hugs from them ( someone, whom, if you think about it, you probably don't know much about. ) so they can help get to the root of the issue.
