For anyone who uses aloe vera juice (as opposed to the gel) on hair or scalp, what sort of dilution do you use?

Thanks very much.

Based in the UK. 2-something (2b?) hair. Very porous, fine and brittle/fragile

Hair loves: Drip drying, glycerine, shea butter, oils
Hair hates: Plopping, any kind of gel, most conditioners (scalp issues).
