Hair & Eyebrow Growth Tonic Formulation

Here is a suggested formulation and mixing method using the ingredients you have:

Recommended Formula

Ingredient Notes

• Biotinyl-GHK: A peptide that helps accelerate hair growth and strengthens hair roots.
• Biotin Express (Liquid 10%): Biotin (Vitamin B7) is known to help accelerate hair growth and reduce shedding. Using the liquid form makes it easy to incorporate.
• Zinc PCA: Effective in reducing hair loss caused by oily scalp by helping to control oiliness and reducing DHT. It also helps strengthen hair roots. Note that Zinc PCA is an electrolyte.
• Pro Polymer: Used to create the gel texture. Because Zinc PCA is present, a slightly higher percentage of Pro Polymer (around 2%) is recommended compared to formulas without electrolytes to maintain viscosity.
• Phenoxyethanol SA: A broad-spectrum preservative to keep your product safe and stable.
• Purified Water: The main base for the tonic.

Mixing Instructions

Follow these steps carefully to ensure proper mixing, especially with Pro Polymer and Zinc PCA:

1. Prepare the Water Phase: Measure the Purified Water into a clean beaker.
2. Hydrate Pro Polymer: Slowly sprinkle the Pro Polymer powder onto the surface of the water while stirring gently. Stir slowly for 3-5 minutes to disperse. For best results and easiest dissolution, you can let it sit for several hours or overnight to fully hydrate before proceeding, then stir slowly until a smooth gel forms. Avoid high-speed blending which can damage the polymer.
3. Dissolve Zinc PCA: In a separate small container, take a small amount of Purified Water (part of the 91.7%) and dissolve the Zinc PCA powder in it. Stir until fully dissolved.
4. Add Actives: Add Biotinyl-GHK and Biotin Express (Liquid 10%) to the main gel mixture. Stir gently until evenly distributed.
5. Incorporate Zinc PCA Solution: Slowly add the dissolved Zinc PCA solution to the main gel mixture while stirring gently. Continue stirring until the mixture is uniform.
6. Add Preservative: Add Phenoxyethanol SA to the mixture. Stir gently until fully incorporated. Ensure the temperature is below 60°C.
7. Final Check: Check the pH of the final product. Zinc PCA is most effective in the pH range of 4-6, and Phenoxyethanol SA works well in 2-6. Aim for a final pH between 4.5 and 5.5 for optimal performance and stability. Adjust pH if necessary using a suitable acid (like Lactic Acid solution) or base.

Adjustments

• Ethyl Alcohol: You listed Ethyl Alcohol. While not included in this primary formulation, you can add it if desired, typically at 5-10%, replacing an equal amount of Purified Water. It can help as a solvent and provide a lighter feel, but may also be drying. If adding alcohol, mix it into the water phase before adding Pro Polymer, or add it after the gel has formed but before adding the preservative.
• Viscosity: The suggested 2.0% Pro Polymer should create a gel texture, but the exact viscosity can vary. If you prefer a thicker or thinner gel, you can adjust the Pro Polymer percentage (within the 0.5-5% range), keeping in mind the presence of Zinc PCA requires a bit more than a simple water gel.
• Adding Other Actives: Your current list provides a good foundation. Depending on specific needs, other hair growth actives could be incorporated, but this would require adjusting the base formula and ensuring compatibility.

This formulation provides a good starting point for a hair and eyebrow tonic aimed at growth and strengthening. Remember to perform a small test batch first.
