bullet Answer : Every morning, after a good hair wash, your hair looks very nice and clean; but as evening sets in, it starts looking greasy, lame, and lank. This is because you are suffering from a common hair problem that many people suffer from, the ‘oily hair’ problem. Most people think that oily hair is the result of an oily scalp, but that is not true. In fact, a dry scalp causes the sebaceous glands to produce more oil, which later gets transferred to the hair strands. Straight hair moves the oil quickly away from the scalp, whereas kinked hair moves the sebum very slowly away from the scalp.
