Vegan-Friendly Salons and Spas in Milwaukee
The Establishment - A salon and spa on the east side using Aveda products. They got some great reviews on Twitter, so you should probably check 'em out!
Roots Salon - They have two locations: Brookfield and Greendale and they offer Pureology hair care products, which are 100% vegan.
The Knick Salon and Spa - A spa right in the heart of downtown Milwaukee that offers vegan options. Get the same variety of services you would at any standard salon, but with products and treatments that are natural, organic and vegan. Verify which products are vegan when making your appointment.
Halo Hair Spa - This salon and spa on Brady Street offers the DermOrganic line of products which are vegan.
Aveda Salons - I was able to confirm directly with the company in 2010 that the majority of Aveda products are vegan. Get a list of which are not vegan here. There are many salons in the Milwaukee area that use Aveda products. You can search here to find one near you. Update 2012: Because they have decided to sell in China, Aveda is now required to test on animals since China requires it by law. It's a total bummer and I'm now transitioning myself away from the products as a result. Get all the details here.
