This sounds like it could be a couple of things. Shingles or an allergic reaction. Fortunately, both of these can be treated easily with natural methods.
For shingles, you can do the following treatment:
Rub 100% pure aloe vera gel on the blisters every two hours at night and during the day rub calendula cream on them. These will soothe the itching and help fight the infection. The other thing that needs to be done is the boostin of your baby's immune system. This can be done with silver solution, Echinacea, goldenseal, olive leaf, or oregano oil. It is important to seek the help of a natural help specialist so that you can be sure of the proper dosages with the treatment of an infant.
If it is an allergic reaction, the first thing you need to do is determine what in the baby's environment is causing the reaction. Since it is on your baby's scalp only, some key causes may be shampoo, laundry detergent, or a cap that your baby is wearing regularly. Remove one of these things from the baby's environment and if you do not see any improvement in two weeks, try removing one of the other things until you determine what is causing the reaction. Some simple things that may help are switching to a shampoo that is unscented as the scenting agents are often the cause of a soap allergy. The same applies for the laundry detergent.
