I've been using Mitchell's Wool Fat for bathing and shampooing, and it's terrific (both the shaving soap and the bath soap). I've had itchy scalp in the past, and that has gone away. Great stuff.
I use rosemary and mint shampoos. My hair grows fast, strong, and very healthy. I wear my hair long so it matters to me.
Let us know how it is! It looks like pretty good stuff - both the Duke Cannon and Duffy's (especially since I love me some beer).I'm generally indifferent to shampoo. I have thick hair, and anything seems to work. Prell, Breck, Suave, etc. I've been using Duke Cannon because I like their marketing. But today I acquired a bottle of Duffy's Brew, which is made out of beer from one of my favorite local breweries, Elysian. I'm excited to try it!
My wife and I just subscribed to the Queen Charlotte soap of the month with shampoo bar option. For $75 we get two body bars and 1 shampoo bar each month for 6 months. Shampoo bars are great for your scalp as they don't tend to strip moisture and proteins from your hair like most commercially available shampoos. I'm rather surprised Stirling hasn't delved into the shampoo bar market yet.
