Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that your son is suffering from Seborrheic
Dermatitis thatleads to Dry and flaky scalp that itches ..
It can occur due to causes like
Fungal infection, stress, side effects of certain medication, genetic causes etc..
I would suggest you to consult a Trichologist and get evaluated and a thorough clinical evaluation and investigations like microscopic examination of flakes can help in diagnosis and treatment can be planned accordingly..
He can advise you to wash your scalp and hairs with shampoo containing
Ketoconazole, coal tar,
salicylic acid, Zinc and
selenium..
You can be advised to massage your scalp with steroid lotion..
Sulphur containing shampoos are also helpful..
Keep your scalp Dry and clean..
Avoid retention of moisture in scalp..
Hope this information helps..
Thanks and regards.
