For individuals with fine and thin hair, finding the right shampoo can be a game-changer. Nexxus Thickening Shampoo aims to address this need with a specialized formula. This review delves into the key ingredients of this shampoo, evaluating their potential benefits and drawbacks.
At the heart of Nexxus Thickening Shampoo lies its ProteinFusion blend, a combination of biotin, keratin, and collagen amino acids. This blend is designed to address the specific needs of fine hair, which contains significantly less protein than thick hair and is more susceptible to breakage.
Biotin: Also known as Vitamin H, biotin is a popular supplement for promoting stronger nails and hair. While its effectiveness as a topical ingredient is debated, manufacturers claim it can smooth the skin and strengthen hair.
Keratin: Advanced Keratin Protein is included in the ProteinFusion blend to deliver stronger, fuller, thicker-looking hair.
Collagen Amino Acids: Amino acids, the building blocks of proteins like collagen, are important natural moisturizing factors (NMFs) found in the skin. They help the epidermis retain moisture, enhancing suppleness and flexibility. When collagen is broken down, it results in an amino acid mixture. These amino acids can penetrate the upper layer of the skin, aiding in moisture retention.

The shampoo utilizes a blend of cleansing agents and surfactants to effectively remove dirt and oil from the hair and scalp.
Water (H2O): The most abundant ingredient, purified and deionized water serves as the primary solvent for the other components.
Cocamidopropyl Betaine: A mild surfactant derived from coconuts, cocamidopropyl betaine is known for its foaming and stabilizing properties. It is often used in conjunction with other cleansing agents to reduce irritation and is biodegradable.
Sodium Chloride: Commonly known as salt, sodium chloride acts as a thickener in cleansing formulas containing ionic surfactants like Sodium Laureth Sulfate. It helps transform a runny solution into a gel-like consistency.
To counteract the potential drying effects of cleansing agents, the shampoo incorporates emollients and moisturizers.

Glycerin: As a humectant, glycerin helps the skin and hair retain moisture.
Apricot Kernel Oil: An emollient plant oil.
Several other ingredients contribute to the shampoo's overall performance and stability.
Gluconolactone: The neutralized form of gluconic acid, gluconolactone acts as a chelating agent, neutralizing metal ions to prevent discoloration and rancidity. It also functions as a pH regulator and humectant.
Citric Acid: Derived from citrus fruits, citric acid is an AHA (alpha hydroxy acid).

Distearyl Glycol: A diester that functions as an opacifier and pearling agent, giving the shampoo a white and glossy appearance.
Preservative: A helper ingredient that helps to make the products stay nice longer.
The shampoo contains several fragrance ingredients, which may pose a risk to individuals with sensitive skin.
Fragrance: A mixture of aromatic compounds added to impart a pleasant scent. However, the exact composition of fragrance blends is often undisclosed, making it difficult to identify potential allergens.
Citronellol: A fragrance ingredient with a rose-like odor, commonly found in geranium and rose oil. Citronellol is a known allergen and should be avoided by individuals with perfume allergies.
Eugenol: A fragrance with a spicy scent, found in clove, basil, and cinnamon oil. Eugenol has demonstrated cytotoxicity in in-vitro studies and is listed as an allergen in the EU.
Geraniol: A common fragrance ingredient that can oxidize upon air exposure, becoming allergenic.
Limonene: A fragrance ingredient found in citrus peel oils, rosemary, and lavender. Limonene can oxidize upon air exposure and cause allergic contact dermatitis. It may also enhance the penetration of other ingredients.
Linalool: A common fragrance ingredient found in lavender, ylang-ylang, bergamot, and jasmine. Like limonene and geraniol, linalool can oxidize upon air exposure and become allergenic.
Nexxus Thickening Shampoo claims to cater to fine hair, addressing its proneness to breakage and lack of protein. Environmental factors and repeated heat styling can cause damaging cracks to the outer layer of the hair cuticle, which allows excess moisture to penetrate and swell the strands, causing frizz. The formula aims to strengthen and fortify the hair, resulting in a thicker, fuller appearance.
Nexxus offers a variety of product lines, each with a unique ProteinFusion blend designed to address specific hair concerns:
Therappe and Humectress: Infused with green caviar and elastin protein, this line provides deep hydration and restores nutrients to dry hair, fortifying the surface and locking in moisture for 24 hours.
Color Assure: Designed for colored hair, this line replenishes essential natural proteins lost during the coloring process, offering color protection and keeping colored hair vibrant for up to 40 washes. It uses a ProteinFusion blend of quinoa and elastin protein, naturally rich in cysteine, glutamic acid, and serine.
Frizz Defy: Containing almond protein and jasmine flower, this blend gently moisturizes from within to strengthen hair and repel outside moisture, resulting in smooth, sleek strands.
Ultimate Moisture: Enriched with elastin proteins and marine minerals, this range detoxifies hair and scalp, restores balance, and promotes a luxurious, shiny, healthy look.
Blonde Assure: This line uses keratin protein and violet pigments to correct brassy tones and enrich bleached, platinum, or silver hair.
