Hi, Welcome to HCM, The rashes can be due to allergy as she used the shampoo that she should not have used. Children have delicate sensitive skin. Antihistamine Syrup and mild medicated lotion/cream can be of help. Do not let her scratch. It is important to rule out any fungal infection, viral infection. Get her examined clinically by a doc. Diagnosis should be made early to start the treatment, she will need antibiotics and ointment surfaz to be applied locally if ring worm infection is detected. If it is measles, symptomatic treatment should get started as it is a highly contagious disease. Maintain hygiene, get her treated, take care.
