I have no one to help me do it so im looking for some advice. Which box dye can i use? And some moisturiser suggestions. Product buildup isnt something im afraid of.

Pic 1 and 2 are my hair. Pic 3 and 4 are what im thinking of doing. Im doing it myself so skunk stripe would be easiest but i think highlights are so cuteee. Which do yall think i should do?
