Brixton vs Chelsea

Most of the shops I am visiting in Brixton for my project are specialized in African Caribbean hair and beauty products. These products have been specifically developed for Afro consumers and they are generally not available at most high street shops in the UK.
They stock natural human hair wigs, hair extensions, hair braids, hair dryers, black skin care products, afro wigs, hair sprays, oils, moisturizers, gel, hair dyes, hair straightening irons, and everything else you can imagine related to hair.
Most of the salons in the area use these products with local costumers all the time and it is regarded as an important part of their identity, but it is also a big business with other kind of costumers willing to pay huge amounts of money for different reasons in areas like Chelsea. After a few frustrating days wandering around the streets and talking to everyone who wanted to listen to my stories, I am finally getting access to slighty more deep situations with some of the hairdressers and clients in both sides of the industry.
The original idea was to follow the process of buying hair in Brixton and using it in Chelsea by one of the girls working in a posh salon, but maybe it would be more interesting to compare these two opposite worlds in a new way, and raise some other issues potentially related to the main subject, like race, social exclusion or aesthetics in different parts of the world. Basically I haven’t decided yet how to organize the project, so every comment is more that welcome.
