Cosmetics Formulation Development

Feel free to ask questions about the recipe. A little hairspray

I came up with the recipe. It's a hair care spray - reduce hair loss as well. I would like to know if this formula can be mixed together?

Formula 1

- Rosemary Water 60%

- Olive Oil water ( Olive Oil PEG-7 Esters) 4%

-Pure-Melatonin 2%

- Mix with the remaining 34% water.

Is this formula good enough? secretly worried about the smell Please recommend. Thank you very much
