Yes, they will hurt your scalp the first 3 or more days. Some customers are quite used to that type of pain. Some are not. At your convenience, you can find hair cooler spray in any beauty supply to help you deal with the discomfort.

Please consult your physician prior to any visit to a braiding salon to avoid any inconvenience.
