Help with keeping hair looking nice and clean for up to 3 to 4 days

Hello!

I need help seeking products that can help to make my hair look good and clean after 3 to 4 days without washing it.

I used to be the type to wash my hair everyday, but life has been so busy and being a salary woman in my business has not been a breeze. I need a quick fix in case I forget or don't have time to wash and dry my hair, sometimes it can be many days in a row (but I always wash it at least twice a week).

It is prone to getting greasy and I have a lot of hair. It's brown and otherwise healthy.

Thank you guys so much!!!!

Any other products not for hair to freshen me up are also welcomed!
