www.sumru.co.uk/collections Sumru is a U.K. based black woman owned business. With Sumru products, you can rest assured knowing that we wear the hair we sell and test it according to our standards. Our hair can be fried, dyed, laid to the side – and still maintain its quality. That’s the standard that we believe in. It’s the standard we all deserve. Sumru hair extensions are for those who enjoy opulence and luxury. We source our hair from various countries in Asia based on our quality standards.
