Description
Lion Octo serapie Medicated Shampoo & Conditioner Set, 230 ml × 2
Overview
A two-bottle dandruff set from Lion, one of the four large Japanese household-goods makers. Both bottles carry the same active ingredient — piroctone olamine, which Lion sells under the name Octopirox — and both are registered as 医薬部外品, Japan's quasi-drug class.
The serapie line is the drier-scalp version of Lion's Octo range: same active, formulated so the scalp is not stripped in the process. Lion states a low-irritant formula with no added parabens and a light natural aroma.

Who Is This For?
- Recurring flaking and scalp itch that a cosmetic shampoo has not settled
- Scalps that feel tight or dry after using a standard anti-dandruff shampoo
- People who prefer a lightly scented product over a strongly perfumed one
- Anyone wanting the shampoo and conditioner matched rather than mixed across brands
- Not for you if you react to soy, or if you have broken or inflamed skin on the scalp
How to Use
- Wet the hair and scalp thoroughly.
- Work the shampoo into the scalp — not just the hair — with the pads of the fingers, not the nails.
- Leave it in contact with the scalp for a minute or so before rinsing, so the active has time to act.
- Rinse completely.
- Apply the conditioner to the scalp and hair, then rinse.
Frequency: Daily or every other day while flaking is active; Lion notes that dandruff control depends on regular use rather than one wash.
Full Ingredients
Regulatory class: 医薬部外品 (Japanese quasi-drug). The maker declares an active ingredient and a separate list of other ingredients, which is why the format below differs from a plain cosmetic INCI list.

Shampoo — other ingredients: Sodium Laureth Sulfate, Lauramidopropyl Betaine solution, Sorbitol solution, Polyglyceryl Laurate, BG, PG, POE Hydrogenated Castor Oil, Fragrance, Guar Hydroxypropyltrimonium Chloride, Citric Acid, Ethanol, Anhydrous Ethanol, Nattō (fermented soybean) Extract.
Conditioner — active ingredient: Piroctone Olamine.

Cautions
- Do not use on skin that has eczema, dermatitis, weeping or broken areas — it can make them worse.
- Stop using it if the scalp becomes irritated or itchy after application, and consult a doctor.
- If it gets in the eyes, rinse immediately with water or lukewarm water. See an eye doctor if a foreign-body sensation remains.
- Contains fermented soybean extract. Avoid if you are allergic to soy.
- Store where small children and people with dementia cannot swallow it by accident.
- Dandruff that does not improve after a few weeks of regular use, or that comes with redness, pain or hair loss, should be looked at by a dermatologist rather than treated with a stronger shampoo.

FAQ
What is the medicated ingredient, and what does it actually do?
Piroctone olamine, which Lion markets under the name Octopirox. It is an antifungal. Dandruff of this type is driven by Malassezia, a yeast that lives on most scalps; piroctone olamine limits its growth, which is what reduces the flaking and itching. It is not a moisturiser and not a steroid.
Is this a medicine? Can I take it through customs?
It is a 医薬部外品 — a Japanese quasi-drug, the category between cosmetics and medicines. It is sold openly in Japanese supermarkets without a prescription. Import rules still vary by country, so check your own if you are unsure.
There is soy in this. Does that matter?
It might. Both bottles contain 納豆エキス, fermented-soybean (nattō) extract. Soy is a declarable allergen in the EU, the UK and Japan. If you react to soy, this is the line in the list to look at.
Does it smell strongly?
No. Lion describes a light natural aroma built from fragrance materials it states are entirely naturally derived. It is not fragrance-free, but it is not a strong medicated smell either.
Can I use just the shampoo and keep my own conditioner?
Yes. Both bottles carry the same active, so using the shampoo alone still delivers it. Lion recommends the pair because the conditioner keeps the active on the scalp after rinsing.
