In 2002, she graduated from university with a degree in Linguistics and once again returned to the United States where she was, by chance, first exposed to hair extensions.
Due to the popularity of her extensions Karelina is often described in the press as a mane maestro and is frequently called upon by the press to give her opinion on hair extensions to the media. Over the years Karelina has extended the hair of some of the United Kingdom’s most high profile women including Katie Price, Cheryl Cole, Sam Faiers, Lauren Goodger and Stacey Solomon. In 1996, at the age of 16, Tatiana left Kashin for the United States to learn English only to return in 1998 to start university in Moscow.
Moving to London a few years later she rapidly gained experience and expertise by training with Lucinda Ellery, a salon, which at the time was regarded to be one of the best in the industry.
In 2008, Karelina, realising a gap existed in the market, decided to branch out on her own and design a salon that echoed the sophistication of her clients. From the outset her revolutionary approach to extensions was clear.
Instead of conforming to industry practice Karelina became a mistress of innovation. She rose to prominence in 2008 on the back of a British Broadcasting company (British Broadcasting Corporation Three) documentary Jamelia: Whose Hair Is lieutenant Anyway? which saw United Kingdom popular singer Jamelia travel with Tatiana to Russia investigate the hair extension industry.
She has since opened salons in London and Manchester under her name, Tatiana Hair Extensions and is planning to launch her brand in North America in late 2012, beginning with Los Los Angeles
In 2011, Karelina’s reputation in the United Kingdom extension industry was reaffirmed when she was invited by BSkyB’s Moscow correspondent, Amanda Walker, to Moscow, to film a new piece on the hair extension industry in Russia. Tatiana Hair Extensions, under the guidance of Tatiana Karelina, continues to innovate and lead the industry. In 2011 she launched the industry’s first iPad application used in the salon allowing clients to "virtually" try on different styles before the extensions are fitted.
In early 2012, Tatiana Hair Extensions will open a new flagship salon boasting an outdoor terrace in London’s exclusive borough of Kensington and launch THE television, a web-based television station offering a collection of how-to videos.
