Is this folliculitis, ringworm, alopecia or some sort of acne?

My 4 year old daughter has a little hair along her hairline and nape but not as much hair as throughout the rest of her head.  There are pimple and non-pimple bumps along her hairline and nape.  They're also throughout the rest of her head but not as much as is present along her hairline and nape.  I braid her hair or put her hair in ponytails but need to do something, though I don't know what, about the bumps.  She does play with sand which sometimes get into her hair.  If there's a shampoo or cream I should use, not use grease or any hair product or if I need to wash her hair more frequently, please advise. Is this folliculitis, alopecia or some sort of acne?  Please help.  Thank you.

Hi,
Seems to be a case of folliculitis.
Folliculitis is the inflammation of one or more hair follicles. The condition may occur anywhere on the skin.
Folliculitis starts when hair follicles are damaged by friction from clothing, blockage of the follicle, shaving or too tight braids too close to the scalp [traction folliculitis]. In most cases of folliculitis, the damaged follicles are then infected with the bacteria Staphylococcus (staph).Usually presents as pimples or pustules located around a hair follicle which may crust over .Typically occurs on neck, axilla, or groin area.
Topical antiseptic treatment is adequate for most cases.
