I think you are correct Mubeen, if you have constant lesions on your scalp you should see a doctor to determine if it seborrhea dermatitis, dandruff, or a fungal infection. psoriasis cannot be cured. i am using zinc shampoo on my hair and massage it into my scalp. i let it on my scalp for about 5 minutes then i rinse really well. i also apply a moisturizer and a sunscreen to spots on my scalp. it eases up during the day but by the next morning i have to repeat the process or have major skin scales. keep the area moisturized.
