Best shampoo?!

Hi everybody 😊 I just had 100% human hair tape in extensions put in. I totally forgot to ask this question- what is the best shampoo and conditioner to use to ensure longevity? And how often should I wash my hair? I was thinking like 3 times a week but I’m not sure.

If anyone could lmk what shampoo and conditioner works the best for you that would be amazing.

Thank you! 🩷🩷
