The 30-second answer
Justine Blue is two products: hair capsules (amino acids, minerals and vitamins) and an anti-dandruff shampoo (selenium sulfide and piroctone olamine). We opened no published study on either by name. A 2026 review of commercial hair supplements (14 studies, 967 participants) found a rise in growing-hair density but no significant difference in total hair count, and on other brands. The shampoo’s ingredients (selenium sulfide and zinc pyrithione) have dandruff trials, but the shampoo page does not state the concentrations.
What are the two products?

#2
80 ml175 ml
Justine Blue Anti-Dandruff Shampoo – 80 or 175 ml
Selenium sulfide and piroctone olamine with four plant oils

- The page: for oily and dry dandruff, in two sizes with the same ingredients
- The page: twice a week, left on for 5 minutes then rinsed
Heads-up: The page does not state the selenium or piroctone percentage, and the price follows the size
The hair capsules: what does research say?
The 2026 Alanazi review (J Cosmet Dermatol, 14 studies, 967 people with hair loss or thinning) on commercial supplements (Nutrafol, Viviscal, Nourkrin and others, not Justine Blue) found versus placebo: lower telogen (shedding) hair density (difference −5.91), higher anagen (growing) density (+10.48) and a lower telogen proportion; but total hair count did not change significantly (p = 0.06), participants’ ratings favoured supplements, and adverse events were few. The authors called the results preliminary and asked for stronger independent research. And the 2019 Almohanna review of vitamins and minerals (vitamins A, B, C, D and E, iron, selenium and zinc) said their role is important but not entirely clear, that deficiency may be a modifiable factor, and that large double-blind trials are needed.
- Justine Blue: the page gives no cysteine, zinc or selenium doses, so we cannot compare it with any study.
- Timing: the review covered studies of 12 weeks to 12 months; the page says at least 3 months.
- The page itself: it does not treat hereditary baldness or thyroid- or anaemia-related hair loss, and it should not be combined with high zinc or selenium.
The shampoo: its ingredients have trials
| Study | Sample and strength | Result |
|---|---|---|
| Danby 1993 | 246 patients with moderate to severe dandruff: ketoconazole 2% versus selenium sulfide 2.5% versus placebo | Both beat placebo significantly, with ketoconazole better on day 8 only; and all nine adverse events were with selenium |
| Piérard 2002 | 331 patients with severe dandruff: ketoconazole 2% versus zinc pyrithione 1%, 4 weeks | A 73% improvement with ketoconazole and 67% with zinc pyrithione, with ketoconazole significantly better and with fewer relapses; both well tolerated |
| Farris 2026 | 87 patients with moderate to severe dandruff, 6 weeks: selenium disulfide 0.6% versus ketoconazole 2% | A 77.9% fall versus 69.5% on the severity scale, with no significant difference between the two; selenium was better for hair softness; tolerability excellent |
- These shampoo ingredients have evidence on dandruff, but the studies were on specific strengths (1%, 2.5% and 0.6%) and the Justine Blue page does not state its strengths, so we cannot say it gives the same result. And we opened no study on piroctone olamine.
- Use per the page: shake the bottle, twice a week, leave on for 5 minutes then rinse.
- Severe or persistent dandruff or with skin inflammation: a dermatologist.
Ask a doctor or pharmacist first if
- Hair loss is sudden, heavy or in patches, or after childbirth, illness or a harsh diet: the cause needs a diagnosis (thyroid, anaemia or other).
- You are pregnant, breastfeeding or take regular medicines, or take high doses of zinc, selenium or biotin.
- You are allergic to any ingredient or essential oils, or have an irritated or injured scalp.
- Dandruff is severe or persists after a month of regular use, or comes with redness and scaling on the face or body.
- You will have lab tests: tell the doctor about all supplements you take (the page itself warns about biotin).
