After one week my hair is greasy and has dry ends

Hi there.

I started the no poo method last week (Monday) and have now been doing water only for about 7 days. I have used water and baking soda once, but didn’t seem to do a difference at all. Then I have also used conditioner in my ends once. My hair still seems to be so greasy and really dry at the ends.
It is really disencouraging me, and my hair looks almost wet all day long.

Anyone who can tell me that it gets better, or give me tips on what I could do?

I put my hair in a ponytail or in a knot everyday. But still doesn’t look too nice…
They say that even after 7 days you should see a difference but I don’t…
