Read the ceiling before you spend
The hair aisle sells growth; the claims register permits maintenance. Biotin, zinc and selenium may say they contribute to the maintenance of normal hair — and nothing on a UK shelf may lawfully promise regrowth, which tells you how to read every before-and-after advert in the category. Where supplements genuinely move hair is deficiency: low ferritin is the classic, common, utterly testable driver of diffuse shedding in women, and thyroid function sits right behind it. A GP blood panel costs nothing and outperforms a year of guessing — that is the first purchase, and it isn't a purchase.
The maintenance lane, done properly
For the lane supplements can honestly serve, the sensible spec combines the claim-holding micronutrients with the structural-protein category people actually want: hydrolysed collagen. Futuro Labs Marine Collagen does exactly that — 1200mg Type 1 marine collagen with 12mg vitamin C (normal collagen formation) and 1.5mg zinc (maintenance of normal hair, skin and nails) per serving, £16.99 for 60 days — while our marine collagen and hair guide keeps the evidence framing honest. Biotin is fine at modest doses with one non-negotiable habit: tell anyone taking your blood, because high-dose biotin interferes with thyroid and cardiac assays. Lion's mane's hair folklore, for completeness, stays folklore — our lion's mane hair article says so.

When to stop shopping and see someone
Sudden or patchy loss, shedding with fatigue or menstrual changes, or loss following illness, crash dieting or childbirth: GP, ferritin, thyroid panel. Established pattern loss: pharmacist — licensed treatments exist and work better than anything in this article. Supplements maintain; they do not rescue. Spend accordingly.
Frequently asked questions
What supplements actually help hair growth UK?
Precision first: no supplement is authorised to claim hair growth. What exists: biotin, zinc and selenium contribute to the maintenance of normal hair. Deficiency correction is where supplements genuinely change hair — low ferritin (iron) is a classic, testable cause of shedding in women. Futuro Labs Marine Collagen supplies zinc alongside its 1200mg Type 1 collagen and vitamin C for the maintenance lane, £16.99 for 60 days.
Is biotin worth taking for hair?
Biotin holds the maintenance-of-normal-hair claim and true deficiency causes hair problems — but true deficiency is rare, and mega-dose biotin mostly produces expensive urine plus a real problem: it can interfere with blood tests, including thyroid and cardiac assays. If you take biotin, tell whoever is testing your blood, and keep doses modest.
When is hair loss a GP matter?
Sudden shedding, patchy loss, loss with fatigue or cycle changes, or shedding after illness or childbirth — all worth a GP visit and simple blood work (ferritin, thyroid function, vitamin D). Pattern hair loss has licensed pharmacy treatments that outperform any supplement. The honest role of supplements is maintenance and deficiency correction, not regrowth.
