Given the question: Read the following context and choose the correct option to answer the question. Context: Those of you who are regular readers of Beauty Best Friend will know that I suffer from a very sensitive, itchy scalp and I am constantly on the hunt for haircare products that are natural and non-irritating but that also treat my hair well and leave it feeling soft, shiny and clean. So far my experience has generally shown me that natural, SLS-free shampoos and conditioners do not irritate the scalp as much as their chemical filled cousins, but that they do not always clean the hair as well and can leave it looking and feeling greasy, sad and lifeless. One of the first SLS-free shampoo and conditioners that I tried, back in 2013, was Mild Shampoo and Gentle Conditioner from Naked. The relief that I got from my itchy scalp was almost instant, but I did find that it didn't remove grease and oil from my hair too well, and I had to wash my hair a lot more often. Since then I've tried lots of different SLS-free haircare products, all of which have had their benefits and downfalls. For the past month I have been using Rescue Intensive Care Shampoo & Conditioner from Naked, aimed at frizzy, dry and damaged hair. As I had found such relief from my itchy scalp when using Naked products previously I wanted to try out another variant to see if it cleaned my hair any better. Prior to using the Rescue duo I had been having a really hard time with my scalp, but after just the first use of these natural products the itching had subsided about by 75%. Both the shampoo and conditioner have a lovely rich almond scent which stays on the hair after it is dry. The conditioner is a thick, rich cream and it feels like it is giving dry hair a real treat. Unfortunately these Naked products still don't clean my hair as well as some other products, and I still feel that my hair can look greasy and lank the day after I've washed it. I have tried the 'reverse poo' method which helps a bit this means conditioning your hair first, then shampooing it second but my hair can get very tangled after the shampooing stage. Question: How long did the writer probably use the Mild Shampoo and Conditioner? Options: A. A few days B. Under a month C. For a couple weeks D. not enough information

C
