When you're going away on holidays, packing is always such an issue. You need to pack enough for days or even weeks but you also need extra room for the amazing things that you'll buy.
I can usually pack my make up quite easily as I like to reach for multi-purpose products. Clothes are always a difficult decision as you need to be practical as well as a fun.
I find that haircare is easy. You don't really need a lot of products to be able to create some lovely (and practical) hair styles.
