Oily hair is such a negative feedback process.
Your body is producing oil because it is receiving word that your scalp is too dry. In other words, oily hair is really a solution to dry scalp conditions, not a problem in and of itself. Dry hair is not a sign of oil slicks, however, and often results from over use of coloring agents, perming, heat curlers, and electric hair dryers. According to a New York stylist to the stars, gentle moisturizing shampoo is your best bet for both oily and dry hair. Your gender and the length of your hair shouldn't impact its oil content, nor your awareness of it.
