How many days can you go without washing your hair?

I have thick curly hair so I can wash my hair once a week and be good. LOL if I washed my hair every other hair my hair would get dry and fall out my head... also, washing your hair everyday or every other day isn't good for your hair either way.

2 days, anything more than that will make me want to rip my scalp off

2 - 3 weeks

Max 2 days

Around 4 days in Winter and 2 days (max. 3) in Summer.

Once a week.

I have very dry, blond and curly/wavy hair. It doesn't look a lot different even on the 6th day, but my scalp starts to itch around 6, 7th day. So I have to wash it.

1 week +

i should wash my hair every other day but i normally let it go a week without washing it because i don't have the energy
