This is a clarifying, scalp-soothing shampoo formulated with colloidal oatmeal and apple cider vinegar to deeply cleanse the hair, remove stubborn buildup, and restore a healthy, natural shine.
The formula is highly effective due to Colloidal Oatmeal Extract as the primary ingredient, which deeply soothes and moisturizes the scalp. Active surfactants like Sodium C14-16 Olefin Sulfonate and Cocamidopropyl Betaine deliver strong cleansing and lathering power. Vinegar (Acetum) is included to clarify the hair and restore natural shine, while conditioning polymers such as Polyquaternium-22, PEG-7 Amodimethicone, and Polyquaternium-39 provide excellent detangling, frizz control, and smooth texture.
The safety profile is solid but has a few watchouts. Sodium C14-16 Olefin Sulfonate can be slightly drying for sensitive scalps, and Cocamidopropyl Betaine is a known potential allergen. The inclusion of Fragrance (Parfum) and glycols like Propylene Glycol may cause mild irritation to sensitive skin. Additionally, ethoxylated ingredients like PEG-7 Amodimethicone and PEG-150 Pentaerythrityl Tetrastearate carry a minor risk of contamination with manufacturing byproducts, though they are generally considered safe in finished formulations.
With an overall rating of 8.0/10, this shampoo is a well-balanced choice. It delivers strong clarifying and soothing performance thanks to the oatmeal and vinegar, making it highly effective for hair health. While generally safe, the presence of fragrance, surfactants, and PEGs slightly pulls down the safety score, meaning those with highly sensitive skin or eczema should exercise caution.
This formulation represents a thoughtful approach to scalp care, successfully bridging the gap between a deeply clarifying cleanser and a scalp-soothing treatment. At the heart of the formula is colloidal oatmeal extract, which serves as the primary ingredient. Oatmeal is celebrated in skincare for its anti-inflammatory and moisturizing properties, helping to calm itchiness and protect the scalp’s moisture barrier during the washing process.
The primary cleansing power comes from Sodium C14-16 Olefin Sulfonate combined with Cocamidopropyl Betaine. Although this product is marketed as sulfate-free, consumers should note that Sodium C14-16 Olefin Sulfonate is a strong anionic surfactant. It cleanses deeply and effectively removes sebum, sweat, and styling products, but it can be drying if overused. This deep-cleansing capability is enhanced by apple cider vinegar (Acetum), which helps dissolve mineral buildup from hard water, balances the scalp’s pH, and flattens the hair cuticle to maximize natural shine and smoothness.
To prevent the hair from feeling stripped, the formula incorporates conditioning polymers like Polyquaternium-22 and Polyquaternium-39, alongside PEG-7 Amodimethicone. This modified silicone selectively deposits on damaged parts of the hair fiber to provide targeted conditioning, reduce frizz, and improve manageability without weighing down fine hair. Humectants such as propylene glycol work to bind moisture to the hair shaft, ensuring the clarifying process doesn’t leave the hair completely parched.
Despite its soothing oatmeal base, the formula is quite potent. Those with chemically treated, extremely dry, or highly porous hair may find it too stripping for daily use and should instead relegate it to a weekly clarifying ritual. Additionally, the inclusion of synthetic fragrance (Parfum) means that individuals with severe eczema or specific fragrance allergies should approach with caution.
In conclusion, this shampoo is a fantastic drugstore option for individuals dealing with dullness, oily roots, or product buildup. It delivers a high-shine, refreshed finish while utilizing colloidal oatmeal to ensure the scalp remains comfortable, hydrated, and free from irritation.
