Hey, if you want the best one FOR you, it depends on what kind of hair you have. Generally, all hair types love stuff like argan oil and olive oil based hair products. Stop using cheap ass shampoos. Trust me, your hair will thank you. As for your face, just focus on keeping it clean using the right soap (avoid yegela samuna), stay away from the sun and on weekends, use home remedies you see on Facebook etc. After that, you can try different creams that "feels" the best. Avoid creams that have a very strong smell.
