There could be. Fanfiction is a vast world. However, it might not be a very common theme. But some authors who like to explore different aspects of characters might have written about Snape washing his hair. You can look for it in the relevant fandom sections of major fanfiction platforms.
It's inappropriate because it involves a very private and sensitive area. There are boundaries in personal and family relationships, and this topic crosses those boundaries in an uncomfortable way.
In this fanfiction, the scene of Carlisle washing Bella's wounds is significant as it likely serves to develop character relationships. It shows Carlisle as a protector and healer, which are important aspects of his character. For Bella, it might make her feel more connected to Carlisle and the world he represents. It could also foreshadow future events, perhaps if Bella's wounds are part of a larger threat or mystery in the story, Carlisle's act of washing them could be the starting point of their journey to uncover the truth.
Well, we could expect it to be quite character - driven. Since it's about Snape washing his hair, it might explore his thoughts during this mundane activity. It could also include some interactions with other characters, for example, if someone were to interrupt him while he's washing his hair. Or it might just be a humorous take on Snape's character in a rather unexpected situation.
Maybe the 'Firefly Comic' has a plot where a character in the comic washes something, and this action or the whole story in the comic is suitable for a daughter's bedtime story. It could be a very gentle and family - friendly comic with a simple yet engaging story.
We can make it about the growth of the daughter. When she takes on the responsibility of helping her mom, she is maturing and learning important values like compassion. This can be a positive story of a daughter's journey in becoming a more caring and responsible person within the family.
One way could be to read the comic aloud, emphasizing the pictures and the simple words. If there is a 'washes' part in the comic, you could make it more interactive by asking your daughter if she washes things before bed too.
Fairies were Ivan's fairy attribute evolution type and had extremely high defense. In order to evolve into a fairy, Ivan needed to learn the fairy skills, obtain two hearts, and obtain two hearts through the "friendship system" before leveling up. Fairies and Elves could evolve in Pokémon X/Y by capturing Ivan and using the Friendship System. The evolution process would take about 10 to 15 minutes.
