I do have a hair towel - two actually, one smooth cotton and one microfiber. Use these for styling, they don’t cause frizz and they get gunked up with conditioner and stuff so I’d not use them to dry off.

The rest of me gets one towel. As long as it has time to dry off between showers I figure it’s hygenic enough, and I wash it weekly. Husband uses two body towels but no hair towel as his hair is so very short.

If you are asking about a good and easy skincare routine - CeraVe unscented lotion is good enough for face and cheap enough for body. Wash whatever needs to be washed in the shower, dry off but not super dry, apply the CeraVe everywhere. After you get dressed in morning, a sunscreen for your face. If you have acne and/or are older, add prescription Tretinoin, apply that at night before bed.
