Finding claims on hair products that look dubious is quite easy. I generally maintain a healthy level of scepticism and it always surprises me when I find that some strange claims almost appear fictional may in fact have some scientific basis. Here are a few interesting ones that I have gathered over the years.
1. Garlic and onion for hair loss
Although garlic and onion are sometimes advertised as hair growth accelerators in truth they have only been shown to be successful in individuals suffering from genuine hair loss and specifically alopecia areata. The reason for success of garlic and onion extracts is thought to be because they help slow the immune system from attacking itself which triggers this type of hair loss. In the study crushed onion juice was directly applied to the scalp (Journal of dermatology, pg 343-346, 2002).
2. Crisco and butter for hair conditioning
Alice of Alice in Nappyland recently featured a traditional Ethiopian treatment kibae which is essentially freshly churned butter as a prepoo with excellent results. On hair forums, crisco is also being promoted as a pre shampoo treatment. Both of these share the common feature that they contain saturated fats which are thought to be able to penetrate hair in the same way coconut oil does (Journal of Cosmetic Science, pg 169-184, 2001). Therefore, there may be some truth to crisco and butter being good conditioners.
