Interesting concept.
The controls are a little tricky to understand at first and kind of slow, but after learning them it gives you more control over which action you get, with intervals between the different sections being used to cancel an action if you don't want it, which I thought was quite nice.
I think that the sequences required to shape the hair as needed could have been explained better, but overall it's intuitive if you understand what the different hair styles look like.
One piece of criticism I have which could have made the game better would be improving the randomiser for deciding which hair cuts so that the same haircut doesn't appear twice. On one stage there were three or four customers in a row that asked for an afro when I played. This isn't too much of a problem but I think it would make the game seem like a slightly more polished experience.
Overall, solid game and well done for adding music and sound!
