Based on its formula, is this product safe for sensitive, acne‑prone, or dry scalps?

The shampoo contains strong surfactants (Sodium Laureth Sulfate, Cocamidopropyl Betaine) and added fragrance, which can be drying or irritating for very sensitive or acne‑prone scalps; however, the egg yolk extract may provide soothing benefits for dry hair, so users with sensitive skin should patch‑test before regular use.

What is the specific role and benefit of Egg Yolk Extract in this shampoo?

Egg Yolk Extract supplies proteins, lipids, and vitamins that help reinforce hair structure, improve elasticity, and add natural shine, making the hair feel stronger and smoother after each wash.

What is the optimal application frequency for this shampoo, and does it contain controversial chemicals?

For most hair types, using the shampoo 2–3 times per week or as needed is sufficient; the product does contain controversial ingredients such as Sodium Laureth Sulfate, synthetic colorants CI 19140 and CI 15985, and fragrance components, which some consumers prefer to avoid.

Product Insights

The Egg Shampoo by Cosmia is a 500 ml hair cleanser formulated with water, surfactants such as Sodium Laureth Sulfate and Cocamidopropyl Betaine, and an Egg Yolk Extract that aims to strengthen and add shine to hair. The formula also includes fragrance, synthetic colorants (CI 19140, CI 15985), and a variety of preservatives and polymers, placing it in the highest processing category (NOVA 4) and potentially irritating sensitive scalps or those allergic to eggs. While the product offers the classic nourishment associated with egg proteins, consumers should be aware of the presence of common allergens and synthetic additives when choosing it for regular use.

Comparative Analysis

Positioned as an egg‑protein hair‑care shampoo, it targets users seeking natural‑derived nourishment while competing with mainstream sulfate‑based brands, differentiating itself through the inclusion of egg yolk extract but relying on synthetic fragrance and colorants that place it in a higher‑processing segment.
