However, it could also cause some friction. The more traditional wizards and witches might view his long hair as unkempt and disrespectful of wizarding traditions. This could lead to some older characters looking down on Harry or being less inclined to trust him.
In his romantic relationships, his long hair could be either a plus or a minus. A girl who likes his wild and free - spirited side might be attracted to it. But someone who prefers a more polished look might be put off. It all depends on the individual's taste and how they view Harry's overall character.
Some might find it charming. For example, his friends like Ron and Hermione might see it as just another part of Harry's unique personality. It could make him seem more approachable to those who are drawn to his non - conformist ways.
Maybe it's a magical protection. In the wizarding world, there could be some ancient magic associated with hair length. Long hair might act as a sort of shield or a connection to some deeper magic that Harry unknowingly benefits from.
If Harry is sleepwalking, it might worry his friends. For example, Hermione would probably be very concerned and try to find a way to stop it. This could strengthen their friendship as she devotes time to helping him. Ron, on the other hand, might initially find it funny but then also realize the seriousness. It could also make some of his classmates more curious about him, which could either bring them closer or create some distance depending on how they react to his sleepwalking episodes.
His friends might be initially shocked but then find it hilarious. Ron would probably tease him good - naturedly. Hermione, on the other hand, would be more concerned about how to reverse it at first but then accept it as part of Harry's new look. Some of his Slytherin rivals might use it as an excuse to taunt him more, thinking he looks ridiculous.
It might make his relationships more interesting. If he reads fanfiction that has unique takes on his friendships, like a story that shows a deeper bond between him and Hermione, he could be more conscious of those relationships in real life and try to strengthen them further.
His relationship with Hermione might change as she becomes overly worried about the cause of his silver hair and starts researching every possible magical explanation. She might be constantly fussing over him, which could initially annoy Harry but then he realizes it's her way of showing care.
In some fanfics, his long red hair might make him more attractive to certain characters. For example, Sakura could start seeing him in a new light, as the change in his appearance makes him stand out more. It could also make his enemies more cautious, thinking he has some new power associated with the hair.
He could use a simple spell like 'Capillus Ordinatus' to make his hair neatly combed. It's a made - up spell for this purpose.
The transformation of Harry Potter into a werewolf in the fanfiction could have a huge effect on his relationships. His enemies might use it against him, and his allies might have to work harder to protect him. Also, it could change how he sees himself and how he interacts with the magical world as a whole.
His jealousy might make him a bit withdrawn from Bill. He could be less friendly and more distant, which could cause some tension between them. As for his relationship with Fleur, he might act a bit awkward around her, not really knowing how to handle his feelings.
Socially, it would be a huge change. Some people might be scared of him, thinking he's some kind of monster. But his true friends would still stand by him. He might have to deal with a lot of stares and whispers wherever he goes in Hogwarts. Also, he'd probably have to come up with explanations for new students or visitors who see his snake - hair for the first time.
