According to http://beauty.excite.co.uk/cactus-oil.html cactus oil is high in fatty acids which aid in preventing and reducing hair loss. It also contains vitamins and minerals that help to promote healthy hair and protect bonds. Cactus oil has high concentrations of vitamin B5 which helps the cactus plant to store water for much longer this in turn when used on hair helps hair retain moisture for longer. This makes perfect sense because cactus thrives in dry, arid almost desert like conditions and therefore needs to be able to store water for a long time in order to survive. So in essence cactus oil has moisturizing properties that coat hair with layers of protection just like the plant needs to survive in dry conditions making it great oil for dry and damaged hair. Cactus oil is also known to smoothen wrinkles and revive dry and brittle nails.
I would really love to try it in its pure form first if I can find it before buying Cactus oil products that have other ingredients in them. Most of the ones I found online had other ingredients in them. Apparently there is a genus of cactus known as prickly pear cactus which is the name most people may be familiar with. What I am not sure of is if all the genera have the same properties or from which genus cactus oil is derived from.
