I have three questions about Ehram.
1: Is it permissible to use unscented Halal deodorant while in Ehram. Or use corn starch/ soda to keep dry.
2: Can we use regular mint toothpaste or do we need unscented toothpaste or Missam?
3: Is it true that while in Ehram we cannot use any clothing, sheets etc that is yellow in colour ?

1. Yes you are allowed
2. Unscented
3. No reference to yellow however it should not be attractive.
