I found information on shampoo products and ingredients, but I could not find any specific details about a product called "Biogel Shampoo." However, I can provide general information on shampoo products and ingredients that may be helpful.

Ingredients and Materials:

• Water is a key ingredient in shampoo products.
• Detergents, also known as surfactants, are used to interact with oil and dirt in the hair, capture them, and allow them to be rinsed off.
• Foam boosters and thickeners are added to create a lather and improve the texture of the product.
• Conditioning agents, such as Pecosil SPP-50 and Catemol 360, can be used to help the user retain moisture and improve manageability.
• Other ingredients that may be used in shampoo products include Dead Sea Mineral Water, extracts of Witch-Hazel, Ginseng, Aloe Barbadensis, Gentian, Ginger, Ginkgo Biloba, Garlic, and Citric Acid.

Positive Aspects:

• Shampoo products can help to clean hair and remove dirt and oil.
• Conditioning agents can help to improve manageability and retain moisture.

Negative Aspects:

• Some shampoo products may contain harmful chemicals, such as parabens, SLS, petrochemicals, mineral oils, and synthetic colorants.
• Some shampoo products may contain plastic microbeads, which can cause damage to marine life.

Overall, when choosing a shampoo product, it is important to consider the ingredients and materials used, as well as any potential positive or negative aspects.
