My hair is very strange?

Some days it is oily, some days it is dry. It get's tangled easily and it is fairly thick which makes it harder for me to style it. I style my hair in simple ways i do not use creams or sprays, i use all nature beauty products. I oil my hair three times a week with almond oil. I need some advice on how to tame my hair when it is dry, or to keep it neat when it is oily. Any home remedies or advice?
