I have just used a keyword density calculation formula as suggested on this site (How Search Really Works: The Keyword Density Myth | Search Engine People | Toronto)

And the total word count on my page is 2775...... the keyword "hair extensions" is used 72 times, which gives......

72 / 2775 = 0.0259 * 100 = 2.59%


Im sure someone said anywhere between 2& and 7% is average/good.
