Hello,
Dandruff can be due to two reasons:external or internal. Internal causes include hormonal imbalance, poor health, poor hygiene, allergic hypersensitivity, lack of rest, emotional stress, excessive consumption of sugar, fat or starch and heredity predisposition.
External causes include excessive use of hair sprays and gels, improper use of hair-coloring products, cold weather and dry indoor heating, infrequent shampooing of the hair or inadequate rinsing of the scalp and hair.
Sometimes an allergy to dairy products, nuts and chocolates may cause dandruff, in which case you should avoid them for about eight weeks to be able to access its effect.
Eat a healthy diet. You can also take vit B6 and vit A and E which are good for hair and skin. Try medicated shampoos for dandruff. There are a number of over-the-counter shampoos available that can help. The most effective ingredients -- antimicrobials -- to look for are zinc pyridinethione, selenium sulfide, sulfur and ketoconazole (also available by prescription). If your hair is colored, don't use products with selenium sulfide or sulfur.
If the symptoms persist please consult a trichologist for the confirmatory diagnosis and treatment.
Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.
