Function of Beauty Straight Hair Shampoo & Conditioner Set — 11 oz Duo, Sulfate-Free Hydrating & Anti‑Frizz for Oily Straight Hair

Function of Beauty Straight Hair Shampoo & Conditioner is a sulfate-free shampoo and lightweight conditioner duo formulated to hydrate, smooth, and reduce frizz for naturally straight (type 1) hair.

This custom-designed two-step set pairs a hydrating coconut water shampoo with an avocado oil conditioner to refresh straight hair without weighing it down. Each bottle holds 11 oz, and the formulas are vegan, cruelty-free, and free from sulfates and parabens. The signature Nude Peach scent blends peach nectar, zesty lemon, and jasmine for a pleasant shower experience while you cleanse and condition.

How does this set keep straight hair sleek without heaviness?

The shampoo uses coconut water to deliver light hydration and gentle cleansing that removes excess oil without stripping natural moisture. The conditioner contains avocado oil to smooth the hair cuticle and lock in shine without making fine strands limp.

• Shampoo: lightweight coconut water base for moisture without buildup
• Conditioner: avocado oil to seal and enhance shine
• Sulfate-free surfactants for milder cleansing
• Formulated specifically for type 1 straight hair textures

Will this help control frizz on humid days?

The routine helps reduce frizz by smoothing the hair surface and providing consistent hydration, which decreases the hair’s tendency to swell in humidity. While not an anti-frizz medication, it improves manageability so styling tools and serums work more effectively.

• Cuticle-smoothing ingredients for reduced flyaways
• Hydration balance prevents over-dryness that causes frizz
• Layerable with styling anti-frizz products for stronger results
• Lightweight finish avoids greasy residue that attracts humidity

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

Start by wetting hair thoroughly, apply shampoo to the scalp and massage to lift oils, then rinse. Follow with conditioner focusing on mid-lengths to ends; leave for a minute before rinsing. For targeted needs, add up to three separately sold Hair Goal Boosters into your conditioner.

• Shampoo: massage into scalp, rinse fully
• Conditioner: apply mid-length to ends, leave briefly, then rinse
• Add boosters for extra hydration, volume, or color protection
• Use regularly for consistent smoothness and shine

Is this set safe for colored or chemically treated straight hair?

The sulfate-free formula is gentler than traditional shampoos and suitable for many color-treated or lightly processed straight hair routines. It helps maintain moisture and shine without harsh detergents, but for specific chemical treatments consult your stylist for compatibility.

• Sulfate-free to reduce color stripping
• Designed to preserve moisture and improve shine
• Compatible with many color care regimens; check with a pro for perms/relaxers
• Pair with color-safe boosters for extra protection

Who is this for: This shampoo and conditioner set is aimed at people with naturally straight (type 1) hair who want a lightweight, hydrating daily routine that smooths, increases shine, and tames frizz without heavy buildup. It’s suited to fine-to-medium straight strands, those with oily roots who need gentle cleansing, and anyone seeking a cruelty-free, sulfate- and paraben-free option with a pleasant Nude Peach fragrance.
