Why customers choose Auvira Beauty

Function of Beauty Straight Hair Shampoo & Conditioner XL Set is a sulfate-free, vegan shampoo and conditioner duo formulated with coconut water and avocado oil to smooth, hydrate, and enhance natural shine for straight hair.

This XL duo (22 oz each) is built for type 1 hair that needs lightweight hydration and anti-frizz control without heaviness. The pair combines a hydrating coconut-water shampoo with an avocado-oil conditioner and arrives in the brand’s customizable lineup—compatible with optional Hair Goal Boosters for tailored performance. The scent profile is Nude Peach, blending peach nectar, lemon, and jasmine notes for a refreshing shower experience.

How does this set help control frizz and keep straight hair smooth?

The formulas work together to hydrate and seal the hair cuticle so strands lie flatter and reflect light more evenly. The shampoo cleanses gently to remove excess oil and buildup while the conditioner deposits lightweight moisturizers that reduce surface friction—key for minimizing flyaways.

  • Shampoo uses coconut water to add moisture without weighing hair down.
  • Conditioner contains avocado oil to lock in hydration and enhance gloss.
  • Sulfate-free surfactants preserve natural oils to prevent rebound frizz.
  • Lightweight formulation is designed for fine to medium straight hair.

Will this XL set weigh my oily scalp down or make hair greasier?

The Straight Hair Shampoo is formulated to cleanse sebum and styling residue without stripping, while the conditioner targets mid-lengths and ends to avoid overloading the scalp. Applied correctly—shampoo to scalp, conditioner to lengths—you’ll get a balanced clean plus controlled hydration.

  • Shampoo: clarifies oily roots with gentle, sulfate-free cleansers.
  • Conditioner: apply mainly to mid-shaft and ends to prevent scalp buildup.
  • XL 22 oz sizes reduce frequency of repurchase for regular users.

How do I use these products for best results and customization options?

Use the shampoo to cleanse thoroughly, rinse, then follow with the conditioner to seal in moisture. For personalized benefits, add up to three Function of Beauty Hair Goal Boosters to your conditioner or use them separately depending on your targeted goals.

  • Wet hair, apply shampoo to scalp, lather, rinse; repeat if needed.
  • Apply conditioner to mid-lengths and ends; leave 1–3 minutes, then rinse.
  • Mix in up to three Hair Goal Boosters for extra volume, repair, or smoothness.

What ingredients power the Straight Hair duo and are they clean-beauty friendly?

The key actives are coconut water in the shampoo for lightweight hydration and avocado oil in the conditioner for sealing moisture and boosting shine. Function of Beauty maintains clean-beauty standards across the formula—vegan, sulfate-free, paraben-free, and cruelty-free—while blending naturally derived ingredients with lab-formulated performance agents.

  • Coconut water: hydrates without heaviness, supporting natural movement.
  • Avocado oil: nourishes and enhances surface gloss for a polished look.
  • Free from sulfates, parabens, and animal testing to align with modern clean standards.

Who is this for: This XL Straight Hair Shampoo & Conditioner set suits anyone with naturally straight hair seeking a lightweight, hydrating routine that tames frizz and boosts shine—especially those with oily roots who still need moisture at the lengths. It’s ideal for people who want a clean-beauty option in larger sizes and who enjoy a customizable regimen using optional boosters to dial in specific hair goals.
