Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain dandruff or Seborrheic
Dermatitis is one of the most common reasons for hairfall and you need to consult a Trichologist and get evaluated..
He can advise you to wash your scalp with a shampoo containing
Ketoconazole,
Salicylic acid, coal tar, Zinc, selenium..
Massage the scalp with a Steroid lotion..
You can also put few drops of lemon in warm coconut oil and massage your scalp with it..
For Acne marks you can wash your face with Salicylic acid and
glycolic acid containing facewash..
You can apply creams containing Kojic Acid, Glycolic acid and arbutin..
You can also also apply Vitamin E and C containing creams..
You can limit sun exposure and always apply sunscreen lotion when exposed to sun..
Exfoliate your skin twice a week to remove dead skin layer..
You can also go for treatment like
Microdermabrasion and chemical peeling.
Hope this information helps..
Thanks and regards.
