NMN for Hair Growth: What the Science Says

NMN is best known for energy and longevity. Now there is human research suggesting it supports thicker, healthier hair too. Here is what the science shows, and why NMN PerformMax goes further than NMN alone.

Does NMN help hair growth?

NMN raises NAD+, the coenzyme cells use for energy and repair. NAD+ falls as we age, and hair follicles are some of the most energy-hungry cells in the body. Topping up NAD+ helps give follicles the fuel to stay in their active growth phase, which is where thickness and length come from.

What the first human study found

In 2025, Japanese researchers ran the first human trial of oral NMN for hair (Cosmetics, 2025): 15 women aged 40 to 50 took 500 mg of NMN daily for 12 weeks. Results:

• Thicker strands (average diameter rose from about 75 to 79 micrometres)
• More hairs in the active growth phase (roughly 56 to 88 per cm²)
• More mature, full-thickness hairs
• Less shedding, plus more volume, shine and strength by self-report

It was small and had no placebo group, so it is early evidence, but it is a promising first look that matches the biology.

How NMN supports hair

• Follicle energy: more NAD+ fuels the cells that build each strand
• Longer growth phase: well-resourced follicles stay in the growth (anagen) phase
• Antioxidant support: NAD+ pathways help follicles handle oxidative stress
• Calmer follicles: animal research shows NMN eases inflammation linked to thinning (Molecules, 2024)

NMN supports the hair you have. It is not a cure for hereditary hair loss.

Not just NMN: the NMN PerformMax stack

Most NMN products give you NMN and nothing else. NMN PerformMax is a 4-in-1, and three of its ingredients have their own hair research:

• Panax ginseng: ginsenosides promote hair growth through a mechanism similar to minoxidil and stimulate the dermal papilla cells that drive each follicle (J Dermatol Sci, 2015)
• CoQ10: switches on the genes for hair keratins, the proteins ageing hair loses (Int J Cosmetic Science, 2009)
• Ashwagandha: lowers cortisol, a well-known trigger for stress-related shedding

More than hair

NMN PerformMax is built first as a daily energy and longevity formula. The same NAD+ boost (clinically shown to raise NAD+ by 38% in 60 days) supports:

• All-day energy, with less afternoon slump
• Better endurance and faster recovery
• Sharper focus
• Better sleep and healthier skin
• Metabolism and healthy ageing at the cellular level

Frequently asked questions

Does NMN help hair growth?

Early human research suggests it can support hair thickness and growth-phase activity. A 2025 study found thicker, more active hair after 12 weeks of daily NMN, though larger trials are still needed.

Can NMN regrow hair?

No supplement guarantees regrowth. NMN is best understood as supporting the hair you have, not reversing hereditary hair loss or alopecia.

How long does NMN take to work for hair?

Hair grows slowly. The human study ran 12 weeks, so give it at least 8 to 12 weeks of consistent daily use.

Is NMN safe?

Human trials report NMN is well tolerated at typical doses. If you are pregnant, nursing or on medication, check with your doctor first.

The bottom line

NMN has long been a go-to for energy and healthy ageing, and the science now points to benefits for hair too: thicker strands, more active growth and less shedding. NMN PerformMax pairs premium Uthever® NMN with ginseng, CoQ10 and ashwagandha to support your hair, energy and long-term vitality in one daily capsule.
