Does using aloe vera gel and black seed oil work with regrowing hair?

I probably talked about this before but it's a follow up. Does using aloe vera gel and black seed oil work in regrowing hair in bald spots? Here's how to use it from what I've been told.

Two table spoons of aloe vera gel and two or three table spoons of black seed oil mixed together.

You place the two table spoons of aloe vera gel in a bowl or cup, ether one, than you add the first table spoon of black seed oil in there, stir it up till it turns into what looks like yellow yogurt substance, always stir it up first with each table spoon of black seed oil, so the first one added, than stir, second one added, stir, third one and stir. You stir it up till it looks like a yellow yogurt like substance.

Than you apply it to your scalp, leave it in for two hours, than you can ether rinse it out with warm water and shampoo and condition afterwards, or wash it out with shampoo and conditioner ( ether one is your choice ) I was told it was a natural cure for hair loss. It reduces shedding, is anti dandruff, works for both men and women. Don't know how long you should do it till you see full optimal results but they say do it three times a week ( three days out of the week ) and keep doing it till you see full optimal results.

So tell me, does this method work in regrowing hair in bald spots, no matter what caused the hair loss?
