Dandruff can cause hair loss and wearing a hat and keeping the hair unhealthy may cause dandruff
. For dandruff
, keep the hair clean and use shampoos containing coal tar preparations, pyrithione
zinc, salicylic acid, selenium sulfide and ketoconazole.
You may need to alternate between types of shampoos if one type initially controls the dandruff but later loses its effectiveness.
I hope it helps. Take care and regards.
