Hi guys. So i have a friend who'll visit London soon and i want to ask her to buy me some hair dyes while she's there. I know Directions is from UK, but I'm not sure what stores carry this brand. It'd be great if it was in a chain stores so it'd be easy for her to find. I also welcome recommendations for other brands. Whatever cheap and easy to find in London basically.
My last resort would be ordering it online and then ship it to her hotel. Now if this is the case, can you tell me how long shipping usually takes time?
