I'm going to ask my boyfriend to stop his no 'poo hair care temporarily
Why do you think he should stop his hair care regimen?
I want him to smell good for a while, I may break up with him if smelly hair doesn't change
It's understandable that you would be put off by odors coming from your boyfriend. You should talk to him about his hair regimen and let him know that it is affecting your desire to be close to him. Being honest about his hygiene will help you both to move forward and focus on what is important.
Yeah, his hair smells super bad. At least, I hope its just his hair. He's kind of gross.
This should be an easy conversation for the two of you. Is there a reason he hates shampoo so much? Just try not to make him feel bad when you say something and I think it'll turn out okay.
