Vision on Brick Lane offers two leading hair straightening techniques; the Yuko system and the Keratin Brazilian blow dry. Both claim to add shine to you locks as well as straightening, but Keratin's the better choice for curly, frizzy or damaged hair.
For a cheaper, short-term treatment, try Compton Hair's X-Tenso in their Barbican salon. This light chemical smoothing system will give you relaxed, smooth curls for six to eight weeks. So now all you need to do is track down a handsome prince.
