Function of Beauty Straight Hair Shampoo & Conditioner XL Set — 2x22 oz, Sulfate-Free Hydration & Anti-Frizz for Oily Roots

Function of Beauty Straight Hair Shampoo & Conditioner XL Set is a sulfate-free, vegan shampoo and conditioner duo formulated to smooth, hydrate, and add lightweight shine to naturally straight hair.

This XL pair contains two 22 oz bottles designed specifically for type 1 hair. The formulas combine coconut water in the shampoo for hydration without heaviness and avocado oil in the conditioner to help seal moisture and enhance natural luster. Finished with the brand’s Nude Peach scent, the set aims to reduce frizz and preserve a sleek look while staying free of sulfates, parabens, and cruelty.

How does this set keep straight hair smooth without weighing it down?

The shampoo features coconut water to hydrate strands at the surface level and gently cleanse away oil and residue without stripping. The lightweight conditioner uses avocado oil to lock in moisture and smooth the hair cuticle so strands reflect more light. Together they balance hydration with slip so hair remains sleek but not flat.

• Coconut water in the shampoo for clean, lightweight hydration
• Avocado oil in the conditioner to smooth and seal moisture
• Sulfate-free surfactants that reduce harsh stripping
• Formulated for type 1 hair’s natural fall and shine

Will this duo help control frizz and improve shine on oily roots?

Yes—the combination targets frizz primarily by smoothing the cuticle and providing moisture where needed, while the shampoo gently removes excess oils at the scalp. Because both products are formulated to be lightweight, they help avoid adding extra weight that can make oily roots look flat.

• Gentle cleansing removes buildup at the scalp
• Conditioner smooths mid-lengths and ends without overburdening roots
• Designed to maintain natural volume while reducing frizz
• Helps hair appear shinier by improving cuticle reflection

What scent and sensory experience can I expect in the shower?

The set is finished with Function of Beauty’s Nude Peach fragrance, a balanced scent profile combining peach nectar, bright lemon, and light jasmine. Expect a spa-like, fruity-floral aroma that lingers subtly on hair after rinsing. Texture-wise, the shampoo foams reliably for a clean feel while the conditioner offers smooth slip for detangling and easy distribution.

• Nude Peach fragrance notes: peach, lemon, jasmine
• Shampoo: gentle lather for thorough cleansing
• Conditioner: silky slip for quick detangling
• Leaves a soft, lingering scent without heaviness

How should I use the XL set for best results and customization?

Use the shampoo to cleanse the scalp and roots, then apply conditioner from mid-length to ends to seal moisture and smooth. For targeted concerns, Function of Beauty offers Hair Goal Boosters that can be mixed into the bottle to personalize benefits like extra hydration, volume control, or heat protection.

• Wash scalp and roots with shampoo, rinse thoroughly
• Apply conditioner mid-length to ends, leave 1–2 minutes, rinse
• Customize with up to three compatible Hair Goal Boosters (sold separately)
• XL 22 oz bottles for longer use and fewer refills

Who is this for: This set is intended for people with naturally straight (type 1) hair who want lightweight hydration, improved smoothness, and a frizz-reducing routine without sulfates or parabens. It’s especially suitable for those who prefer vegan, cruelty-free formulas and a subtle, fruit-forward scent, and for anyone seeking larger bottles for less frequent repurchasing.
