Function of Beauty Curly Hair Mask — Sulfate-Free Deep Conditioner for Natural Curls, Nude Peach 6.5 oz

Function of Beauty Curly Hair Mask is a sulfate-free, deep conditioning treatment formulated with coconut oil and shea butter to hydrate, enhance curl definition, and add bounce to natural curls.

This 6.5 oz hair mask targets dry, frizzy, or dull curly hair with an intensely moisturizing formula that layers into your routine after shampooing and conditioning. Designed by Function of Beauty’s hair specialists, the mask focuses on replenishing softness and elasticity without heavy residues, and comes scented in the brand’s Nude Peach fragrance for a subtle, spa-like finish.

How will this mask improve my curl definition and manageability?

The mask restores moisture to individual strands to reshape and accentuate natural curl patterns, helping coils and ringlets spring back with less frizz. Proteins and emollients smooth the hair cuticle so curls separate more cleanly and styling requires less manipulation.

• Deep-conditioning emollients like coconut oil and shea butter penetrate strands for improved elasticity.
• Sulfate-free formula avoids stripping natural oils that define curl structure.
• Softening agents reduce frizz and make detangling easier after rinsing.

When and how should I use the product for best results?

Apply after shampooing and your regular conditioner — coat damp hair from mid-lengths to ends, and leave on for 3–5 minutes for a quick boost or longer for more intensive treatment. Rinse thoroughly, then style as usual; using the mask 1–2 times weekly balances moisture without weighing curls down.

• Use on clean, towel-dried hair for even absorption.
• Leave under a shower cap for extra penetration on very dry curls.
• Reduce frequency if hair feels heavy; increase if strands remain dry between washes.

Is this product safe for color-treated or chemically processed curly hair?

The sulfate-free, paraben-free formula is formulated to be gentle on color-treated and chemically processed curls by prioritizing moisture and minimizing harsh cleansers. While designed with clean-beauty standards, always perform a patch or strand test to ensure compatibility with specific treatments.

• Free from sulfates and parabens to preserve color and reduce fading.
• Vegan and cruelty-free, aligning with gentler styling routines.
• If you have a recent chemical service, consult your stylist before first use.

What does the Nude Peach scent add to the experience?

The functional fragrance blends peach nectar, lemon zest, and jasmine for a bright, refreshing shower scent that lingers lightly after rinsing. It’s designed to complement the treatment without overpowering, creating a pleasant ritual that pairs with the product’s hydrating benefits.

• Top notes of zesty lemon add a fresh, clean impression.
• Peach nectar brings a soft, fruity warmth to the formula.
• Delicate jasmine rounds the scent for a subtle, spa-like finish.

Who is this for: Function of Beauty Curly Hair Mask is made for anyone with wavy-to-coily hair seeking overnight or in-shower hydration that improves bounce and curl separation. It works well for natural curls, color-treated curls, and anyone wanting to reduce frizz and increase softness without heavy silicones or sulfates. If you prioritize clean-beauty formulations and a pleasant scent while aiming for more defined, manageable curls, this mask is a targeted add-on to your weekly hair routine.
