Hair Growth Serum Formulation

I'm looking for a skilled formulator to create a hair serum that promotes hair growth. The serum should be suitable for all hair types and have a moderately thick texture.

Key ingredients to include are:
- Niacinamide
- Caffeine
- Ginger root
- Resveratrol
- Tocopherol
- Arginine

You can add, replace, or adjust any ingredients as necessary. We need effective emulsifiers and preservatives as well.

Ideal Skills and Experience:
- Experience in cosmetic formulation, particularly hair products
- Knowledge of emulsifiers and preservatives
- Understanding of the benefits of the specified ingredients
- Ability to create a serum with a moderately thick texture
