If you struggle with frizz, flyaways, or hair that just won't stay sleek, you've likely searched for a miracle product. Enter Moroccanoil Intense Smoothing Serum—a cult-favorite styling treatment designed to deliver glass-like smoothness without weighing hair down. In this review, we'll break down its benefits, how to apply it correctly, and why it's a must-have in your hair care routine.

Moroccanoil is renowned for its argan oil-infused formulas, and this serum is no exception. Whether you have naturally curly hair, color-treated strands, or simply live in a humid climate, this product promises to transform your hair's texture and manageability. Let's dive into what makes it so effective and how to get the most out of every drop.
What is Moroccanoil Intense Smoothing Serum?
Moroccanoil Intense Smoothing Serum is a lightweight, silicone-based styling product that coats the hair shaft to seal the cuticle, lock in moisture, and repel humidity. Unlike heavy oils that can leave hair greasy, this serum absorbs quickly and provides a weightless finish. It's formulated with argan oil, which is rich in fatty acids, antioxidants, and vitamin E—ingredients that nourish and protect hair from environmental stressors.
The serum is designed to be used on damp or dry hair as a finishing touch. It works by creating a protective barrier that smooths the hair's outer layer, reducing friction and preventing split ends. This makes it ideal for daily use, especially if you style with heat tools or live in a humid environment where frizz is a constant battle.
- Key benefits: frizz control, heat protection, added shine, and softness.
Top Benefits of Using an Anti-Frizz Serum
The primary benefit of any anti-frizz serum is, of course, frizz control. But Moroccanoil Intense Smoothing Serum goes beyond that. It also provides thermal protection up to 450°F, making it a great prep step before blow-drying or flat-ironing. The argan oil in the formula helps to repair damage over time, so your hair not only looks smoother but becomes healthier with consistent use.
Another advantage is its versatility. Whether you have straight, wavy, or curly hair, a few drops can define curls, tame flyaways, or add a sleek finish to an updo. It also helps to extend the life of your blowout by maintaining that just-styled look for days. For those with color-treated hair, the serum helps to prevent fading by shielding strands from UV rays and other environmental aggressors.
Compared to other serums on the market, Moroccanoil's formula stands out because it doesn't contain sulfates or parabens, making it safe for all hair types, including keratin-treated and color-treated hair. It's also vegan and cruelty-free, aligning with modern ethical standards.
- Provides heat protection up to 450°F.
- Suitable for all hair types, including color-treated and keratin-treated.
- Helps prevent split ends and breakage.
How to Use Moroccanoil Intense Smoothing Serum
To get the best results, application is key. Start with clean, towel-dried hair. Pump a small amount of serum—about the size of a dime for short hair, a quarter for medium, and a half-dollar for long, thick hair—into your palms. Rub your hands together to warm the product, then apply it evenly from mid-length to ends, avoiding the roots to prevent greasiness.
For those with fine hair, use even less product, as a little goes a long way. You can also apply a tiny amount to dry hair to tame flyaways or add shine before heading out. If you're using heat styling tools, apply the serum before blow-drying or flat-ironing to protect your strands from damage.
One common mistake is applying too much product. If you overdo it, your hair can look oily or weighed down. If that happens, simply wash your hands and run them through your hair to distribute the excess, or add a bit of dry shampoo to absorb any residue. With practice, you'll find the perfect amount for your hair's density and length.
- Apply on damp hair, focusing on mid-lengths and ends.
- Use a tiny amount on dry hair for a finishing touch.
- Always apply before heat styling for maximum protection.
Comparing with Other Moroccanoil Styling Products
Moroccanoil offers a range of styling products, each designed for specific needs. For example, the Moroccanoil Treatment Light is a lighter version of the original treatment oil, perfect for fine hair that needs moisture without weight. On the other hand, the Moroccanoil Treatment Mist is a sprayable version that's great for refreshing hair and adding shine on the go.
While these products are fantastic, the Intense Smoothing Serum is uniquely formulated for those who prioritize sleekness and frizz control above all. It's more concentrated than the Treatment Mist and provides a stronger hold against humidity. If you're looking for a product that doubles as a heat protectant and styling aid, this serum is your best bet.
For those with curly hair, the Curl Enhancing Shampoo paired with the serum can help define curls while keeping them smooth and frizz-free. The combination of a curl-friendly cleanser and a smoothing serum is a winning duo for achieving bouncy, defined curls without the crunch.
- Pair with a sulfate-free shampoo for best results.
- Use a small amount to avoid buildup.
Tips for Incorporating the Serum into Your Hair Care Routine
To maximize the benefits of the serum, consider your hair's needs. If you have dry or damaged hair, apply a leave-in conditioner or a hydrating mask before the serum. For example, the Restorative Hair Mask – Moroccanoil can be used once a week to deeply nourish strands, then follow up with the serum to lock in moisture and smooth the cuticle.
If you color your hair, the Rose Gold Color Depositing Mask – Moroccanoil can add a subtle tint while conditioning, and the serum will help preserve the color by protecting against fading. The key is to layer products strategically: start with the most lightweight, then build up to heavier sealants.
Remember that consistency is more important than quantity. Using a small amount daily will yield better results than using a large amount sporadically. Over time, you'll notice your hair becoming more manageable, softer, and shinier.
- Use weekly with a deep conditioning mask for extra nourishment.
- Apply to damp hair before styling to reduce drying time.
Moroccanoil Intense Smoothing Serum is a game-changer for anyone seeking smooth, frizz-free hair. Its argan oil-infused formula not only tames flyaways but also protects against heat and environmental damage. Whether you're prepping for a big event or just want to simplify your daily routine, this serum delivers visible results. Pair it with your favorite Moroccanoil shampoo and conditioner for the ultimate smooth-hair regimen.
