I have dandruff in my hair and an oily scalp too.

AM routine:

2% Sali-Cinamide Anti-Acne Face Wash with 2% Salicylic Acid + 2% Niacinamide

Re’equil Moisturizer with Hyaluronic Acid

PM routine:

Same face wash

Minimalist 2% Salicylic Acid Serum

Moisturizer same

I barely drink water — probably only around 500 ml a day. How can I fix my dandruff and oily scalp? Also, are these products/routines okay, or should I change anything?
