I had the same problem. Dark hair, itchy flaky scalp. Not a good look when you're explaining to strangers that you really do wash your hair!!I don't have experience with the dreadlockshampoo.com tea tree rosemary bar, yet. I actually think I'm going to order a couple bars today. I do have experience with the Satsuma and Nag Champa bars, the Dragon's Blood and Patchouli liquids.The liquids first: they're perfect for newer dreads. They help create knots and help with tightening up. And of course they smell divine. They do dry out my scalp tho. My dreads are mature, so I most likely won't buy them any more. They clean really well, but it seems I need to use a bit to get some good lather. I know it may not be necessary, but I like bubbles.The bars now: they're better used on more mature locks. Since you rub the bar on your roots/scalp, even lightly, it can cause some backwards progress. Just gently massage into your scalp and you have excellent lather and clean skin. And they smell divine as well. They leave your hair soft and fluffy and clean. I don't think the bars dry my skin as much as the liquids tho. The tea tree rosemary bar was created for dandruff/flakes/itchy tho, so that would be the best bet for that problem.I switched back to bs/acv with tea tree, rosemary and lavender oils to help with my problem scalp. It's been amazing. Since I went back to that way I have notice incredible changes in my dreads and my scalp is super happy again. I've fallen back in love with my head again
