I tried the “no shampoo” idea for a while. Several months, in fact. The grease, the flakes, the juggling sugar and baking soda and salt and honey and vinegar and lemon juice.
Did wonders for my hair. Nothing for my scalp. I have tried for a couple of months now using this http://www.jason-natural.com/products/dandruff.php a couple of times a week. It’s missing a couple of ingredients that I feel were irritating my scalp that are in most shampoos.
I can’t stand the smell, so I use a tea-tree conditioner on the rest of my hair after the scalp treatment is complete. Treat the middle to back of the hair, not the scalp, with my preferred conditioner.
Excellent results so far. I’ve had one dandruffy flare-up in the past few months, but it was more stress-related (I changed some mood altering medications in my regimen) than a failing of the new product. Most dandruffy products fail on me after two or three weeks, puts me back at square zero.
