Why it worked
The video leverages popular aesthetics ('Jessica Alba blonde', 'Alix Earle blonde') to create engagement and uses a direct call to action with a clear URL for a relevant service (hair extension certification), appealing to a visually-driven audience interested in hair trends.
Summary
Two women, styled with different blonde hair looks, are presented with the question of which blonde style to choose. The video implies they are getting certified in hair extensions at Habit Education.
