The teacher is an idiot.

Yeah college teacher, please advise me on my hair care. Any thoughts about menstrual hygiene as well? I am very happy to discuss this.

I wonder how many kids were sitting there thinking I don't wash my hair everyday but I'm just gonna keep my head down and not say anything.

I used to either wash or condition my long curly hair every day then realised it is a massive ballache and not good for my hair. People can be very naive and ignorant. That said, when I had short hair, I did run my hands through it a lot (I have Trichotillomania - a condition where I compulsively pick hair out so my hands were on my hair all the time until I grew out a grey patch in my favourite spot). If you are not hands on with your hair all the time, it won't need washing for days.

When I'm in the city I have to wash my hair every couple of days. Otherwise, once a week is normal and fine.

What a jackass of a dumb teacher.

Twice a week, three max depending on the weather. I hope this person can file a complaint against the teacher. Totally uncalled for and offensive. SMH

File an ethics complaint with the school.

What kind of class was this? The teacher and students are clearly idiots. Washing your hair daily will turn it from dry to greesy pretty quickly and easily. If it were me, I would go to see his head of faculty or the college main office to complain. No teacher should be calling out students either directly or indirectly in front of others. How they handled this entire situation is not only inappropriate, but their comments and personal opinion on what classes as good hygiene were inaccurate. I would tell someone how you made you feel. Some people make mention that there is a lot of blame culture these days, and that's only true because more of the population than ever are educated on what's right and what's wrong and they call them out when they are indeed wrong. This teacher was wrong, and needs to be told so in the appropriate manner. You don't have to go to the faculty head or college office and make it a massive complaint. Just tell them how it made you feel and how it affected u

I washed my hair daily for years, my mom is a hairdresser and used to jokingly make fun of me because hardly anyone she knew did that. I've finally got down to 2 times a week, sometimes 3. My sister in law is also a hairdresser and washes her hair every 9-10 days. In other words, that teacher doesn't know what the hell she's talking about.

I dont know a single person in my 52yrs of life that washes their hair every single day. Sounds like another fake story.

OP, try cowash. It's a conditioning wash, not really a shampoo. It helped my out of control frizz and dryness. I use the I Am Me brand, Wal-Mart here sells it, as well as beauty sullpy stores like Sally Anne

I empathize; you know that "talk" your folks give you? My mom kinda díed before we got to that point. My aunt whom I lived with assumed I already knew: my cousin saw it as another thing to bully me over and her friends did too. It took one of my teachers calling my aunt before anyone told me about the wonders of deodorant cos I couldn't smell myself. Even now I'm self conscious about my possible body odor.

I wash my hair every two days (unless I had a day like today where it was super hot and I was all gross and sweaty after work) and less when I’m not working (weekends/holidays) I’m a teacher.

print out a bunch of articles about proper hair washing and put them on the teacher's desk, on top of reporting them

I don't wash my hair every day but did anyone caught on that OP doesn't use shampoo either? Doesn't rinse in between but doesn't use shampoo is a recipe for smelly oily hair. Yurk.

Many of my girlfriends didn't wash their hair everyday because it wasn't good for. Different hair has different requirements.

This teacher likely equates washing hair with just generally washing, and if you say you don't wash your hair daily then it MUST mean you're not showering or bathing at all. Even then, unless your career leaves you covered in dirt, human stuff, animal stuff, or grease, a daily shower isn't particularly necessary. It can wreck your skin if you can't afford the time or products required to replenish your natural skin oils from being constantly washed off.

It was suggested at one time to wash your hair every day. I think maybe the shampoo people thought it up because shampoos were coming out claiming to be safe enough to wash your hair every day. They assumed that you would also wash your hair since you shower every day. Many don't shower every day, but wash themselves to keep clean.

Good hair routine: condition every day, wash once a week, supplement Biotin and Collagen. Luscious locks of flowing hair

I'd print this whole thing out and leave it on their desk one day. I hope they feel awful for their words and behaviour!
