I am strongly considering using henna and indigo to get the jet black hair I've always loved. Because I will be ordering my henna and indigo online (and can't run back to the store if I need more), I am wondering how many grams most people use. I am pretty darn close to APL and my hair is fine with low-medium density. I was thinking of getting 200 grams of each.
SN: Does anyone mix their henna with OJ? I was thinking of doing that instead of lemon juice. I don't have green tea and don't plan to buy it for this purpose.
I henna for a brunette tone. So I mix the henna and the indigo together (100 grams each). Well, I mix the henna and let it release the dye (after several hours) then I mix the indigo and add it to the henna. That gives me 200g of stuff all mixed together. My hair is SL and this is the perfect amount but it depends on how thick a head of hair you have (mine isn't).
If you want jet black, you henna first, rinse it out and then you indigo the hennaed hair and rinse it out. So I would think in this instance, 100g packets of each wouldn't cut it because I needed 200g to cover my hair so I would have to get 200g of henna and 200g of indigo. (So it seems like you are on the right track with the quantities).
If I were you, I would buy the 300g but only mix 200g and have the rest on hand in the event that you needed more, you could always do it another time. You will need it to touch up your roots down the road anyway and it keeps for a good long time.
Yes, I use OJ. That's it. I don't add any other stuff. I used to use ACV but the smell makes me hurl and I can still smell it days later even after shampooing so I switched to lemon juice and that was too harsh and now I use OJ with no issues. HTH.
I do not know what brand you are using but I order mine from mehandi.com and it is very pure in content, has no "debris" in it and definitely fresher than the stuff you get off the shelf in the stores. I use the Ancient Sunrise Celebration kits to cover gray. Here is a link for them:

This is my first try at Ancient Sunrise, I usually ordered their Jamila or Yemen but those make gray hair look right silly. Hope you have a pleasant experience.
ETA: I'm not inferring that you have any gray hair
I can't see any in the pic.
