Goodfellow & Co Moroccan Mint & Cedar Shampoo

A clarifying yet balanced sulfate-free shampoo that utilizes a strong primary surfactant softened by mild co-surfactants and soothing botanical extracts to deliver a deep cleanse without weighing hair down.

Performance Rating: 8.2

The formula features a highly effective surfactant blend led by sodium c14-16 olefin sulfonate, which provides deep cleansing and robust lather. To prevent this strong cleanser from stripping the hair, it is balanced with milder co-surfactants like cocamidopropyl betaine, decyl glucoside, and disodium cocoamphodiacetate. Conditioning and hydration are well-supported by glycerin (a humectant that retains moisture) and guar hydroxypropyltrimonium chloride, which offers excellent slip, detangling, and anti-static benefits. Additionally, humulus lupulus (hops) extract helps condition and add volume, while sodium chloride acts as an effective viscosity builder for a rich product texture.

Safety Rating: 8.7

This product earns a strong safety profile by completely avoiding harsh sulfates (like SLS/SLES) and utilizing a gentle, eco-friendly preservative system consisting of gluconolactone and sodium benzoate. The chosen surfactants are generally well-tolerated, though sodium c14-16 olefin sulfonate can occasionally be slightly drying or irritating to highly sensitive skin if not thoroughly rinsed. The main safety drawback is the inclusion of generic fragrance, which represents a potential source of contact allergens or irritation for those with highly sensitive scalps.

Final Rating: 8.4

With an overall rating of 8.4/10, this shampoo successfully bridges the gap between efficacy and safety. It delivers reliable, professional-grade cleansing and conditioning through its thoughtful combination of surfactants, polymers, and humectants. Simultaneously, it maintains a clean profile by opting for safe, modern preservatives and milder cleansing alternatives, making it an excellent choice for most hair types, barring those with extreme sensitivities to fragrance.

Verdict

This shampoo offers an excellent middle ground for those seeking a thorough, deep cleanse without the use of traditional sulfates like SLS or SLES. The formulation relies on sodium c14-16 olefin sulfonate as its primary cleansing agent. While technically sulfate-free, this surfactant is powerful and highly effective at stripping away excess sebum, stubborn dirt, and heavy styling product buildup. To prevent this strong cleanser from over-drying the hair and scalp, the formula is thoughtfully balanced with incredibly gentle co-surfactants, including cocamidopropyl betaine, decyl glucoside, and disodium cocoamphodiacetate. This multi-surfactant blend ensures a rich, satisfying lather while significantly mitigating the potential for irritation. Hydration and conditioning are addressed through a few key ingredients. Glycerin acts as a classic humectant, drawing moisture into the hair and scalp, while guar hydroxypropyltrimonium chloride provides lightweight conditioning. This cationic polymer helps with detangling, reducing static, and smoothing the hair cuticle without leaving a heavy, greasy residue that could weigh down finer hair types. A standout aspect of this formulation is its focus on scalp health. It includes gluconolactone, a gentle polyhydroxy acid (PHA) that provides mild exfoliation to help clear dead skin cells from the scalp while acting as an extra humectant. Furthermore, humulus lupulus (hops) extract is incorporated for its natural soothing, anti-inflammatory, and antimicrobial properties, which can help calm irritated scalps and add natural shine and volume to the hair. The preservative system is also remarkably mild, utilizing sodium benzoate and gluconolactone instead of harsher alternatives. In conclusion, this is a highly functional, well-designed shampoo. It is particularly brilliant for individuals who struggle with oily scalps, fine hair, or frequent product buildup, offering a refreshing cleanse that leaves the scalp feeling pristine. However, because sodium c14-16 olefin sulfonate can still behave aggressively on fragile hair, those with extremely dry, damaged, or highly coiled hair textures should proceed with caution. For these hair types, it is best utilized as an occasional clarifying treatment rather than a daily staple.
