My baby is less hair on scalp. She is good thick hair when born. We removed her hair completely on her 13th day, after that also thick hair has grown. Then i found cradle cap on her scalp and i again removed her hair when she was 2 month old. After that her hair is not thick as before,. There is tiny hair on the root, but is not growing from there. Now she has somewhere thick hair and somewhere thin hair. I used to apply coconut oil or almond oil before bath everyday. Give some suggestions to grow the hair from the root.
