New shampoo!

Looking for suggestions for new shampoo. I have never used conditioner, I use Herbal Essence’s bourbon Manila honey shampoo and have been for about a year and half now. I notice my hair always looks greasy, oily, and flat even after blow drying my hair and I’m starting to hate the way my hair looks. I use to use head and shoulders and it made my hair look more voluntary but it was giving me back and face acne.

Any suggestions would be lovely! Thank you ❤️
