There are plenty of manufactured hair products on the market, which include drying alcohol, mineral oils and mystery preservatives. Steer clear of the unknown -- instead, make your own hair volumizing treatments with the help of natural ingredients, like sea salt and rosemary, for shiny, voluminous strands.

This spray gives your hair that natural, beachy texture and smells like an island alcove. Combine one cup of hot water with a heaping tablespoon of sea salt and another heaping tablespoon of coconut or argan oil in a spray bottle. The salt builds up volume while the oil gives your hair a boost of shining moisture.

Shake up the ingredients in the spray bottle until they are all incorporated -- about a minute -- and make sure the water has cooled before use. Spritz the product onto your freshly washed, damp hair. Scrunch your strands as you spray and allow your tresses to air dry for a naturally voluminous look perfect for summer.

Avoid shampoos that include sulfates, which tend to dry out hair and leave strands limp and lifeless.

Here's a quick hair fix that gives you instant volume without the mystery chemicals. Mix together 2 tablespoons of corn starch and rice flour each. Then add three to four drops of rosemary oil to the mixture and incorporate completely. Place the mixture into a clean salt shaker. The starch and flour create volume near the roots and lift the hair strands, while the rosemary oil stimulates hair follicles.

Apply the mixture near the roots of your hair for an added boost of volume. Alternatively, apply some powder at your roots before bed to let the product do its work while you sleep.

Combine a tablespoon of coconut oil with a 1/2 cup of water in a spray bottle for a light, quick-fix spray on any dry or frizzy areas that need a boost of moisture.

Voluminous hair comes from removing any leftover products or heavy residue from sulfates in shampoos and other styling products. These residues weigh down natural volume. Remove this volume-killing burden with an acidic rinse. Mix together a cup of apple juice, 2 tablespoons of apple cider vinegar, the juice of half an orange and the juice of half a lemon.

Stir the ingredients together and comb the mixture through your dry hair. The acids in the juices remove any oil, dirt or sulfate buildup naturally. Allow the mixture to sit in place for about 20 minutes. Then jump in the shower and continue as usual with your normal shampoo and conditioner.
