Product Details

A shampoo bar changes the everyday routine in a small but noticeable way: no bottle, no drips, and a formula concentrated enough that a single 60g bar does the work of several liquid bottles. This handmade bar from Water Ice Levin is built around three familiar names in hair care—biotin, onion extract, and rosemary—combined into a solid, travel-ready cleanser rather than a diluted liquid.

Each wash starts with a gentle lather that cleanses the scalp without over-stripping it, which matters for anyone who has felt the tight, dry sensation that harsher shampoos leave behind. Biotin and onion extract are worked into the bar to support hair from root to end, while rosemary contributes its familiar herbal character and a long history of use in scalp-focused formulas. The result is hair that feels nourished rather than merely rinsed, with less of the frizz that dry, understimulated strands tend to show.

The bar is formulated without sulfates or parabens, and it is made without nuts, soy, or gluten, which makes it a reasonable option for people who have had reactions to those common allergens in other personal care products. Because it is a solid bar rather than a bottled liquid, it also survives a gym bag, a carry-on, or a shared bathroom shelf far better—no leaks, no spills, no liquid restrictions to think about before a flight.

One 60g bar is sized to last roughly 50 to 75 washes depending on hair length and how it is stored between uses, which puts its per-wash cost well below a comparable bottle of liquid shampoo once you account for the water that bottled formulas are mostly made of. Letting the bar dry fully on a draining soap dish between washes extends that further and keeps the bar firm rather than soft and quick-dissolving.

It sits naturally alongside other handmade, botanical bar formats in our black soap collection, and pairs well with the wider range of plant-based personal care in our African natural products selection.

Why Choose Onion & Biotin Shampoo Soap – 60g

Concentrated, Not Diluted. Unlike a bottled shampoo that is mostly water, this bar concentrates biotin, onion extract, and rosemary into a solid format, so a small amount goes a long way.

Free From Common Irritants. No sulfates, no parabens, and no nuts, soy, or gluten in the formula make it a sensible choice for anyone managing sensitivities to those ingredients.

Because it is handmade in small batches, the bar’s texture and scent can vary slightly from batch to batch, which we consider a feature of a genuinely small-production formula rather than a defect.

A Practical Everyday Swap. For anyone looking to cut down on plastic bottles or simplify a travel bag, this bar replaces a full-size liquid shampoo without asking you to change your washing routine.

Onion & Biotin Shampoo Soap – 60g Benefits

Gentle Scalp Cleanse. The bar lathers into a mild, sulfate-free cleanse that lifts everyday oil and buildup without leaving the scalp feeling tight or stripped.

Nourishes Root to End. Biotin and onion extract are worked through the bar so every wash reaches hair from the root down to the ends, not just the surface.

Helps Reduce Frizz. Rosemary and the bar’s conditioning base leave strands smoother and easier to manage, which shows up as less flyaway frizz once hair dries.

Travel-Friendly Bar. A solid 60g bar skips the bottle entirely, so it packs easily, never spills, and clears liquid restrictions when you travel.

How to Use Onion & Biotin Shampoo Soap – 60g

Step 1. Wet hair and scalp thoroughly with warm water.

Step 2. Rub the bar directly between your palms or along the scalp to build a lather, then set the bar aside on a draining dish.

Step 3. Massage the lather into the scalp and through the length of your hair for 30-60 seconds, letting the biotin, onion extract, and rosemary work through each strand.

Step 4. Rinse thoroughly with warm water and follow with a conditioner if your hair type needs one.

Shelf Life & Storage

Storage. Keep the bar on a well-draining soap dish away from standing water, and store it in a cool, dry place out of direct heat and sunlight between washes.

Shelf life. As a general guide, unopened handmade bars keep well for 12-24 months; once in use, the printed date on the packaging, where present, always takes precedence over this guidance.

Safety Instructions

Patch test. Before first use, test a small amount of lather on your inner wrist or behind the ear and wait 24 hours to check for any reaction.

External use. This bar is intended for the scalp and hair only. Avoid direct, prolonged contact with the eyes, and rinse immediately with water if contact occurs.

Discontinue if needed. Stop use and consult a healthcare professional if you notice redness, itching, or irritation that does not resolve.
