Yes, as long as you aren't oily and don't use styling product

As long as you don't have really oily hair then that's the recommended amount, washing it more than that can strip your hair of natural oils and that would make your hair even more fragile.

yes, as long as you think it looks ok (aka, doesnt get too oily or whatever), its actually good to not overwash fine thin hair because it overdries your scalp and makes your hair even weaker to wash it a lot :)

It's more than enough. I have an oily hair and wash it 2 times a week. It is getting better now - not so oily any more. The more you wash your hair the worst it will get. The hair need the oil that is producing, so even if you stay one day with dirty hair, believe me it is worth it. It will take time but you will see a difference. Keep washing it no more than twice .....

The recommendation for healthy hair is that you wash hair but shampoo less often. (maybe twice a week if you can)

The reason being is so that hair isn't always stripped of natural oils that is produced.

And yes there is a thing as hair being "too clean" as odd as it may seem.
