Belly and back support!!

Searching for advice! For the mamas that used a belly band/support system, what did you like and not like about that specific brand? I'm needing something the help with back straining (I'm a hairstylist and really struggle to shampoo multiple times a day) and constant Braxton Hicks! Baby boy is VERY low, has been head down for awhile, and is incredibly active. I'm also 31 weeks along but plan on working full time up until he comes. Thanks in advance!
