I love Vatika and Ramtirth hair oils. I avoid anything mineral oil based so I do read labels. It's all about that coconut oil baby!
As for powders, shikakai is essential for my washes and I add brahmi, amla, and neem (all by Hesh). If I can find it, I use Godrej Nupur with henna, brahmi, amla, and bhringraj. I don't really get color from henna because I never use it straight, I don't leave it on very long and I do not add acids, etc. to boost the colorant properties.
Have fun with Indian hair care. I have found it works well for me and I am slowly hooking my family!
