Salons with hair washing “seats” near lower Sukhumvit, Langsuan or Silom

I just had a surgery and since then I have had difficulty lying flat (doc says it will take some time). However, I am in desperate need of a hair wash and blow dry (my hair is very long and I just cannot do it myself at this point).
Most salons in Bangkok that I have visited have hair wash “beds” where you lie down and the hairdresser washes your hair. Are there any salons that have hair wash chairs? I might have seen one many years ago but for the life of me I cannot remember.

Any suggestions around lower Sukhumvit/Langsuan or Silom would be helpful. Thank you!
