Dandruf for a teenager :( sensative skin?

first of all using shampoo and conditioner daily in the shower is the wrong way to go the shampoo can strip essential oils from ur hair and scalp leaving a dry texture which is a cause for dandruff and i am not an expert but i had gone through this but i started using hair moisturizers and genuine oils like olive oil, jojoba oil, baby oil if that works and argan oil search up a whole buch of oils that are good for hair and moisturizers ...and use them it will hopefully work but i used another solution/mixture type of herbal remedies which include onion juice tea liquor olive oil and vinegar and some herbs like the ones u can find that are grounded to powdery consistency and mix it well and apply to your roots then shampoo it out and eventually if you do this every 1-2 weeks your flaky dandruff will be reduced .......this doesn't affect sensitive skin since its just oils and natural ingredients just limit the vinegar.....p.s.don't get me wrong this works for both genders
