Shampoo Formulation for Oily Hair, Dandruff, and Hair Loss

Subject: Shampoo Formulation for Very Oily Hair

Thank you for providing the list of ingredients for your shampoo formulation. Based on the ingredients you listed, this formula has the potential to address very oily hair, dandruff, and bacterial issues, and help with the appearance of hair loss/flatness through conditioning.

Here's a breakdown of how some ingredients relate to your concerns:

• For Oily Hair & Cleansing: The formulation contains several surfactants (Plantacare 2000, Coco Glucoside, Sodium Lauroamphoacetate, Potassium Cocoyl Glycinate, Potassium Cocoate, Sodium Cocosulfate). This blend is designed to cleanse the scalp and hair. Zinc PCA is a key ingredient known for its ability to help control sebum production. Traditional Thai extracts like Bai Mee, Makham Di Khwai (Soap Nut), and Makrut (Kaffir Lime) are also included, which are traditionally used for their cleansing and scalp-balancing properties.
• For Dandruff & Bacteria: Zinc PCA has anti-bacterial and anti-inflammatory properties, making it effective against dandruff and scalp issues related to bacteria. The herbal extracts may also contribute to a healthy scalp environment.
• For Hair Loss & Flatness: Ingredients like Hydrolyzed Vegetable Protein and Guar Hydroxypropyltrimonium Chloride (GuarCat) provide conditioning and can help strengthen hair and add volume, making hair appear less flat. Panthenol (Vitamin B5) and Aloe Vera Extract offer moisturizing and soothing benefits to the scalp and hair. Biotin is often associated with hair health, but its effectiveness in topical applications for hair growth is less established. The formula addresses the appearance of flatness through conditioning but may not directly treat the underlying cause of hair loss.

Regarding "100% Natural":

It's important to note that while your list includes many natural extracts and naturally-derived ingredients, some ingredients like Sodium Lauroamphoacetate, Guar Hydroxypropyltrimonium Chloride (GuarCat), Zinc PCA, Panthenol (Vitamin B5), and the preservative blend (Ethylhexylglycerin Caprylyl Glycol) are typically synthetic or chemically modified natural ingredients. Achieving a strictly 100% natural formulation with the same level of performance (especially in terms of cleansing efficacy, conditioning feel, and preservation) might require substituting some of these ingredients with alternatives like purely plant-derived surfactants (e.g., saponins from Soap Nut), natural conditioning agents (though cationic feel is hard to replicate naturally), and natural preservative systems.

Suggestions for Adjustment:

• To enhance oil control and anti-dandruff: Ensure sufficient levels of Zinc PCA and the traditional herbal extracts (สารสกัดใบหมี่, สารสกัดมะคำดีควาย, สารสกัดมะกรูด). The balance of surfactants is also crucial – effective cleansing is needed, but avoid over-drying the scalp, which can sometimes worsen oil production.
• To address hair loss: While the current ingredients support hair health and appearance, addressing the root cause of hair loss might require specific active ingredients depending on the type of hair loss. The current formula focuses more on scalp health and hair conditioning.
• For a stricter 100% Natural formula: You would need to replace the non-natural ingredients mentioned above. This would involve selecting alternative natural surfactants, finding natural conditioning alternatives (which might offer a different feel than GuarCat), using natural oil/dandruff control agents (like specific essential oils or natural acids), and implementing a fully natural preservation system.

Regarding Percentages:

Providing exact percentages for each ingredient is complex without knowing the desired final product properties (viscosity, foam, clarity, target performance) and requires formulation expertise and testing. The optimal percentage for each ingredient depends on the overall formula composition and the specific raw material used (concentration, purity, etc.). Typical surfactant levels in shampoos range from 10-20% total, conditioning agents vary, and active ingredients like Zinc PCA are used at specific recommended levels (often 0.2-1%). Natural extracts also have recommended usage rates. It is best to start with a base formulation structure and adjust ingredient levels based on performance testing.

This formulation provides a good starting point with many beneficial ingredients for oily scalp concerns. Adjustments would depend on whether the priority is maximum performance for oily hair/dandruff or adhering strictly to a 100% natural definition.
