How do u get dandruff?

I had terrible dandruff for two years and tried every shampoo in the market. Actually, it mostly happens when your scalp gets too oily or if there's sweat buildup, which feeds the yeast. What worked for me was using a proper ketoconazole shampoo twice a week and keeping my comb clean. Don't oil your hair too much, it just feeds the fungus.

Same here, had this issue last winter. Keeping your scalp dry after a shower and not sleeping with wet hair helps a lot to control it.

I get so stressed when my scalp starts itching because I worry it's a sign of some bigger skin infection or lack of vitamins. It really flares up during exam stress or weather changes. Try not to scratch it too much or it might get infected, maybe just wash it gently with mild lukewarm water.

Please be careful before applying lemon or baking soda like people suggest online. Sometimes what looks like simple dandruff is actually psoriasis or eczema. It is always safer to get a dermatologist to look at your scalp once so you get the right treatment.
