Hair Growth Serum for Oily Hair: Ingredient Compatibility and Alternatives

Based on the conversation regarding your hair growth serum formula for oily hair, here is a summary of the feedback and the revised formula proposed by the staff:

Initially, you proposed a formula including Melatonin Forte, Pro Vitamin B5, Matte Silica, Pure Keratin, Phenoxyethanol, Fragrance, and Distilled Water.

The staff advised removing Matte Silica because it's a powder and requires a viscous formula to prevent sedimentation, which your liquid serum likely isn't. They also suggested removing Pro Vitamin B5 and Pure Keratin as the primary goal is hair growth, not conditioning, and these ingredients might increase oiliness on oily hair.

The staff then proposed a revised formula focusing on hair growth and oil control:

• Melatonin Forte 1%
• Zinc PCA 1%
• Safe-B3 2%
• Biotin Express™ 1%
• Phenoxyethanol 1%
• Ethyl Alcohol 20%
• Flora Solve Clear 2%
• Fragrance 1%
• Distilled Water q.s.

However, you later discovered that Melatonin Forte and Zinc PCA are incompatible. The staff confirmed this incompatibility and recommended removing Zinc PCA and replacing it with another oil control ingredient, such as L-Carnitine.

Therefore, the final recommendation is to use the revised formula above, but replace Zinc PCA with a suitable alternative oil control ingredient like L-Carnitine due to the incompatibility with Melatonin Forte.

The mixing instructions provided by the staff for the formula containing Zinc PCA were:
Mix ingredients 1, 2, 3, 4, 5, and 6 into the Distilled Water. Mix ingredients 7 and 8 together. Once well combined, add the mixture of 7 and 8 to the first part. If cloudiness occurs, increase the amount of Flora Solve Clear. Please note that these instructions were given for the formula with Zinc PCA.
