Your daughter is having most probably atopic dermatitis
There is cradle cap on scalp..dandruff like lesions on scalp.
There would be dry mild scaly erythematous patches on face , neck,legs and trunk. And that would be irritating and itchy.
Apply mild steroid cream like mometasone with antibiotic cream like gentamycin
Avoid soap, use dettol liq. for bath.
Cleanse the scalp with savlone liq.
Use moisturing cream on whole body after bath in the morning...like emolene cream.
Give her antihistaminic syp. like hydroxyzine
..atarax syp 5 ml twice day.
Antbiotics susp like roxithromycin
5 ml twice day may be given.
If there is severity, give her prednesolone syp in tappering dose.
Avoid woolen clothes.,keep away her from dust,perfume,powder..etc
I think, she may be improved... Still , consult dermatologist
I hope you got my answer.
