I too have naturally crazy curly hair, and my best friend is a stylist, so all her new color techniques get tried out on my hair. (fun right? Not really) I stopped shampooing completely last year and it has been the most amazing thing I've ever done. I spent an embarrassing amount of money on shampoos conditioners and products to tame my curls, and the best thing so far has been NO product!
I cleanse with a baking soda/water mixture. It doesn't lather like a normal shampoo but I got used to it. I rinse with a apple cider vinegar/water/EO mixture to neutralize the baking soda and help close the hair cuticles.
I now wash my hair at night, brush it, then sleep on it wet, and wake up with perfectly amazing curls.
I've read that some people go through a 'greasy' phase when switching to this method where the scalp is shocked and starts over producing sebum. But I only washed my hair once or twice a week at the most to begin with, so my head never had to get used to the new routine. It wasn't instant results, but after a month, omg... amazing!
the recipe for the wash is
1 quart boiling water
1/4 cup baking soda
mix and pour into squirt bottle
sprinkle the baking soda into the boiling water otherwise it can go PFSHHH
(ask me how I know lol)
the rinse is
3/4 cup water
1/4 cup apple cider vinegar
bout a quarter tsp of your favorite eo
(i use rosemary, 5x orange, and tea tree)
I also pour in about a tbsp of safflower oil as well.
I've read that some folks use honey, but if your hair is prone to frizziness in humidity, I would probably avoid humectants just in case hehe
Lemme know if you try this and how it works! It is also really fun to take before and after photos of your hair to see the progression
