-Sirius starting to grow his hair out because he knows his mum will hate it
-Sirius asking Lily for tips on hair care and having a serious conversation over conditioners with her in the common room at 3am
-Sirius asking Lily to braid his hair so often that James get's angry and yells at him for "STEALING MY FUTURE WIFE AWAY FROM ME"
-Remus rolling his eyes at Sirius "obsession"
-Sirius making a scene because he has been attacked with Drooble's Best Blowing Gum by a bunch of Slytherins and now "It's all in my HAIR, Moony! HOW DO I GET IT OUT? DON'T TELL ME WE HAVE TO CUT IT?!" followed by a pretended faint.
Remus finally having enough because "I can't take this any longer, Prongs! We have to make him shut up or I'll be going to Azkaban for murder..." and sitting down with Sirius, a comb and his wand in his hands.
-Remus spending 3 hours on mission 'save the queen'until Sirius is happy again and accidently throws him off the bed because of an enthusiastic hug attempt
-Remus being rewarded at honeydukes with "As much chocolate as you can carry, my dear moony for you are my saviour, my hero, my..." "Shut up already..."
-Remus remembering how much it had calmed him down to brush Sirius hair on that dreadful day and making it a habit to do so before every full moon
Sirius allowing only Remus to touch his hair and finally putting a charm on it that gives everyone else a small electric shock because "Those damn girls won't stop touching it, Moony! THEY WON'T STOP TOUCHING IT! I need to protect myself from their filthy
hands!"
