What shops in the UK sell hair extentions?

for real hair extensions that you can wash dry curly straighten crimp and dye:

boots super stores [ ie the bigger stores]

hair salons

the hair shop [in Chester, England]

for fake hair that isn't much good after two brushes but good for last minute partying:

supermarkets

markets

primark

peacocks

chemists [sometimes not often]

sometimes gown shops will sell them [more like the prom dress shops that aren't very big just local]
