Function of Beauty The Situ-wave-tionship: A Detailed Review for Wavy Hair Lovers

If you have wavy hair, you know the struggle: one day your waves look effortless and defined, the next they fall flat or frizz up. Enter Function of Beauty's The Situ-wave-tionship, a product designed specifically for wavy hair types. This review breaks down what this product offers, how it performs, and whether it deserves a spot in your routine.

Function of Beauty has built a reputation for customizable hair care, but their specialized wavy hair line takes it a step further. The Situ-wave-tionship is marketed as a styling product that helps wavy hair hold its shape without weighing it down. We tested it alongside other favorites like the Wavy Hair Zero Gravity Styling Mousse to see how it stacks up.

What Is The Situ-wave-tionship?

The Situ-wave-tionship is a lightweight styling cream from Function of Beauty's wavy hair collection. It's formulated to enhance natural wave patterns, reduce frizz, and provide flexible hold. Unlike heavy gels or mousses, this product aims to give waves a soft, touchable finish that looks natural, not crunchy.

The name itself is playful—a nod to the sometimes complicated relationship wavy hair has with styling products. It's designed for those who want definition without stiffness, and it works on all wavy subtypes, from loose 2A waves to more defined 2C patterns.

• Key ingredients: aloe vera, glycerin, and lightweight polymers for hold without residue.
• Best for: air-drying or diffusing wavy hair for a bouncy, natural look.

How Does It Compare to Other Wavy Hair Products?

Function of Beauty offers several options for wavy hair, so it's worth understanding where The Situ-wave-tionship fits. The Wavy Hair Zero Gravity Styling Mousse is a foam-based product that adds volume and lift, perfect for fine waves. In contrast, The Situ-wave-tionship is a cream that provides more moisture and definition, making it ideal for thicker or drier wavy hair.

For daily care, pairing it with a gentle cleanser like the Straight Hair Shampoo Jumbo can help maintain scalp health, even if your waves are more on the straight side. The key is to layer products correctly: apply the cream to damp hair, then follow with mousse if you need extra hold.

• The Situ-wave-tionship: cream, moisturizing, medium hold.
• Wavy Hair Zero Gravity Styling Mousse: foam, volumizing, lightweight hold.
• Both are sulfate-free and safe for color-treated hair.

How to Use The Situ-wave-tionship for Best Results

Start with clean, damp hair. After washing with a sulfate-free shampoo and conditioner, gently towel-dry your hair so it's not dripping. Take a small amount of The Situ-wave-tionship—about a quarter-sized dollop for medium-length hair—and emulsify it between your palms. Rake it through your hair from mid-lengths to ends, then scrunch upward to encourage wave formation.

For extra definition, you can follow with a diffuser on low heat. Let your hair air-dry the rest of the way for a softer finish. Avoid touching your hair while it dries to prevent frizz. If you want more volume, layer the Wavy Hair Zero Gravity Styling Mousse underneath the cream.

• Pro tip: Use a microfiber towel to remove excess water before applying the cream—this reduces frizz and speeds up drying time.

Who Should Try The Situ-wave-tionship?

This product is best for wavy hair types that crave moisture and definition without heaviness. If your waves tend to frizz or lose shape by midday, this cream can help lock in your pattern. It's also a great option for those transitioning from heat styling to air-drying, as it provides enough hold to keep waves intact.

However, if you have very fine or oily hair, you might prefer a lighter product like the Wavy Hair Zero Gravity Styling Mousse. The cream could weigh down delicate waves if applied too liberally. Start with a small amount and adjust based on your hair's response.

• Ideal for: wavy hair types 2A-2C, especially those with dry or frizz-prone ends.
• Not ideal for: very fine or straight-leaning wavy hair that needs maximum volume.

Ingredients and Customization Options

Like all Function of Beauty products, The Situ-wave-tionship is free from sulfates, parabens, and phthalates. It features a blend of aloe vera for hydration, glycerin for moisture retention, and lightweight polymers that create a flexible film around each wave. This helps combat humidity and frizz without leaving a sticky residue.

While this product is not fully customizable like the brand's shampoo and conditioner, it is part of a cohesive wavy hair system. You can pair it with the Custom Conditioner for added moisture or the SOS Custom Repair Leave-in Treatment if your waves need extra repair from heat or chemical damage.

• Cruelty-free and vegan formula.
• Scent: light, fresh, and non-overpowering—fades quickly after application.

Final Verdict: Is The Situ-wave-tionship Worth It?

The Situ-wave-tionship delivers on its promise of soft, defined waves without the crunch. It's a versatile styling cream that works well for most wavy hair types, especially those who want a low-effort routine. The lightweight formula and pleasant texture make it easy to incorporate into daily or weekly styling.

For the price point, it competes well with other high-end wavy hair products. If you're already a fan of Function of Beauty's wavy line, this is a natural addition. If you're new to the brand, starting with a shampoo and conditioner set before adding styling products is a smart way to build your routine.

• Pros: lightweight, defines waves, reduces frizz, pleasant scent.
• Cons: may not provide enough hold for very humid climates or thick curly waves.

If you're ready to embrace your waves with a product that understands their unique needs, The Situ-wave-tionship from Function of Beauty is worth a try. Pair it with the Wavy Hair Zero Gravity Styling Mousse for extra volume, or use it solo for a natural, effortless look. Explore the full wavy hair collection to build a routine that works for you.
