Propylene glycol. 18g
Peg 75 lanolin. O.7g
Cocamidopropyl dimethylamino propionate. 0.3g

I don’t have experience making hair sprays and I’m not a professional, but I can offer you my thoughts.
The amount of glycerin and propylene glycol seems rather high at 36% combined. You might only need 1-5% or it could leave your hair feeling sticky. If you don’t want to use propylene glycol, you can try replacing it with propanediol, or just use glycerin alone.
As for the cocamidopropyl dimethylamine propionate, I wasn’t able to find much information about this ingredient, but it seems to be an amphoteric or cationic surfactant. You could just use cetrimonium or behentrimonium chloride instead, which are the surfactants I commonly see used in such leave-in hair sprays, and they are likely more effective at conditioning. Another option might be to replace it with some polyquaternium-7.

That is the synonym for disodium cocoamphodipropionate which is supplied as a 40% aqueous solution by many surfactant manufacturers including Stepan, Solvay, Colonial. It is one of the best amphoteric surfactant-hydrotropes out there. As for propylene glycol: yes it is needed here but not that much. Reduce by half. PG makes all that glycerin less sticky-tacky but does little for curl activation, the goal of this spritz. Without PG this would have too much tackiness. You also may want to consider increasing the PEG-12 dimethicone much higher, at least to 1.0%. Likewise the PEG-75 lanolin.
