Sephora,
I can only enthusiastically recommend the technique I use:
CO washing. That is Conditioner Only washing. Conditioners have the same ingredients in them that shampoos have to get your hair fully rinsed off. Depending on what you usesI do not use shampoo anymore, and I haven't for several months. If I need an actual detergent to wash my hair with, I use a Tea Tree oil wash.you will never have another itch again if you keep your scalp clean. I discovered how well my hair actually did without the use of sulphates and silicon found in so many commercial shampoos and conditioners.
I also henna & Indigo my hair, and it actually has loosened my curls ALOT, and strengthened my hair, it's nearly indestructible now, it seems.
I don't get flakes or itch anymore. I used to use Head & Shoulders, Pert Plus all those harsh shampoos when I would get flakes. I quit using them, and put miconazole (yeast infection cream) on my head one day a long time ago... I have never had another outbreak of flakes.
Also, do not use anything that is petroleum or mineral oil based. It only causes problems for your scalp down the road. Throw them all out.
PM me if you are interested in the rest of my regimen.
