The syllable stresses are at exactly the right places, making this haiku absolutely lovely when you read it out. That's exactly what haikus should achieve, because they aren't really the thing when it comes to deep, meaningful themes, since they're so short. The last line was, though simple, my favourite. Well done!

I really like it. Simple, beautiful and meaningful haiku =)

I enjoyed how you personified your hair. This haiku carries a great technique, thank you.
