Voluminous Shampoo

The Rahua Voluminous Shampoo is a clarifying volumizing shampoo for fine to medium-thick hair that quickly loses fullness or becomes greasy faster at the roots. The balanced formula thoroughly cleanses the hair and scalp without unnecessarily drying out the lengths, giving the hair more fullness, bounce, and texture.

Green tea, lemongrass, and aloe vera help remove styling residue and excess sebum. Rahua oil, hydrolyzed quinoa, and panthenol complement the cleansing action with lightweight conditioning, leaving the hair feeling fresh, flexible, and naturally shiny. The fresh, aromatic scent of eucalyptus, lemongrass, and lavender makes every hair wash an invigorating care ritual.

• Clarifying volumizing shampoo for fine to medium-thick hair.
• Ideal for hair that quickly looks flat, lacks lift, or becomes greasy faster at the roots.

Voluminous Shampoo combines thorough cleansing with lightweight, non-weighing conditioning. Green tea contributes antioxidant plant compounds to the formula, while lemongrass, aloe vera, and plant-derived glycerin help the hair and scalp feel pleasantly balanced after washing.

Rahua oil is rich in omega-9 fatty acids and conditions the lengths, leaving them smooth. Hydrolyzed quinoa and panthenol complement the formula to keep the hair soft and conditioned without sacrificing lightness. The result is clean, airy hair with visibly more fullness and natural shine.

Rahua combines plant knowledge from the Amazon with modern, natural hair care. At its heart is valuable ungurahua oil, which Indigenous communities have used for hair care for generations. Through its Symbiotic® partnerships, the brand works with local communities and supports the protection of the Amazon rainforest.

Key Ingredients

• Capryloyl Glycine: This multifunctional ingredient supports balanced sebum production, making it particularly interesting for fine hair that becomes greasy quickly at the roots or loses volume. Capryloyl glycine also has hair-conditioning properties and supports soft, smooth, shiny hair - a beneficial combination of scalp balance and lightweight care.
• Green Tea & Lemongrass: Green tea provides catechins and other polyphenols with antioxidant properties and helps protect the hair and scalp from oxidative stress caused by external factors. Lemongrass complements the shampoo's clarifying focus and supports a fresh, lightweight feel. The combination is particularly suitable for fine to medium-thick hair that quickly looks flat or weighed down.
• Rahua Oil (Ungurahua): This omega-9-rich Amazonian oil conditions the lengths without overpowering the shampoo's clarifying focus. It helps make rough or dry areas of the hair smoother, supports natural shine, and counteracts a brittle feeling after cleansing - especially useful for fine hair that needs conditioning but is easily weighed down.
• Hydrolyzed Quinoa & Panthenol: Hydrolyzed quinoa attaches to stressed areas of the hair fiber and can improve shine as well as wet and dry combability. Panthenol additionally penetrates the hair fiber and supports its mechanical strength and elasticity. Together, both ingredients help keep fine and damaged hair smooth, more resilient, and conditioned without taking away its desired lightness.
• Aloe Vera & Glycerin: These two humectants help bind water in the hair and counteract a dry or straw-like feeling after cleansing. Aloe vera also supports a comfortable scalp feel, while glycerin maintains the smoothness of the lengths. This allows the shampoo to clarify thoroughly without unnecessarily reducing moisture and flexibility.
• Sodium C14-16 Olefin Sulfonate & Cocamidopropyl Betaine: This surfactant combination thoroughly removes excess sebum, styling residue, and buildup from the hair and scalp. Especially with fine hair, this intensive cleansing can create more lightness and lift at the roots by removing weighty residue. Cocamidopropyl betaine complements the cleansing action and supports a balanced, well-foaming cleansing complex.
• Eucalyptus, Lavender & Rosemary: These aromatic botanical ingredients shape the clear, fresh-herbal scent and complement the formula with antioxidant plant compounds. Eucalyptus provides a particularly fresh scalp sensation, while lavender and rosemary round out the botanical care profile.

Rahua Lines at a Glance

Classic - the all-rounder for all hair types
If you do not have pronounced hair or scalp concerns and are looking for balanced care. Rahua oil, quinoa, and palo santo cleanse, condition, and strengthen without unnecessarily weighing down the hair. Ideal for: normal hair and uncomplicated daily hair care.

Voluminous - for fine, thin, or quickly greasy hair
The lightest Rahua line for more fullness, texture, and volume. It cleanses thoroughly without weighing down the hair and is especially well suited when the roots become greasy quickly. Ideal for: fine to normal hair, low volume, and quickly greasy roots.

Hydration - for dry, thick, and curly hair
The most moisturizing line in the range. Mango, sacha inchi, and other plant ingredients provide intense conditioning for dry lengths, smooth frizz, and improve softness. Ideal for: dry, thick, curly, or frizz-prone hair.

Enchanted Island - for strengthening, vitamin-rich care
A versatile line for all hair types, focusing on stronger hair and intensive botanical care. A plant-based biotin complex, pomegranate, and guava support resilient, healthy-looking hair. Ideal for: all hair types, especially when strengthening and conditioning are the priorities.

Color Full - for color-treated and highlighted hair
Targeted care for colored hair. The line helps maintain color vibrancy, balance unwanted warm tones, and protect the hair from external influences. Ideal for: color-treated, tinted, or highlighted hair.

Aloe Vera - for dry, irritated scalps
Lightweight moisture and soothing scalp care with aloe vera, witch hazel, and guayusa. The line cleanses gently and is particularly pleasant when the scalp is prone to dryness, tightness, or irritation. Ideal for: dry or irritated scalps and hair that needs lightweight moisture.

Rebalance - for buildup, excess sebum, and mildly sensitive scalps
The most minimalist Rahua line: it removes buildup and excess sebum, restores balance to the scalp, and contains no added fragrance. The lightweight conditioning is also suitable for regular hair washing. Ideal for: mildly sensitive scalps that are also prone to buildup or becoming greasy quickly.

And for heavier buildup?
Scalp Exfoliating Shampoo is not a separate care line, but a more intensive addition for occasional deep cleansing. It exfoliates the scalp and is used before regular shampoo when there is heavier buildup. Rebalance, on the other hand, is the better choice if you want to clarify regularly.

In brief:
Classic = balanced all-round care · Voluminous = fine hair & volume · Hydration = dryness & frizz · Enchanted Island = strengthening & conditioning · Color Full = color-treated hair · Aloe Vera = dry, irritated scalp · Rebalance = buildup, sebum & mildly sensitive scalp
