Oily hair is normally caused by an oily scalp. Normally people with excessively oily scalps eat diets high in fat. Your hair is fed through your scalp with sebaceous glands which produce sebum and oils. If your diet is loaded with fried foods and saturated fats from meat and dairy products, you will of course trigger an over production of sebum, and this will lead to an oily scalp and oily hair.
To start treating oily hair, it is always best to start from the inside. Cut down on the amount of unhealthy fats that you consume. This will make a big difference to the appearance of your hair, as well as the appearance of your body.
Lots of people think that they can use strong shampoo with harsh detergents to treat oily hair, but this only dries the scalp and causes flaking. Make sure that your shampoo doesn't have sodium lauryl sulfate or nitrosodiethanolamine (NDELA) in it. Go for organic shampoo's and you will find that they don't include the above two chemicals.
Give yourself a natural rinse to help your hair to be more manageable and shiny. Do this rinse after your shampoo to close the cuticle, which is the outer layer of the hair shaft. This will create shiny, smooth hair that feels thicker and is more manageable and less oily. Here are some ideas for natural rinses.
For the first one, squeeze the juice from two lemons into two cups of distilled water. Put the liquid into a plastic bottle with a spout or a spray bottle. After shampooing, blot your hair dry with a towel and smooth the liquid evenly though your hair and scalp. Leave it on for about five minutes and then rinse with tepid or cool water for maximum shine.
Another great herbal treatment for oily hair is the herb horsetail. Horsetail strengthens the internal bonds in the hair shaft and reduces the oiliness. Start by boiling a cup of distilled water. Put two tablespoons of dried herb in a pan and pour the water over it. Steep for about fifteen minutes and then drain off the liquid. Cool and put in a bottle with a spout or a spray bottle. Use it as you would the lemon mixture above.
Another great treat for oily hair is rinsing with three to four drops of one of the following essential oils in a base of one ounce of borage-seed or evening primrose oil. You can use either lavender, rosemary, cypress, eucalyptus or lemon oil as these are all astringent and will cleanse and tone the sebaceous glands.
Following the above advice should go a long way to improving the condition of your oily hair and ensuring that it looks beautiful, shiny and manageable all the time.
