Pass it on
Kids need their hair cut and doing a decent job whilst they wriggle around on the chair in front of you is definitely a job for the professionals. So it’s understandable that this mom didn’t want to have a go at cutting her kid’s hair herself. Not all of her decisions are justifiable, however.
Maybe scabies didn’t seem like such a big deal to her, but it’s an infectious disease! As a hairstylist, you’d have to take quite a lot of time off work if you caught it, affecting your livelihood as well as your health. Not telling the stylist about the condition is pretty selfish if you ask me.
