That’s awesome, Alexandra — congrats on starting your own haircare line! Even though you’re a chemist, it totally makes sense to want guidance on the product development side — it’s a whole different world.
You might want to look into small cosmetic formulation labs or freelance cosmetic chemists who specialize in startups. Some even offer end-to-end services, from formula design to stability testing and packaging advice. Sites like Making Cosmetics or Formula Botanica’s consultant directory could be a good place to start.
Also, if your line expands beyond hair masks, consider developing a Shampoo For Dry Hair — that’s a niche with steady demand, and pairing it with a hydrating mask could create a really cohesive product set.
Good luck with your brand — sounds like an exciting journey ahead!
