The last few days I've noticed that my toddler's hair has a musty smell when it's wet. It doesn't smell at all (in fact it smells lovely) when it's dry. This is the same if she's damp due to sweating or even after just having had her hair washed, although I'd say it's milder when washed maybe due to there being a shampoo scent too.
There's no sign of any flaking/cradle cap or any rash or irritation on her scalp.
Any ideas? Could this just be because her scalp has been damp more than often lately due to the weather? She has mid thickness (not v thick) curly hair but loose curls not very tight ringlets (Caucasian hair)
