First of all when you choose an esthetician you want to find someone who fits for your concerns and needs. One esthetician could be good for your friend, but not good for you.
The bad news is, you can't really be sure if she will be the right for you until you go in and experience any kind of service. Definitely a good point if she has a website, because you can get a picture of the salon and of her, you can see what kind of services and treatments she offers, what lines she carries and hopefully you can see the prices too. (I don't like spa websites without prices.) On this basis you can decide if you want to give it a try or not.
The fundamental question is what kind of service you want. The expectations are different depends on the service you want, eg. waxes, makeup, eye lash and brow tinting, or facial treatments.
