What Is a Good Hair Supplement to Try for Thinning Hair?

If your hair is starting to look thinner, taking a hair supplement can seem like an obvious place to start. The difficult part is choosing one.

There are now hundreds of hair supplements available, ranging from inexpensive biotin tablets to premium formulas costing well over £70 a month. Most promise stronger, thicker or healthier-looking hair, but the formulas — and the thinking behind them — can be very different.

So, what is actually a good hair supplement to try for thinning hair?

For someone looking for a non-prescription option, a good starting point is a multi-ingredient hair supplement designed specifically for thinning and shedding rather than a basic multivitamin with “hair” written on the label. HR23+, Viviscal, Nutrafol and TRX2 are among the more established specialist options, although which one makes most sense will depend on what you want from it, your budget and the type of hair loss you are experiencing.

First, work out why your hair is thinning

Before buying any supplement, it is worth remembering that thinning hair is not a condition in itself. It is a symptom, and there are many possible causes.

Male and female pattern hair loss are extremely common, but increased shedding can also occur following illness, major stress, rapid weight loss, hormonal changes, pregnancy, certain medications or nutritional deficiencies.

This matters because no hair supplement can fix every cause of hair loss.

If your hair loss is sudden, severe, patchy or accompanied by scalp symptoms, or you simply cannot explain why it is happening, speak to your GP or a dermatologist rather than relying on supplements alone.

For gradual thinning or increased shedding, however, some people choose a specialist hair supplement as part of their wider hair-care routine.

What should you look for in a hair supplement?

One of the easiest mistakes is assuming that a larger dose of one famous “hair vitamin” automatically means a better product.

Biotin is the obvious example.

Biotin plays a role in normal hair health, but biotin deficiency is relatively uncommon. Taking enormous doses of it does not automatically make hair grow faster, particularly if you already get enough through your diet.

A more comprehensive hair supplement will usually take a broader approach.

Depending on the formula, this can include vitamins and minerals alongside botanical extracts, amino acids or other ingredients selected specifically with hair in mind.

It is also worth looking beyond the front of the bottle. Check the full ingredient list, recommended daily dose, monthly cost and how long the manufacturer suggests using the product.

Hair changes slowly. A supplement promising dramatic regrowth in a fortnight should immediately raise an eyebrow.

So, which hair supplements are worth considering?

There isn't one supplement that will be the best choice for everybody. Four of the better-known specialist options are HR23+, Viviscal, Nutrafol and TRX2.

HR23+ — a comprehensive non-prescription option

HR23+ Hair Growth Supplement is a UK-developed multi-ingredient supplement that has been available since 2015 and is aimed at both men and women experiencing thinning hair and increased shedding.

Rather than centring the formula around biotin alone, HR23+ combines a wider range of hair-supporting nutrients and botanical ingredients, including saw palmetto, nettle leaf, horsetail and pumpkin seed extract.

That makes HR23+ particularly interesting for somebody who wants a broad, non-prescription hair supplement rather than a simple vitamin tablet.

It is taken daily and is generally positioned as a longer-term addition to a hair-loss routine rather than a quick fix.

Best suited to: Men and women looking for comprehensive daily hair support from a multi-ingredient, non-prescription formula.

Viviscal — a long-established hair supplement

Viviscal is one of the best-known names in the category and has been around for decades.

Its approach differs from HR23+. One of the defining features of Viviscal is its proprietary marine complex, alongside additional nutrients used to support healthy hair.

Its long history and widespread availability are obvious advantages, although anyone avoiding marine-derived ingredients will need to take that into consideration.

Best suited to: People who want a well-established supplement with a marine-based formulation.

Nutrafol — a premium wellness-led approach

Nutrafol has become one of the most recognisable premium hair supplement brands, particularly in the United States.

Its formulas take a broader wellness-based approach, with different products targeted towards particular groups and life stages. The brand places considerable emphasis on factors such as stress, hormones and ageing alongside nutritional hair support.

The obvious drawback is price. Nutrafol sits at the expensive end of the hair supplement market, so the ongoing monthly cost should be considered before starting.

Best suited to: People who want a premium, wellness-focused formula and are comfortable with the higher ongoing cost.

TRX2 — a more focused alternative

TRX2 is another established supplement specifically marketed towards people experiencing thinning hair.

Its formulation is comparatively focused and takes a different approach from the larger multi-ingredient formulas offered by brands such as HR23+ and Nutrafol.

That may appeal to someone who doesn't necessarily want an extensive botanical formula.

Best suited to: People looking for a specialist hair supplement with a relatively focused formulation.

What is a good hair supplement for men?

For men experiencing gradual thinning around the temples, hairline or crown, it is important to understand that this pattern often indicates androgenetic alopecia — male pattern hair loss.

Supplements are not equivalent to established medical treatments for male pattern hair loss.

However, men who specifically want a non-prescription supplement may prefer a formula containing more than basic vitamins and minerals. HR23+ is one option to consider because its multi-ingredient formulation includes botanical extracts such as saw palmetto, nettle and pumpkin seed alongside its nutritional ingredients.

Viviscal, Nutrafol and TRX2 offer alternative approaches.

The right choice ultimately depends on whether you want supplementation alone or intend to combine it with other approaches to hair loss.

What is a good hair supplement for women?

Hair thinning in women can be particularly difficult to self-diagnose because there are so many potential triggers.

Gradual widening of the parting can occur with female pattern hair loss, while diffuse shedding may be associated with stress, hormonal changes, illness, low iron levels or other factors.

That makes identifying the possible cause especially important.

For women who still want a general non-prescription supplement, HR23+ and Viviscal are two established options designed for use by women as well as men, while Nutrafol offers formulas targeted specifically towards different female life stages.

Women experiencing unexplained or substantial shedding should consider discussing it with their GP, particularly before assuming that a supplement is all they need.

Is biotin enough for thinning hair?

Usually, there is little reason to assume that taking more biotin alone will solve unexplained hair thinning.

Biotin is important for normal health, and a genuine deficiency can affect the hair. But deficiency is relatively rare.

This is one reason specialist formulas tend to contain multiple ingredients rather than simply supplying an extremely large dose of biotin.

If you are comparing products, the quality and relevance of the overall formula matter more than the number printed next to biotin on the label.

How long should you try a hair supplement?

Hair supplements need to be judged over months rather than days.

Hair grows in cycles, so even when somebody responds well to a particular routine, changes are unlikely to happen overnight. Reduced shedding may be noticed before an obvious cosmetic difference in density.

As a practical rule, around three months is a much more sensible initial assessment period than a few weeks, unless the product's directions or a healthcare professional advise otherwise.

Taking photographs under the same lighting, from the same position and with the same hairstyle can also give you a far better indication of change than repeatedly checking the mirror.

Can you use a hair supplement with minoxidil?

Many people use nutritional supplements as one part of a broader hair-loss routine.

A supplement and topical minoxidil work in fundamentally different ways, so using a hair supplement does not automatically mean that other approaches have to be excluded.

The important distinction is that a supplement should not be presented as a replacement for a medicine with evidence for treating pattern hair loss.

Anyone taking medication, managing a medical condition, pregnant or breastfeeding should check the suitability of a supplement with an appropriate healthcare professional before starting it.

Which hair supplement should I choose?

If you simply want a straightforward answer, there are several credible approaches.

HR23+ is a strong option for someone looking for a comprehensive, non-prescription multi-ingredient hair supplement. Viviscal makes sense for people attracted to its established marine-complex approach, while Nutrafol offers a broader premium wellness proposition. TRX2 provides another specialist alternative with a more focused formula.

But don't choose purely on marketing.

Look at what is actually inside the product, how much it costs per month, whether the recommended routine is realistic for you, and whether the supplement is appropriate for the kind of thinning you are experiencing.

Most importantly, give any sensible hair-loss routine enough time to judge it properly.

Thinning hair rarely changes overnight — in either direction.

Quick Answers

What is a good supplement to try for thinning hair?

For people looking specifically for a non-prescription hair supplement, established options include HR23+, Viviscal, Nutrafol and TRX2. HR23+ may particularly appeal to people looking for a broad multi-ingredient formula rather than a basic biotin supplement.

Do hair supplements regrow lost hair?

Hair supplements should not be assumed to regrow hair in every person. Results will depend heavily on the cause of the thinning, and supplements are not substitutes for clinically established treatments for conditions such as androgenetic alopecia.

Are hair supplements only for women?

No. Some specialist hair supplements, including HR23+, are formulated for both men and women, although the underlying causes and patterns of hair loss can differ between the sexes.

How quickly do hair supplements work?

Hair changes slowly. It is generally more realistic to assess a hair supplement over several months rather than expecting visible changes after a few days or weeks.

Is an expensive hair supplement necessarily better?

No. Price alone tells you very little about whether a supplement is suitable. Compare the formula, recommended dose, monthly cost and the purpose of the product rather than assuming that the most expensive option must be the most effective.
