Does NAD+ Help with Hair Loss? The Science on Regrowth Benefits & NAD Treatments

Key Takeaways

  • Animal studies show that boosting NAD+ levels through nicotinamide mononucleotide can reverse hair follicle atrophy, reduce hair thinning, and promote hair regrowth.
  • NAD+ supports hair health through cellular energy production, DNA repair, and activating sirtuins that protect hair follicle stem cells from oxidative stress and aging damage
  • NAD+ treatments are available through injections, nasal sprays, and supplements, with injections showing the highest bioavailability for cellular repair and anti-aging effects

Seeing thinning hair shakes your confidence, especially if you’ve tried many solutions with disappointing results. So, does NAD+ help with hair loss? 

Scientific evidence shows promising results. Boosting NAD+ levels reverses hair follicle damage and stimulates new growth by enhancing cellular repair mechanisms. 

This guide explains the research on NAD+ hair growth, different delivery methods, and how treatments like NAD+ injections might support your hair regrowth journey.

NAD+ and Its Relevance to Hair Health

Your hair follicles are among the most metabolically active tissues in your body. They cycle through different phases constantly, requiring massive amounts of energy for healthy growth.

Nicotinamide adenine dinucleotide’s role in cellular processes keeps your hair follicles healthy and functioning. As you age, your body's natural NAD+ levels decline significantly, which affects cellular energy production and DNA repair mechanisms.

When NAD+ levels drop, your hair follicles can't maintain proper functioning, leading to hair thinning and eventual hair loss.

Research shows that restoring NAD+ levels through targeted anti-aging treatments helps regenerate damaged hair follicles and reduce oxidative damage that hastens hair loss concerns.

Biological Functions of NAD+ That Impact Hair

To understand how NAD+ may help with hair loss, we first need to look at its key biological roles, many of which directly influence the health and growth cycle of hair follicles.

Cellular Energy Production and Hair Follicle Function

Your hair follicles need massive amounts of cellular energy to grow new hair continuously through the anagen phase of the hair growth cycle. This active growth phase can last two to seven years, depending on your genetics and health.

NAD+ fuels this process by supporting mitochondrial function and ATP production. Without enough NAD+, your hair follicles essentially run out of fuel.

This energy shortage forces hair follicles into early resting phases, shortening your hair growth cycle and leading to thinner, weaker hair over time.

DNA Repair and Protection from Oxidative Stress

Oxidative stress creates free radicals that damage your hair follicle cells and accelerate aging. When your cells can't repair this damage fast enough, your hair follicles become weaker and less productive.

NAD+ enzymes fix DNA breaks and combat oxidative stress from environmental factors, UV exposure, and chronic stress. Understanding how NAD+ supports brain health helps explain how these same protective mechanisms benefit your scalp health and hair follicle development.

NAD+ also activates sirtuins, proteins that regulate cell survival and stress resistance. 

Research Insights on Hair Regrowth Potential

Recent studies are beginning to shed light on how cellular health and specifically NAD+ might influence hair follicle regeneration and overall scalp vitality.

Findings from Animal-Based Studies

Animal studies provide the strongest evidence for NAD+ hair growth benefits. Researchers found that nicotinamide mononucleotide supplementation reversed hair follicle atrophy caused by DHT, a hormone linked to pattern baldness.

Treated animals also showed higher levels of VEGF and β-catenin expression, both key for hair follicle health and regrowth. These markers indicate active hair follicle regeneration and improved cellular health.

Most importantly, the treated mice showed a significant transition from resting hair follicles to active hair follicles in the growth phase.

Early Observations in Human Applications

Limited human research exists here but early observations suggest potential benefits. 

Still, NAD+ is already showing up in NAD-infused hair and nail products, as well as IV therapy clinics offering NAD+ Hair Revive Treatment and NAD+ Hair Ampoule therapies.

Study Type Key Findings Limitations
Animal Studies Reversed hair follicle atrophy, increased hair density Results may not translate to humans
Human Applications More human trials needed Small sample sizes, limited data

NAD+ Forms and Administration Methods

Which form of NAD+ gives the best results? Here’s a breakdown of the most common administration methods and how they compare.

NAD+ Injections

Injections deliver NAD+ directly into the fat cells for steady release into the bloodstream for maximum absorption. This method bypasses digestive breakdown, ensuring your hair follicles receive optimal concentrations for cellular repair and energy production.

Many people choose injections because they provide the highest bioavailability. When you learn how to inject NAD+ properly, you can self-administer treatments at home safely.

Pros

  • Highest bioavailability for hair follicle health
  • Direct delivery to cellular machinery 
  • Fastest results for cellular energy boost

Cons:

  • Requires injection technique 
  • Higher cost ($199-275 monthly) 
  • Potential injection site reactions

NAD+ Nasal Spray

NAD+ nasal spray offers convenient daily dosing with rapid absorption through nasal membranes. Many people find this method more comfortable than needles.

Pros

  • Easy daily administration
  • More affordable option 
  • No injection anxiety

Cons

  • Lower concentration than injections 
  • Requires consistent daily use

When comparing NAD+ injection vs nasal spray delivery, injections typically provide superior results for cellular regeneration and hair follicle support.

Other NAD+ Supplements

Oral NAD+ supplements include nicotinamide riboside and nicotinamide mononucleotide pills. These precursors convert to NAD+ in your body, but absorption rates are lower when taken via pills vs injections or nasal sprays.

Some even take NMN and NAD+ together.

IV therapy provides another option, though it is much more expensive and requires clinical visits which can be inconvenient.

Lifestyle Factors That Support NAD+ and Healthy Hair

Sometimes thinning hair comes from lifestyle and dietary habits. These lifestyle shifts can help your body produce more NAD+ naturally and promote healthier hair from within.

Stress Management and Sleep Quality

Chronic stress depletes your natural NAD+ production while triggering inflammatory cytokines that damage hair follicles. Managing stress through meditation, exercise, or therapy supports both NAD+ levels and hair health.

Quality sleep is equally important because your body produces NAD+ during deep sleep phases. Poor sleep disrupts this natural production, creating a cycle of declining cellular health and hair loss.

Nutrition and Physical Activity

Eating foods rich in NAD+ precursors supports your body's ability to maintain adequate levels. Turkey, fish, mushrooms, and green vegetables provide building blocks for NAD+ synthesis.

Regular physical activities boost mitochondrial health and increase NAD+ production. This creates a positive cycle where exercise improves cellular energy production, which in turn supports healthier hair growth.

Exercise also improves blood circulation to your scalp, delivering more nutrients to your hair follicles. Better circulation supports the active growth phase of your hair cycles. 

Here are the top 5 NAD+ supporting foods:

  1. Turkey and chicken
  2. Tuna and salmon
  3. Mushrooms
  4. Green peas
  5. Avocados

Additional Lifestyle Considerations

Lifestyle factors like smoking, excessive alcohol consumption, and poor diet can accelerate NAD+ decline. Making healthy lifestyle choices supports your body's natural production of this vital coenzyme.
