I came across a post on MuslimahBeauty, (You have to check out this blog) a blog about all things fashion and beauty, about a bizarre practice of using Coca Cola on your hair to achieve bouncy curls.
Hmm... Bizarre Right. How did anyone even think of this?
From the ingredients I was able to get from the internet, I found that Coke contains lime extract, caffeine, phosphoric acid and glycerin. It probably contains a whole lot more than this but it is a secret recipe.
The ingredients that were interesting are:
Glycerin, a humectant draws moisture into the hair
Caffeine, regulates and aids hair growth even when applied topically
Lime Extract has a regulatory effect on the production of sebum and can have a detangling effect.
Phosphoric Acid which is used in many baldness remedies is used to control the pH of cosmetics and personal care products.
Coke has a pH of around 2.5 - 3.4. A Ph of 7 is neutral, this is a logarithmic scale however, so a Ph of 2.5 is very acidic. This is probably mostly likely due to the phosphoric acid. Table vinegars pH ranges from 2 - 4. The ph of our hair should be around 4.5 - 5.5. Many hair products, shampoos, hair colour and relaxers are strongly alkaline. Rinsing with Coke as with Apple Cider Vinegar could help to balance the ph of the hair.
I am not sure if the combination of ingredients in coke is 'good' for hair and we can only guess as the proportations and the other ingredients. I cant say I am advocating anyone to try this.
This is probably a safer way of curling your hair
There is a lot of information out there about Coca Cola used for all kind of things but most of it is anecdotal and I couldn't find any scientific study proving or disproving any of these results.
Do you know of any?
I found more observational and anecdotal information about using topically here:
Not to put you off drinking Coke, but I've used it to clear my drains.
Anyway I found it very interesting that people use this on their hair. I doubt that the acid and additives would be beneficial to long term hair care and as I said there is probably a whole host of other things in Coke than the ingredients I was able to find.
Was anyone brave enough to try this if so what were your results?
