Hi there! I've lived in Florida as well as Singapore. No, never got completely frizz-free, but the CG method did help to drastically reduce frizz. I absolutely cannot use glycerin based styling products in the humidity. If the glycerin is further down or listed after an anti-humectant it can be ok but generally I have to stay away from glycerin.
Technique is also important in eliminating frizz, rising with cold water, gently squeezing out hair with an old cotton tshirt and not touching while drying have made the biggest difference.
At the end of the day you may still have a little frizz, just roll with it.
I visited my grandma recently and she has super frizzy hair that she puts up in a beehive-ish bun and it looks super cute! It made me think that frizz isn't always so bad, sometimes it can even have its charm!
