So it's been about 5-6 months since we decided on 'locking' Pipo's hair. Every week or so I have been retwisting, but it has been fuzzy and loose, and sometimes discouraging to me, as I have put so much time into it. But I can finally say it is looking fully locked. If I let it go a little longer, it's staying pretty tight. I am obnoxiously proud every time someone asks who does his hair, and he points to me!
