Dds scalp is really wiffy. It smells slightly sour or as my 5 year old niece puts it 'of poo'! She's 2.5 months and has smelt really since she was born. I bathe her every other day so she's clean. She has eczema in her hair and i've done a brief web search which suggested the two things may be linked. Has anyway else had experience of this? Really want to solve it.
