Babies and toddlers can often have build up on their scalp, but for different reasons. Whether build up on the scalp is from cradle crap from seborrhoeic eczema in babies, or toddlers non-compliance with thorough hair washing, a simple very simple treatment can be used. You just need two things, a small amount of Extra Virgin Olive Oil and a narrow fine toothed comb. A baby comb or a barbers fine tooth comb work well. Simply massage the scalp with Extra Virgin Olive oil and allow it to absorb for at least 30 minutes to overnight. Then gently brush out the hair. The cradle crap will come out easily through the tines of the comb. I used to do this with my 8 year old when she was a baby with cradle crap and it worked well every time. It was necessary to repeat a few times while she was little. My two year old did not have cradle crap as a baby, but she really is resistant to having her hair washed often. (She doesn't even like plain water over her head unless it is ocean water). So this treatment was necessary recently. I followed it up with a wash with my Patchouli Hemp Oil Shampoo Bar. She was a bit cranky to have her hair washed, but her scalp is back to normal and her hair looks great.
