help with bleached hair

ive been using the k18 leave in mask and oil for about a week now. my bleached hair is damaged and k18 helps with the split ends. it also makes my hair feel a little more smooth. my only problem is that it doesnt last. when i wake up, the bleached parts of my hair feel dry and damaged. i only shampoo when i shower, towel dry, apply the leave in mask, wait for 4 minutes then apply the k18 oil. i dont use any other products after k18 because i thought it would interfere with it. now i think that i have to.

are there any product recommendations you guys have that i can use after i apply k18?
