Physical Glow Verdict
Matrix Professional Mega Smooth Shampoo is positioned as a robust option for those battling frizz across a variety of hair types, with a transparent, vegan, and biodegradable formula. The brand’s claims are ambitious, but without independent performance evidence, expectations should remain grounded in the manufacturer’s positioning rather than proven results.

With a formula that highlights vegan credentials and ingredient transparency, this shampoo aims to address the needs of those whose hair is difficult to manage—especially in unpredictable weather.
What Is Matrix Professional Mega Smooth Shampoo Positioned to Do?
Matrix presents its Mega Smooth Shampoo as a daily cleansing option designed specifically for all types of frizz-prone hair, including dry, damaged, curly, coarse, and chemically-treated strands. According to the manufacturer, the product is intended to provide frizz control and humidity protection, with claims of balancing fiber moisture in both high and low humidity. The brand also positions it as suitable for those seeking smoother, shinier, and more manageable hair, regardless of season or climate.
Formula and Ingredient Transparency
One of the most notable aspects of this shampoo is its fully disclosed ingredient list, which includes water, sodium C14-16 olefin sulfonate (a cleansing agent), cocamide MEA, glycerin, and cocamidopropyl betaine, among others. The formula features jojoba seed oil and oleic acid—ingredients the brand claims help lock out humidity and restore essential moisture, respectively. The inclusion of salicylic acid, vanillin, and citrus limon peel oil adds further complexity. Matrix also emphasizes that this is a vegan formula, containing no animal-derived ingredients or by-products, and asserts that 96% of the formula is biodegradable according to OECD 301 or equivalent tests.
Manufacturer Claims and Positioning
Matrix makes a series of ambitious claims about Mega Smooth Shampoo, stating it provides frizz control, 12 times more smoothness, and vibrant shine. The brand also describes the formula as 'supercharged' and now suitable for all hair types. While these statements set high expectations, it is important to note that they are manufacturer claims and not independently verified by third-party evidence in the supplied data.
Suitability and Practical Use
The shampoo is positioned for a broad spectrum of hair types that struggle with frizz, including chemically-treated, dry, damaged, curly, coarse, and rebellious hair. The usage directions are straightforward: apply a quarter-size amount, lather, and rinse. Matrix suggests following with their Mega Sleek Smoothing Conditioner and other products in the range for optimal results. For those interested in ingredient-conscious beauty, the vegan and biodegradable aspects may be particularly appealing.
Limitations and What’s Not Established
While the manufacturer provides a comprehensive ingredient list and makes strong claims about frizz control and smoothness, there is no independent performance data or third-party testing supplied.
