can I write off hair care if I have a certain aesthetic that's required for work?

The IRS typically considers hair care expenses as personal grooming costs, which are not deductible. However, if you are in a profession where a specific hairstyle is a requirement and it is not adaptable for personal use, such as an actor required to maintain a certain look for a role, it may be deductible. The expense must be ordinary and necessary for your business, and you should be able to prove that it is not suitable for everyday personal use.
