The Top 10 Multi-Ingredient Hair Supplements (Countdown Edition)
An older and consistent entrant, HairExcel brings together a wide spectrum of vitamins, minerals, amino acids, and botanicals to support hair structure and growth. Often praised as a cost-effective alternative to premium names, it has steadily gained loyal users thanks to consistent, visible results within a few months.
From one of the UK’s biggest supplement brands, Perfectil Hair delivers a broad formula of over 28 nutrients, including biotin, selenium, zinc, and collagen. It’s a mainstream staple, widely available in high-street pharmacies, and has won over consumers with accessibility and trusted quality.
Philip Kingsley is one of the world’s most respected trichology clinics, and its supplements are built on decades of expertise. The Density and Tricho Complex blends are designed to complement clinical treatments, supporting hair strength and density from within, and carry the authority of a specialist-led brand.
This French pharmacy classic has stood the test of time, remaining popular for over 30 years. Its formula combines essential fatty acids, antioxidants, and key vitamins, making it as much a beauty supplement as a hair-growth aid. With its heritage and strong consumer trust, Phytophanere remains a top choice across Europe.

A pharmacy-grade supplement from Germany, Pantogar has been prescribed internationally for diffuse hair loss and alopecia for decades. Its unique mix of cystine, keratin, and B-vitamins is designed to strengthen hair structure and encourage new growth, giving it credibility that many newer brands lack.
Another pharmacy giant, Priorin is widely trusted in Europe and the Middle East. Its blend of millet extract, biotin, and pantothenic acid has clinical backing for reducing shedding and improving growth in women with diffuse thinning. With decades on the market, it’s one of the most established names in the category.
Born out of Oxford research, but manufactured in Germany, TRX2 takes a unique molecular approach with potassium channel activators such as L-carnitine and nicotinic acid. Targeting follicular activity at a cellular level, it appeals to those seeking a science-driven, specialist solution. Its loyal following has kept it firmly in the top tier of global supplements. Since the early 2010s, TRX2 has been a regular in the "Big Four" of hair supplements.
Originated in Finland, a true classic, Viviscal is backed by multiple clinical studies on its proprietary AminoMar™ marine protein complex. With consistent evidence of improved hair count, thickness, and strength, Viviscal has earned its place as a trusted pharmacy staple across Scandinavia, the UK, US, and beyond. Few supplements can match its track record.
Nutrafol has redefined the modern hair supplement category. With multiple published studies and formulas tailored for women, men, and even postpartum users, it’s the dermatologist’s go-to recommendation in the US. Its clinically proven results, professional endorsements, and huge consumer adoption secure its place as one of the world’s most respected options.
Topping our list is HR23+, the all-rounder supplement that has built a reputation as the most complete formula on the market. Combining 23 carefully chosen ingredients — including biotin, saw palmetto, zinc, collagen peptides, pepita, and nettle extract — HR23+ is designed to reduce shedding and support density in both men and women. With exceptional consumer feedback, high repeat-purchase rates, and growing recognition internationally, it stands as the most powerful multi-ingredient hair supplement available today.
• Evidence quality varies: HR23+, Nutrafol, Viviscal, and TRX2 have peer-reviewed human data on the full formulations; many others rely on ingredient-level science or consumer studies. Manage expectations and stick with any pick for ~3–6 months to judge effect.
• Core nutrients that repeatedly show up across “winners” (and in hair research) include biotin, zinc, vitamins A/C/D/E, collagen/aminos, and sometimes DHT-pathway botanicals like saw palmetto. Diet, stress, hormones, and scalp care still matter a lot.
