bumps on scalp

I have a patch of bumps on the back of my head and on the top. Might have been from when i got my hair cut at the barber shop. Is there anything out there I can use that will clear this up.

Hi,
This could be folliculitis if the bumps are painful.Folliculitis is the inflammation of one or more hair follicles.
In most cases of folliculitis, the damaged follicles are then infected with the bacteria Staphylococcus (staph). They enter the follicles through cuts caused by shaving or traction or blockage of the follicles.

They present as pimples or pustules located around a hair follicle. Topical antiseptic treatment is adequate for most cases.  
Topical antibiotics such as mupirocin or neomycin containing ointment can also be applied on the bumps.

If the bumps are itchy then it could be due to scalp seborrhoea. It  is a skin disorder affecting the scalp, face, and trunk causing scaly, flaky, itchy, red skin.
Treatment is with shampoos containing coal tar, ciclopiroxolamine ketoconazole, selenium sulfide, or zinc pyrithione.
