Well, I live in the Dominican Republic and I am having a hard time here too.
Me and my friend (only 2 people I know here on shampoo free method) are almost in panic because we don't have as many CG-friendly products available, even curly hair products are difficult to get! a very very low percentage of the girls wear natural hair. The trend is to have straighten / relaxed hair.
To give you an idea, the only silicon-free conditioners I can get at a department store/ drugstore are Suave Naturals and Tressemme Naturals, and suave is not as good as Tressemme. I can co-wash, but I can't leave any product in my hair. It gets puffy.
It's been 2 weeks since I starting looking for it. My bottle has only 1/4 left.
Hope they come back soon
