What shampoo are you using? I highly recommend fairy tale products for baby’s and kids (daily wash for babies, rosemary for older to prevent lice when going around other children). Ik my nephew struggled with a dry scalp with Johnson and Johnson, it could either be baby’s natural oils or the shampoo could be too dense for your baby’s scalp 🤷♀️
This happened every time we used Johnson’s products on the hair. I use aveeno hair and body wash for her hair and this keeps it looking clean x
I think this is just baby’s natural oils, my little one is the same
