how often should i use purple shampoo if i have virgin hair

hi! i plan on dyeing my virgin hair using bubble dye (mise en scene), but i'm not sure on how often i should be using purple shampoo.

for context, i have asian hair and live in a tropical country, so i wash it everyday to avoid oil buildup. my hair's pretty healthy, and i heard bubble dye was a safe approach for my hair type/if i want to keep it healthy.

i did some research, and you're apparently only supposed to use purple shampoo once or twice a week, but is that still the case for asian virgin hair + if you wash it everyday?

tyia!! 🫶🏼
