Function of Beauty Straight Hair Shampoo & Conditioner Duo — 11 oz Each, Sulfate-Free Lightweight Anti-Frizz

Function of Beauty Straight Hair Shampoo & Conditioner is a custom-formulated sulfate-free duo designed to smooth Type 1 hair, add natural shine, and control frizz while remaining lightweight.

Made to match straight hair needs, this 11 oz shampoo and 11 oz conditioner pair blends coconut water and avocado oil to hydrate without weighing strands down. The set is free from sulfates, parabens, and cruelty, and comes in the brand’s signature Nude Peach fragrance. Use them as your baseline straight-hair routine or personalize further with Function of Beauty Hair Goal Boosters.

How does this set keep straight hair sleek without flatness?

The formula balances moisture and slip to smooth cuticles while preserving natural volume. Coconut water provides lightweight hydration so hair remains pliable, and the conditioner’s avocado oil seals but doesn’t create heaviness.

• Shampoo: gentle cleansing that won’t strip essential oils
• Conditioner: targeted hydration to smooth and detangle
• Weight-managed emollients to avoid limp roots

Will this help reduce frizz on fine or oily straight hair?

Yes: the pairing targets frizz control through cuticle-smoothing ingredients rather than heavy silicones. Because it’s sulfate-free, the set cleanses kindly, which helps balance scalp oil without overdrying the lengths.

• Anti-frizz smoothing action from moisturizing botanicals
• Gentle surfactants to prevent scalp rebound oiliness
• Lightweight conditioning to avoid greasy buildup

What key ingredients make a difference in results?

Coconut water hydrates hair with minerals and lightweight moisture, while avocado oil helps lock in shine and manageability. The formulation relies on naturally derived components combined with lab-tested actives to improve texture and gloss.

• Coconut water: hydration without weight
• Avocado oil: seals cuticles and boosts shine
• Functional fragrance: Nude Peach for a fresh shower scent

How should I use the shampoo and conditioner for best outcomes?

Apply shampoo to a wet scalp and massage to cleanse, then rinse thoroughly. Follow with conditioner from mid-lengths to ends, leave for a minute or two, and rinse; add up to three Hair Goal Boosters for tailored benefits.

• Shampoo: focus on scalp, rinse well
• Conditioner: concentrate on lengths and ends
• Optional: mix in boosters for extra smoothing or moisture

Who is this for: the Function of Beauty Straight Hair Shampoo & Conditioner set is aimed at people with naturally straight (Type 1) hair who want smoother, shinier strands without heavy conditioners or harsh sulfates. It suits those who prefer vegan, cruelty-free formulas and enjoy a customizable routine—especially users wanting lightweight hydration, frizz management, and a fresh Nude Peach scent in their daily wash.
