Based on its formula, is this product safe for sensitive, dry, or acne-prone scalp and hair?

Yes, the gentle plant-derived surfactants (Decyl Glucoside, Cocamidopropyl Betaine, Coco Glucoside) and soothing algae extracts make it suitable for sensitive or dry scalp, though the fragrance containing benzyl alcohol and limonene may still irritate extremely sensitive users.

What is the role and benefit of Laminaria Digitata (seaweed) extract in this shampoo-shower gel?

Laminaria Digitata extract supplies minerals, vitamins and polysaccharides that help moisturize, strengthen hair fibers and soothe the skin, enhancing overall softness and resilience.

Is the formula considered cruelty-free and vegan, and what is its recommended period after opening?

With Ecocert and Cosmebio organic certification and no animal-derived ingredients, the product is marketed as cruelty-free and vegan, and it is best used within 12 months after opening.

Product Insights

Coslys Ultra-Gentle Algae Shampoo-Shower Gel is a 250 ml organic formula certified by Ecocert and Cosmebio, combining water, Spiraea Ulmaria flower extract and Laminaria digitata (seaweed) extract to gently cleanse hair and skin. The formulation avoids synthetic perfume and traditional soap, relying on mild surfactants such: Decyl Glucoside, Cocamidopropyl Betaine, Coco Glucoside and a small amount of Sodium Coco-Sulfate, while adding glycerin, sea salt, and natural extracts for hydration and soothing. Potential irritants include the added fragrance (Parfum) containing benzyl alcohol and limonene, and the presence of sodium coco-sulfate may be a concern for highly sensitive scalps, although the overall ingredient list is free from parabens and harsh sulfates.

Comparative Analysis

Positioned as an organic, ultra-gentle 2-in-1 shampoo and shower gel with algae extracts, it targets eco-conscious consumers looking for a soap-free, low-sulfate alternative to conventional hair-and-body cleansers.
