Welcome to Healthcare Magic forum.
only on head (I assume scalp) is not a very common condition.I assume that the doctor has provided you with a diagnosis like Atopic dermatitis
.Infants having scaly, itchy lesions in scalp can also have a seborrhic dermatitis or some infection like fungal or bacterial.
Lozisoft lotion is just a moisturiser containing liquid paraffin
and is safe for infants.
It is usually given for dry skin
conditions or atopic dermatitis.
However if your baby is not responding well to it , she can possibly have an allergy to any of the ingredients or fragrance used in the lotion.Also if her scalp lesion is not resolving then please consult your doctor again for reviewing the diagnosis and providing an alternative medication.
There are many similar emollients or moisturisers available of different brands like aquasoft, calosoft, nmf_e, etc
Your doctor may prescribe an alternative for solving your problem.
Wishing your daughter a speedy recovery.
