I have thick curly hair, which I've spent most of my life working against, so now I have corkscrew roots, pin straight ends, and with alittle moisture they get very curly.
With that said, my routine consist of using a Silk Elements (course) hair relaxer ( only every 10-12 weeks- it gets nasty up there if I don't )
after I relax I use Organic Olive Oil Root Stimulating shampoo, and Silk Elements conditionor.
I let it dry over night( ponytaled) and flat iron it the next morning using silk elements polishing gloss. Because I only relax every 10-12 weeks I usually only buy trial sizes of the shampoo, conditioner and polishing gloss. So it runs my altogether 6 bucks.
But thats only when I relax.
My normal routine is Garnier Fruitice Triple nutrition shampoo and conditioner and I let it air dry.
I've yet to find a good cream/gel/ frizz ease serum to work in compliment to it.
In the past I've used everything from pantene for relax and natural/ and their curly line, I've used tressume, and alot of black marketed products. They either stripped my natural hair oil ( Which I need, and then some, because it dry) or made my hair super thick. I'm satisfied with Triple nutrition, I think its all the oils in it. It has shea, Olive, and some Avacado.
Also, When I figured out Shea butter is awesome for my hair, I tried the cantu bottled oil. MY WORD my hair stunk from it. lol
