Formula Review for Hair Loss and Growth Spray

Here is a review of your proposed formula for a hair loss and growth spray, considering your oily scalp and dry hair:

Ingredient Analysis:

• Copper Peptide (GHK-Cu): Used at 3%, which is within the recommended range. This ingredient is known for nourishing hair roots and stimulating hair growth.
• Long-Lash™: Included at 10%, the maximum recommended level for efficiency. While primarily designed for eyelash growth, its mechanism involving peptides that stimulate Keratin Genes and containing Copper Tripeptide-1 could potentially benefit scalp hair growth as well.
• Zinc PCA: At 0.3%, this is within the recommended range for hair/scalp products. As discussed in the previous conversation, Zinc PCA is beneficial for oily scalps as it helps reduce oiliness and hair loss associated with it by reducing DHT production.
• Pure Keratin™: Used at 2.0%, the recommended rate for a leave-on treatment. This ingredient is excellent for restoring and nourishing dry or damaged hair strands, making them stronger and more moisturized. It is suitable for your dry hair.
• Melatonin Forte™: Included at 1%, the recommended maximum usage rate. Melatonin is a powerful antioxidant and research suggests it can stimulate hair growth and reduce hair loss.
• Flora Solve™ Clear: Used at 5%. This is a solubilizer necessary to help incorporate oily ingredients like Melatonin Forte™ into the water-based formula. The ratio of Flora Solve™ Clear to Melatonin Forte™ (5:1) is appropriate for solubilization.

Overall Comments and Considerations:

• The combination of Copper Peptide, Long-Lash™, and Melatonin Forte™ provides a multi-targeted approach to stimulating hair growth and reducing hair loss.
• Zinc PCA is a good addition specifically for addressing your oily scalp condition, which can be a contributing factor to hair loss.
• Pure Keratin is suitable for improving the condition of your dry hair strands.
• Mixing: Ensure you follow the mixing instructions for each ingredient, particularly adding heat-sensitive ingredients like Copper Peptide, Long-Lash™, and Melatonin Forte™ in the final step below 40°C. Mix Flora Solve™ Clear with Melatonin Forte™ first before adding to the water phase.
• pH: Check the final pH of the formula. For optimal stability of the peptides and solubility of Zinc PCA, a pH in the range of 4.5-5.5 would be ideal.
• Packaging: Melatonin Forte™ is sensitive to air. Using packaging that minimizes air exposure, such as a vacuum spray bottle, is recommended to maintain its effectiveness over time.

This formula appears well-designed to address both hair loss/growth and your specific scalp/hair type concerns when prepared correctly.
