Hi dear user,
Zinc pyrithione is best known for its use in treating dandruff and seborrhoeic dermatitis
. It also has antibacterial properties and is effective against many pathogens from the streptococcus
class. Its other medical applications include treatments of psoriasis, eczema, ringworm, fungus, athletes foot, dry skin, atopic dermatitis
, tinea, and vitiligo.
Usually it does not cause dry or rough hair but excessive use or abuse can cause it.
Frequency of twice or thrice per week is recommended.
