Is the cheaper salon the less experienced salon? Not always, you have to consider geographically where the salon is. In you higher real-estate areas the rent and cost to do business there is always higher. Higher overhead will have to bring prices up. So sometimes driving to the less expensive areas pays off. Not only can you find your price range you may find the stylist you have been looking for!
Sometimes salons are trying to expand their business or are looking for new clients and will give a super discount just to have you try them. You can always google them and check out their website, reviews and stop in there to pick up a business card to check it out.
