Hair salon product in the news for possible injuries to consumers

When discussing the difficulty of making the distinction between sales and services for products liability claims, I often use the example of a hair salon that uses a product on a customer's hair. Is the hair salon "selling" the product (which could make it subject to strict liability for defects in the product as a seller in the chain of commerce) or is it merely providing the service of applying the product (which would not). Along those lines, I just came across this story in the PopTort Blog about claims that a certain, and apparently very popular, new hair salon service/product is placing workers and customers at risk of serious injuries. Several lawsuits have been filed already. For more details go to The PopTort.   For a couple of news reports/videos on the issue go here and here.
