Pravana Hair Color I'm About To Color My Hair Myself For The First Time And I Need Help! (questions About Permanent Hair Color)?

I'm about to color my hair myself for the first time and i need help! (questions about permanent hair color)? - pravana hair color

I had my hair dark brown hair now I am trying to save myself for money. I just Pratima Creme Hair Color Cream, which I Pratima developers. I heard of this brand has seen a video on YouTube in Hair coloring at home. in the video said semi-permanent hair color and non-permanent hair color for the bands permanent hair color is "river" where you want to change the colors used. If you have any specific products that I had, and it seems that the products are durable, so now I'm worried and confused! can anyone tell me if this is true, because I know if I want a different hair color now need to know .... and what is the purpose of the sponsor? Thank you! I have no idea what I do, lol!
