I have a skin rash with a lot of itchy bumps all along the scalp on my forehead. Can you help me figure out what it could be?

It is recommended to try to determine a possible cause for the itching and avoid it. Look for any changes like a new cream, soap, shampoo, hat, etc. Applying cold compresses may help calm the reaction. If that doesn't work, you can try using a hydrocortisone cream or an antihistamine like Reactine, Claritin, or Aerius. If the treatments are ineffective or the condition worsens, it is best to consult a doctor.
