Please check and let me know what is this on baby's scalp.

I am little worried.

It is normal ..sub babies k hota h isko hataye nai..ye dheere dheere khud hat jayega...isse bachhe ka taalu ka bhaag majboot rehta h..AP isme roj oil lagaya kare

Nothing to wprry... It's quite normal in small children. That looks like cradle cap.. my baby too was having this. Doctor suggested to stop oiling for few days and also prescribed a medicated shampoo...You can check out with the paedtrician for shampoo.
