Not Great for Course/Thick Hair
I tried these on wet hair applied with my usual curl creme and let them sit for two hours. I only achieved some wavy curls that quickly fell out. Due to how uncomfortable they were to just wear for two hours, I decided to skip the trial by wearing them overnight. I didn't expect much, as I do have very thick coarse hair. May not be the product your looking for if you also have course or very thick hair.
