I created a formula composed of only oil. It contains some essential and carrier oils in the right proportions for hair. I am however, confused about tocopherol. I want to know:
1. which is a better antioxidant, alpha or gamma?
2. Which vitamin e oil contains the highest amount of the better antioxidant? i heard of t50 for gamma, but i'm not sure.
3. what percetange of it should i add to my formular to ensure high anti oxidant activity, and also safety.
