Hair Growth Formula Enhancement

I have an existing leave-in hair product that needs a professional eye. My main concern is performance—specifically, how well the blend actually stimulates and supports hair growth. I’d like a cosmetic chemist who can dig into the current ingredient deck, pinpoint any weak spots, then guide me on the tweaks, swaps, or concentration shifts that will make the formula work harder without compromising texture or sensory feel.

What I need from you:
• A concise written review of the present formula, highlighting how each ingredient contributes (or fails to contribute) to hair-growth performance.
• Clear, science-backed recommendations for improving efficacy—think active levels, penetration enhancers, proven botanicals or peptides, and synergistic combinations.
• A revised formula sheet showing suggested percentages, phase order, and processing notes.
• Basic in-house testing guidance to confirm improved performance (e.g., simple tensile strength, breakage, or micro-growth assays I can replicate or outsource).

Please send a detailed project proposal that outlines your approach, timeline, and any relevant past successes with growth-focused haircare. I’m ready to move quickly once I see a solid plan.
