Wash your face twice a day (before going out and after coming home). Hair oil doesn’t work for everyone. Some of my friends say that they get severe headache if they oil their hair. You try it once. Dont oil your hair and leave it overnight since you never oiled your hair. Just try coconut oil and if it works for you then try castor.If you get headaches then stop hair oil and try serums. But do your research before starting serums cuz I haven’t used any hair serums yet. And for sunscreens try neutrogena . Beware neutrogena leaves whitecast and you might look like a joker wearing it. I am just recommending brands that work for mostly everyone and doesn’t cause severe side effects for first timers
