I have washed Asha's hair probably 6 times since she has been born and she is nearly 14 months old. She doesn't have much hair at all. I don't use soap either, just water and a flannel. If I need to use soap I just use the tiniest little bit on the flannel and wash her that way. I also rub her head with the flannel and until she gets more hair or gets sand etc in it then I will stick with not at all or very rarely.

Cheers
