GSWP Biotin Rosemary Onion 3-in-1 Shampoo

Hair can start to feel weighed down long before it looks dirty—oil and product buildup collect at the roots gradually, and a mild shampoo often is not enough to fully clear it. GSWP’s 3-in-1 shampoo is built around biotin, rosemary, and onion extract specifically to deal with that kind of accumulated buildup, rather than just refreshing the surface.

The formula works as a deep cleanse: it lifts oil and product residue from the scalp and hair shaft while the biotin and onion extract are left to work on the strand itself. Rosemary, a long-used botanical in scalp-focused formulas, rounds out the blend. The combined effect after rinsing is hair that feels genuinely light rather than simply damp—less weighed down at the roots, with more natural bounce through the mid-lengths and ends.

It is formulated as a 3-in-1, meaning cleansing, scalp care, and light conditioning happen in a single wash rather than requiring a separate step for each. That makes it a practical everyday shampoo rather than a specialty product you reach for occasionally, and it is designed to suit all hair types, so the same bottle works whether hair is fine, thick, curly, or straight.

Each bottle holds a net weight of 100g and is unisex, made without the high-concern chemicals that some shampoo formulas still rely on. The product is CPNP certified, meaning it has been notified through the EU’s Cosmetic Products Notification Portal, a formal registration step that most budget or unregulated formulas skip entirely.

Because the 100g bottle is unisex and formulated for every hair type, it works as a shared household bottle rather than a niche pick for one hair texture or one gender, which makes it a practical everyday shampoo to keep in rotation for the whole family.
