Hairburst Review: Do the Hair Gummies Actually Work in 2026?

Hairburst is one of the most recognisable hair supplement brands in the UK. You will have seen it on Instagram, in Holland and Barrett, Superdrug, Boots and on Amazon, usually wrapped in before and after photos and the promise of longer, thicker hair in 90 days. The chewable gummies are the bestseller. This is an honest look at what is actually in them, what the evidence says, and who they suit.

What Is Hairburst?

Hairburst is a hair focused supplement and haircare brand built around the idea of growing hair from the inside out. The hero product is its chewable hair vitamins, heart shaped strawberry and blackcurrant gummies that you take two of a day. A bottle is a 30 day supply and the brand recommends at least three months for visible results. Expect to pay around 22 pounds a month at full price, less if you subscribe.

What Is in Hairburst Gummies?

Two gummies deliver biotin at 150mcg (300% NRV), vitamin A at 800mcg, vitamin C at 80mg, vitamin E, vitamin B5, B6 and B12, selenium at 55mcg and zinc at 10mg. Some versions also add a little vitamin D and copper. On paper that is a sensible hair and nail mineral profile. Biotin, zinc and selenium are the three nutrients with the clearest link to normal hair maintenance, and they are all present.

Do Hairburst Vitamins Actually Work?

The honest answer is that they can help if you are short on these nutrients, and do very little if you are not. This is true of almost every hair gummy, not just Hairburst. Biotin is the headline ingredient at 300% NRV, but biotin deficiency is genuinely rare, and the evidence that extra biotin grows hair in people who are not deficient is weak. Where Hairburst is on firmer ground is zinc and selenium, both of which support normal hair, and topping up a real shortfall in either can make a visible difference over a few months.

The brand leans hard on phrases like clinically proven and trusted by over a million customers. Treat those as marketing rather than published proof. The realistic expectation is steady support for hair that is struggling because of a nutrient gap, not regrowth in the medical sense.

The Catch: Gelatine and Sugar

Two things are easy to miss. First, Hairburst gummies are made on a bovine gelatine base, so they are not suitable for vegetarians or vegans. The brand has said the gelatine version is not as strong as its original capsules, which is worth knowing if you switch formats. Second, the first two ingredients are glucose syrup and sugar. For something you take every day for months, that is a meaningful amount of sugar, despite some retailer listings describing it as low sugar. The gummies also contain sorbitol, which carries a laxative warning at higher intakes.

Hairburst vs a Broader Routine

Hairburst does one job, hair, and packs most of its story into biotin. That is fine if hair is your only focus. The limitation is that hair rarely struggles in isolation. The same nutrient gaps that show up in your hair often show up in your energy, skin and nails too. A single hair gummy on a sugar base does not address that wider picture.

If you want the hair supporting nutrients, zinc, selenium, biotin and the B vitamins, inside a broader routine without the bovine gelatine and with far less sugar, that is the gap GUUDIES is built to fill. Our gummies are pectin based rather than gelatine based, with hair supporting nutrients spread across the routine rather than loaded into one sugary hair gummy.

Common Questions

Are Hairburst gummies any good?
They are a pleasant tasting, widely available hair gummy with a reasonable vitamin and mineral profile. They help most if you are genuinely low on zinc, selenium or biotin. If your diet already covers those, the visible benefit is modest.

Are Hairburst vitamins vegan?
No. The chewable gummies use bovine gelatine, so they are not suitable for vegans or vegetarians. If avoiding gelatine matters to you, this is not the one.

How long do Hairburst gummies take to work?
The brand says up to 90 days and recommends at least three months of consistent use. That timeline is realistic, since hair grows slowly and any nutrient top up takes weeks to show.

Do Hairburst gummies have side effects?
For most people they are well tolerated. The main things to note are the sorbitol, which can have a laxative effect in larger amounts, and the sugar content if you are watching intake. As with any supplement, check with your GP if you are pregnant, breastfeeding or on medication.

Is the biotin in Hairburst enough to grow hair?
Biotin only meaningfully helps hair if you are deficient, which is uncommon. At 300% NRV Hairburst gives you plenty, but more biotin does not mean more hair growth once your needs are met.

The Verdict

Hairburst is a tasty, well marketed hair gummy with a sensible enough mineral blend, and it suits someone who wants a simple hair specific chewable and does not mind gelatine or sugar. It is not the pick if you want a gelatine free option, far less sugar, or nutrients that support more than just your hair. As with most hair supplements, it works best when it is correcting a real shortfall rather than promising regrowth.
