My SiL kept up her colouring routine all through her pregnancy and niece is fine. I know there's no way I am going to have time for a proper "pamper" hair-cut post-Liebling, so I really made the most of the one I had done in July! (Sadly, although I had 3-4" off it has almost all grown back now so I'll "need" another one soon; bet it won't be until Jan now though!)
