Shampoo Formulation for Hair Loss/Dandruff and Dog Skin Spray Formulation with Oils

Hello, regarding your questions and the staff's recommendations, here is a summary and further advice:

For the revised shampoo formula (focused on hair loss and dandruff, targeting pH 5.5) with the ingredients and percentages you provided:

• Sulfate Free Shampoo Base (pH 7, Clear, Foaming) 30 %
• Dandruff-Guard™ 1 %
• Biotin Express™ 1.5 %
• Panthenol (Vitamin B5) ExtraLite™ 0.5 %
• Hydrolyzed Silk Protein (Sericin, Powder) 0.5%
• Bergamot Essential Oil 1 %
• Phenoxyethanol SA (Optiphen Plus) 1%
• Water 44.5 %

This formula contains ingredients aimed at reducing dandruff (Dandruff-Guard™) and nourishing hair/scalp to reduce hair loss (Biotin Express™, Panthenol, Hydrolyzed Silk Protein), which aligns with your second original goal.

Points to consider for this shampoo formula:

1. pH Level: The shampoo base you chose has a pH of 7. If you are targeting a pH of 5.5 for this formula, you will need to adjust the pH downwards using an acidifier like Lactic Acid or Citric Acid.
2. Efficacy of Actives: As the staff recommended, many active ingredients like Biotin Express™, Panthenol, and Hydrolyzed Silk Protein are significantly more effective in a leave-on format (like a spray or serum) as they require time to penetrate the scalp and hair. Including them in a wash-off product like shampoo means they are rinsed away quickly, resulting in lower expected efficacy. However, if you still wish to include them in a shampoo, the percentages you listed are reasonable starting points. The main limitation is the efficacy of these actives in a wash-off product.

Regarding your question about making a skin spray for dogs (first formula, pH 7.5) using your initially listed ingredients (Borage Oil, Babassu Oil, Bisabolol, Avena sativa (Oat) Oil, Shea Butter, Natural Moisturizing Amino Acids, Nano Silver Pure™) to reduce inflammation/rashes, itching, and nourish the skin, while being easily absorbed and non-sticky:

• Several ingredients you wish to use are oils (Borage Oil, Babassu Oil, Oat Oil, Shea Butter), which are not directly soluble in water.
• To create a spray that is easily absorbed, non-sticky, and can combine these oils with water-soluble ingredients (Bisabolol, Amino Acids, Nano Silver), you will need a sprayable emulsion base or a suitable emulsifier system to effectively disperse the oils in water as a lightweight emulsion.
• Using Ethyl Alcohol as a base, as suggested in the staff's sample spray (which was geared towards hair/scalp), might help with quick drying, but a high oil content could still feel sticky and might not be ideal for sensitive dog skin.
• Therefore, if you want a skin spray for dogs that is easily absorbed and contains oils, we recommend looking for a milky spray base or a lightweight lotion base that can be sprayed, or choosing emulsifiers that create a light texture to combine the oils with water.

Regarding the question about masking Borage Oil smell with Citromask and using it with Essential Oils, the staff has already confirmed that Citromask helps reduce the odor and can be used with Essential Oils, although it might slightly suppress the Essential Oil scent.

In summary, the shampoo formula you revised can be used for hair loss and dandruff (with potential pH adjustment), but the efficacy of some actives might be limited in a wash-off product. For the dog skin spray containing oils, a sprayable emulsion base is needed for a non-sticky, easily absorbed texture.
