If you have to shower every day, try washing your hair with Conditioner only. Only use shampoo if your hair is really dirty.
And yes, use conditioner.
Make sure you use products that work out for you. If your hair looks greasy/dull for weeks on end, change products. Avoid silicones.
Also get a body soap that works for you. If your skin is itchy and dry, change soap. You can wash your asscrack with soap but don't get soap on any tender bits ( anus or penis ). DO WASH YOUR ASSHOLE AND PENIS DAILY, JUST DON'T USE SOAP. Use babywipes after shitting to clean up asshole properly. Or bidet shower.
Get a special facial soap and do use that on your whole face every day. Preferably morning and evening. Moisturize after.
Brush teeth morning and evening at the very least. Also floss in the evening.
Beard, stubble or bare. Shave accordingly but make sure that the look suits you. If you literally have no jaw, grow a beard anyway. Beard should be tidy. No need to go Hipster with it but it shouldn't look like that of a hobo either. Never only have a mustache.
Change shirt daily if you sweat a lot. If you don't, every other day. Change pants once or twice a week depending on what you've been up to. Change underwear daily, no exceptions.
Do not try to hide poor hygiene with deodorants/cologne. People can tell. Also, if you do use cologne, tiny little spritz is enough.
Wash your laundry according to their labels, except for underwear and socks that you should always wash at at least 60c/140f.
Change your bed sheets once a week. Everything that touches your skin. Wash pillows etc. once a year. Air out mattress if possible once a year as well.
