I know this is not at all a popular opinion, and I'm reluctant to say it even here on hexbear. But daily showering really is overrated. It can also be bad for your skin microbiome, especially if you use soap with antibacterial properties.

Also hair that goes unwashed for good lengths of time will always be healthier hair than frequently-washed hair, even if it's with the most expensive bourgsie ass shit shampoo at the salon. Just as an example, you know all those shampoo ads for dealing with split ends? Yeah, just don't use the shampoo/conditioner at all, letting your natural hair oils build up, conditioning your hair and your "split ends" will be gone or at least markedly better than they would be with any overpriced garbage hair product that promises to cure them.
