GOOD TO KNOW.

Is this product right for you?

Which hair types benefit most from the Solid Grapefruit Shampoo?

If you want your hair to feel clean and fresh but richer shampoos quickly make it feel heavy, the Grapefruit Shampoo Bar is particularly interesting.
The concentrated solid formula cleanses hair and scalp thoroughly while creating a creamy lather.
Shea Butter, Avocado Oil and Coconut Oil add selected plant-based lipids, while our exclusively developed 4-Mineral Complex forms the distinctive mineral skincare base.
The result should be hair that feels clean, smooth and pleasantly lightweight without an unnecessarily heavy coating.
The sparkling Grapefruit scent is especially suited to anyone who prefers fresh, clear citrus notes rather than heavy or sweet fragrances.
Ideal for thorough cleansing, plant-based care and a naturally lightweight finish.
How does the Grapefruit Shampoo Bar cleanse and care without weighing hair down?

Good hair care does not mean leaving more and more product behind on the hair.
The cleansing ingredients remove oil, sweat, everyday build-up and light styling residue.
At the same time, Shea Butter, Avocado Oil and Coconut Oil provide plant-based lipids that support a smoother, softer hair feel.
Our 4-Mineral Complex forms the exclusive mineral base, while Grapefruit Oil gives the shampoo its sparkling, slightly tart freshness.
Clean and cared for – without that heavy “too much product” feeling afterwards.
What makes the SOURCE LAB Grapefruit Shampoo Bar different from an ordinary solid shampoo?

For us, a solid shampoo bar is not simply liquid shampoo without a bottle. What matters is how cleansing, care and the mineral base work together.
The SOURCE LAB Grapefruit Bar combines mild cleansing, shea butter, avocado oil and coconut oil with our exclusively developed 4-mineral complex. This creates more than just another solid shampoo alternative: it is a formula with clearly defined roles — to cleanse, care for your hair and leave it feeling pleasantly light.
The bar is also handmade in East Frisia. Grapefruit oil gives it its fresh, zesty scent, while the included loofah soap pad helps the bar dry between uses so it lasts longer.
If you prefer a different scent, the SOURCE LAB solid shampoo range also lets you choose between Lemongrass and Orange.
Concentrated cleansing. Plant-based care. An exclusive mineral base. Handmade, with a character of its own.

OUR 4-MINERAL COMPLEX

More than classic sensitive care: our unique approach for moisture balance, skin barrier, and a calmer skin sensation.

Exclusive to SOURCE LAB Selected raw materials according to pharmaceutical standards Sensitive care reimagined

Sodium

MOISTURE BALANCE

Sodium is a natural component of your skin's moisture balance and is closely linked to its hydration.

Sodium

Balance starts with the basics

Sodium supports your skin's natural moisture balance. As a skin-native electrolyte, it helps distribute water between cells and their surroundings.

Calcium

BARRIER & STRUCTURE

Calcium plays an important role in the natural development of your skin barrier.

Calcium

Structure for Sensitive Skin

Calcium supports the natural maturation of skin cells. It thus plays an important role in building the protective barrier that retains moisture and fends off external influences.

Magnesium

PEACE & BALANCE

More moisture, less roughness: observed in a study with magnesium-rich brine.

Magnesium

The quiet core of the complex

Magnesium salts can bind water. A study with a magnesium-rich saline solution showed improved skin hydration and reduced roughness in dry skin.

Strontium

SKIN FEEL

Certain strontium salts were able to noticeably alleviate burning and stinging sensations induced in skin tests.

Strontium

Selected for a better skin feel

Burning and stinging are among the bothersome aspects of sensitive skin. In studies, certain strontium salts were able to noticeably alleviate both after targeted skin irritation.

The scientific classification refers to the minerals examined in each case and their specific study conditions.
