Hi
what works for us is to use a wet sponge with plain warm water to gently wash her head and hair - some people might find this a little weird but our 10 mth old has never had her hair shampooed, just washed in this way. She has always had a lot of hair too, and it is silky and lovely so not suffering through lack of shampoo - it really isn't very natural to use detergent in hair, ask any trichologist and especially babies' hair, apart from the odd bit of food smeared in it, it doesn't get dirty much! I realise some people might not be comfortable with this though. She also had cradle cap quite a bit and I just used a mixture of sweet almond oil with a few drops of lavender and rose essential oils massaged into her hair after it was dry. I know one day she'll need a little shampoo when she's older but hopefully she'll associate having her head massaged with being something nice.
