Hi everyone, you have all been so helpful with my queries. I have one more (can't catch a break, can you? Lol). Due to a health condition, I have had alot of hair loss and have found that using Nioxin shampoo has helped in the past. I am looking for it again, and would prefer to get it in Ottawa, rather than online. Is there anyone in the hairdressing field that could advise me where to find it, and in choosing which formula I need? Many thanks
