I noticed most women wore relaxed/straight styles, but I saw plenty of people -- men, women and kids -- with locs. I only saw a handful of free form naturals/fros. I've heard/read on other blogs that natural products are a bit harder to find in T&T. I visited a few stores to see what kind of hair products the average person might score. It was pretty much the same as what you'd see in an average BSS -- lots of petrolatum, mineral oil, etc. I did notice the full line of Herbal Essences products.
As for my own hair, I was all over the place. Because I swam in the ocean several times and took multiple showers a day due to heat and sweating, my plan for wearing twists the entire time just did not hold up. I did twists, twist-outs, wash-n-go, puffs, and even had my friend do a couple of french braids one day. Shea butter was my bestie for sealing and those basic styles. My wash regimen didn't seem to be as effective, perhaps because the water was... harder? It reminded me of West Texas, where soap didn't lather quite as well. Even my normally very sudsy Dr. Wood's Shea Vision Liquid Black Soap didn't froth for me. In the end, it didn't matter much. Hair was easily a distant second to the daily activities, rest, great food, etc.
More to come on Tobago :)
