Quick answer: The best hair growth vitamins UK combine Biotin, Zinc, Vitamin D, Iron support, MSM and plant-based DHT blockers — not Biotin on its own. Take them daily for at least 3–6 months. Glowwa Hair Food is our pick for UK customers because it covers all of these in one daily dose.
The best hair growth supplements UK — our 2026 ranking
We compared the leading hair growth supplements on sale in the UK on formula completeness, ingredient doses, value per day, and the results we see on clients in our Falkland salon. Here is the ranking:
| Rank | Supplement | Key ingredients | Format | Best for |
|---|---|---|---|---|
| 1 — Winner | Glowwa Hair Food | Biotin, Zinc, MSM, Vitamin C, plant-based DHT blockers | 2 capsules daily (~£1.05–£1.17/day) | Overall thinning — women & general use |
| 2 | Glowwa Hair Food MENO™ | As above plus extra Zinc and plant sterols | 2 capsules daily | Menopause-related hair loss |
| 3 | Viviscal Woman | AminoMar™ marine complex, Biotin, Zinc | 2 tablets daily | Established brand loyalists |
| 4 | Hairburst | Biotin, Collagen, Zinc | Capsules / gummies | Younger users, gummy fans |
1. Glowwa Hair Food — best overall (our winner)
The most complete formula we stock: Biotin, Zinc, MSM, Vitamin C and plant-based DHT blockers in one daily dose, with matched versions for menopause (MENO™) and men (MENS™). It is the supplement we recommend in the salon because it is the one clients actually finish — and reorder. Read real customer experiences on our Glowwa reviews page and our customer reviews, or the full honest Glowwa review.
2. Glowwa MENO™ — best for menopause hair loss
Same complete base formula with extra Zinc and plant sterols aimed at hormonal thinning. If menopause is the trigger, this beats any generic multivitamin. See our menopause hair loss guide.
3. Viviscal Woman — the established alternative
A long-standing brand built around its AminoMar™ marine complex. A decent formula, but pricier per course and not suitable for anyone avoiding fish-derived ingredients. We compared them head to head in Glowwa vs Viviscal.
4. Hairburst — best for gummy fans
Popular and pleasant to take, but the gummy format limits the active dose, so it leans heavily on Biotin. Fine for maintenance; less convincing for visible thinning.

What to look for in a hair growth supplement
Hair is one of the first things your body stops prioritising when nutrition, stress or hormones are out of balance. That is why the best vitamins for hair work from the inside, feeding the follicle rather than coating the strand. When comparing hair supplements, look for these ingredients at meaningful doses:
- Biotin (Vitamin B7) — supports keratin production, the protein hair is made of.
- Zinc — essential for follicle repair and a common shortfall in people with shedding.
- Vitamin D — low levels are strongly associated with hair thinning, especially in the UK.
- Iron support & Vitamin C — iron carries oxygen to the follicle; Vitamin C helps absorb it.
- MSM (sulphur) — supports the strength and elasticity of the hair shaft.
- Plant-based DHT blockers — help reduce the hormonal signal behind pattern thinning.
Avoid single-ingredient "mega-dose Biotin" gummies. High Biotin alone rarely helps unless you are genuinely deficient, and it can interfere with some blood tests.
Hair growth tablets, capsules or powders — does the format matter?
Hair growth tablets, capsules and powdered sachets all deliver the same nutrients; the format only matters for whether you will actually take it every day for six months. Tablets are the cheapest per dose and the easiest to travel with. Powders suit anyone who dislikes swallowing tablets. Gummies are the weakest option of the three — the sugar and the physical size of a gummy limit how much active ingredient fits inside, which is why gummy formulas so often lean on biotin alone. Pick whichever you will not abandon in week four.
Vitamins for hair vs hair growth supplements — what's the difference?
A hair vitamin usually means a single nutrient, or a basic multivitamin marketed for hair. A hair growth supplement is a complete formula: vitamins, minerals, amino acids and botanicals chosen to work together across the whole growth cycle. If your hair is shedding, thinning or growing slowly, a complete supplement almost always outperforms a standalone vitamin.
The best hair supplements for women
Women's hair thinning is most often driven by hormones, iron levels, post-partum changes or stress — so the best hair supplements for women address more than one cause at once. Our recommendations by situation, including hair supplements for menopause and general thinning:
| Your situation | Best option | Why |
|---|---|---|
| General thinning, dullness, slow growth | Glowwa Hair Food Original | Complete daily formula — Biotin, MSM, Zinc and DHT blockers |
| Peri-menopause or menopause thinning | Glowwa Hair Food MENO™ | Extra Zinc and plant sterols aimed at hormonal hair loss |
| Post-partum or high-stress shedding | Glowwa Hair Food Original | Replenishes the nutrients depleted during recovery |
| Hair, skin and nails together | Original + Collagen Creamer™ | Adds marine collagen for whole-body support |

The best hair supplements for men
Men usually need a formula weighted towards DHT support rather than iron. Glowwa Hair Food MENS™ is designed for density and reduced shedding in men. If you're noticing a receding hairline or worrying about going bald, read our menopause and male hair loss guide first.
How long do hair growth supplements take to work?
Hair grows roughly 1cm a month, so nothing works overnight. A realistic timeline for a good hair supplement:
- Weeks 6–8 — noticeably less hair in the brush and shower.
- Month 3 — fine new regrowth appearing around the hairline and parting.
- Months 4–6 — visible thickness, better shine and stronger nails.
Consistency matters far more than brand. Missing days resets progress, which is why multi-month bundles tend to produce better results than a single tub. See the cheapest way to buy a full course →
The best hair supplements for thinning hair
If your hair is getting finer rather than falling out in handfuls, you are looking for hair thickening supplements rather than a shedding treatment — and the priority shifts. Thinning strands respond to the building blocks of the strand itself: MSM for sulphur, L‑lysine and rice protein for keratin, zinc for follicle repair, and iron support with vitamin C so oxygen reaches the follicle in the first place. The best hair supplements for thinning hair carry all of those together rather than one at a headline dose. Our ingredients guide explains what each one actually does.
