Hair help!

I have thin, curly hair. Its been a journey to get it to a place I liked it (i achieved this by only washing once every week/2weeks). It was finally starting to look thicker and shinnier and then I messed up. I used clarifying shampoo probably 4-5 times before i realized i was loosing a lot of hair and the texture was changing. Believe me I know how stupid it is now, but everyone was always saying to use it for curly hair! Now I'm dealing with major dryness, thinning, dandruff, and frizziness. I've completely stripped my natural oils. If anyone has any advice for the most efficient way of getting my hair back to a healthy place your advice is greatly appreciated
