Dennis Williams is a supplier of hair/beauty products to people who work in that trade. My friend is a hairdresser so I go with her sometimes. They sell a really wide range of dyes, make up, waxing equipment, shampoos, and much more. Personally I expected them to be cheaper as they are supplying to trades people but the shop is quite expensive. Having said that they obviously sell the ‘top of the range’ things as well as large sized items so it maybe isn’t too bad value for money. The staff are very helpful with finding things and the shop is located on the industrial estate so there’s parking space outside.
