Decoding the Ingredients: A Deep Dive into Renpure Biotin & Collagen Thickening Shampoo

Renpure Biotin & Collagen Thickening Shampoo aims to boost hair volume, health, strength, and shine by combining biotin, collagen, and keratin. Let's break down the functions of each ingredient.

Key Ingredients and Their Roles

• Biotin (Vitamin B7/Vitamin H): Biotin is a crucial component of many enzymes within the body. It is often taken as a supplement to strengthen nails and hair. When applied topically, manufacturers claim that it can smooth the skin and strengthen the hair.
• Collagen (Hydrolyzed Collagen): Hydrolyzed collagen is the chemically broken-down version of the larger collagen protein molecule. Proteins are chains of amino acids linked by peptide bonds. Hydrolyzed collagen consists of shorter-length amino acids, or peptides, that act as water-binding agents, making the skin feel smooth and supple.
• Keratin: Pump up the volume with our formulas exclusive blend of vitamin b7 biotin, collagen and keratin that are known for being imperative to thicken, maintain and enhance your hairs volume, health, strength and shine!

Cleansing Agents and Surfactants

• Water (H2O): The most common ingredient in skincare and haircare products. The water used in cosmetics is purified and deionized to remove mineral ions.
• Cocamidopropyl Betaine: A very common ingredient in cleansing products like shampoos. It stabilizes bubbles and is mild, working well with other cleansing agents and surfactants.
• Sodium Lauroyl Sarcosinate: A soft, mild cleansing agent with an amphoteric structure, meaning it contains both positively and negatively charged parts.
• Sodium Methyl Cocoyl Taurate: A mild, biodegradable cleansing agent known for its foam-boosting abilities and mildness.
• Coco-Glucoside: A 100% vegetable-derived, biodegradable, mild cleansing agent that produces a moderate to high amount of foam.
• Decyl Glucoside: A vegetable-derived cleansing agent (from coconut or palm kernel oil and glucose) with great foaming abilities.

Oils and Extracts

• Argan Oil: Often called "liquid gold of Morocco," argan oil is derived from the kernel of the argan fruit. It contains 80% unsaturated fatty acids, mainly oleic (38-50%), linoleic (28-38%), and palmitic (10-18%). Argan oil can nourish and moisturize the skin and hair, neutralize collagen-damaging free radicals, reduce scars, and improve skin elasticity.
• Coconut Oil: Coconut oil has a unique fatty acid profile, being mostly saturated with lauric acid (about 50%) as its main component. It is a heavy-duty oil ideal for dry skin types, proven effective in treating xerosis and mild to moderate atopic dermatitis in children. It can penetrate the hair well, preventing protein loss and combing damage.
• Horse Chestnut Extract: Contains escin, which helps maintain healthy blood circulation and strengthens capillaries.

Other Functional Ingredients

• Glycerin: A pale yellow, corn-derived liquid that acts as a humectant, helping the skin retain water.
• Hydroxypropyl Methylcellulose: A cellulose-derived polymer that thickens products, forms a film on the skin or hair, and acts as a hair conditioner.

Preservatives and Stabilizers

• Citric Acid: An AHA derived from citrus fruits.
• Phenoxyethanol: An antimicrobial preservative that helps prevent product spoilage, working against bacteria, yeast, and mold.
• Diazolidinyl Urea: A formaldehyde-releasing preservative used to prevent product spoilage. While somewhat controversial, it is considered safe in concentrations of less than 0.5%.
• Iodopropynyl Butylcarbamate: A preservative effective against yeasts and molds and considered non-comedogenic. It is safe in concentrations of less than 0.1% but is acutely toxic when inhaled.
• Glycol Distearate: A helper ingredient that acts as a co-emulsifier (helping water and oil mix) and a foam stabilization agent.

Fragrance

• Fragrance: Added to cosmetic products to provide a pleasant scent. However, the specific components of a fragrance are often not disclosed, which can be problematic for individuals with sensitive skin or allergies.

Diving Deeper into Specific Ingredients

The Role of Coconut Oil in Hair and Skin

Coconut oil has gained popularity in both the health and beauty industries. Chemically, it's composed primarily of saturated fatty acids, with Lauric Acid making up about 50% of its composition. This saturated nature makes it a heavy-duty oil, ideal for dry skin.

Studies have shown that extra virgin coconut oil is as effective as mineral oil in treating xerosis (very dry skin) and more effective than mineral oil in treating mild to moderate atopic dermatitis (eczema) in children.

While coconut oil is beneficial for dry skin, its impact on acne-prone skin is debated. Lauric Acid, a key component, has shown promise against acne-causing bacteria (P. acnes), but both Lauric Acid and coconut oil have high comedogenic ratings. User experiences vary, with some reporting positive results and others experiencing blackheads and breakouts.

For hair care, coconut oil has demonstrated the ability to penetrate the hair shaft effectively, preventing protein loss and damage. It's often used as a pre- or post-wash treatment for damaged hair and split ends.

Argan Oil: More Than Just Hype?

Argan oil, often marketed as the "liquid gold of Morocco," is extracted from the kernel of the argan fruit. The oil contains approximately 80% nourishing and moisturizing unsaturated fatty acids, primarily oleic and linoleic acids, as well as palmitic acid.

These components contribute to argan oil's ability to nourish and moisturize both skin and hair. It's also claimed to neutralize collagen-damaging free radicals, reduce scars, and improve skin elasticity.

Understanding Hydrolyzed Collagen

Hydrolyzed collagen isn't true collagen but rather a mixture of peptides resulting from the breakdown of collagen. These peptides primarily function as water-binding agents, providing emollient properties that make the skin feel smooth.

Preservative Considerations

Diazolidinyl Urea, a formaldehyde-releasing preservative, has raised concerns due to its potential to release formaldehyde. However, the Cosmetic Ingredient Review (CIR) has deemed it safe for use in concentrations of less than 0.5%, as the amount of formaldehyde released is within recommended limits. Individual sensitivity to this ingredient may vary.
