What is NAD+ and Why Does It Matter?

NAD+ is an essential coenzyme present in every living cell. It plays a central role in critical biological processes like energy metabolism, DNA repair, and cell signaling. As we age, the natural production of NAD+ declines, which can contribute to the degradation of cellular functions and may even factor into the aging process of our skin and hair. Its role in safeguarding DNA and supporting the mitochondria (the cell’s powerhouses) makes it an attractive candidate for anti-aging treatments.

Interestingly, while many studies highlight NAD+ for its rejuvenative benefits, some public discussions specifically ask, “Does NAD cause hair loss?” The answer is not straightforward. Instead of directly causing hair loss, low NAD+ levels in aged cells can lead to impaired cellular repair and increased oxidative stress—factors that could eventually impact hair follicles. Conversely, restoring NAD+ may enhance cell regeneration in hair follicles and contribute to hair growth.

NAD+ and Hair Health: Understanding the Connection

Hair follicles are among the many cellular structures that benefit from efficient energy metabolism and robust DNA repair mechanisms. In a healthy state, these processes support the proper cycling of hair growth. Studies have shown that NAD+ plays a crucial role in the regulation of hair follicle biology, including:

• DNA Repair and Cellular Regeneration: NAD+ assists in the repair of damaged DNA in skin cells, including those in the hair follicles. Improved DNA repair means that the cells involved in hair growth can function at their best.
• Mitigating Oxidative Stress: Oxidative damage, which increases with age, negatively affects the hair growth cycle. By boosting NAD+ levels, cells may increase their antioxidant defenses, helping to preserve the delicate structures in hair follicles.
• Energy Production for Cellular Processes: Hair follicles are dynamic mini-organs. They require sustained energy to support the anagen (growth) phase of the hair cycle. NAD+ is central to the mitochondria’s ability to produce energy, thus promoting an optimal environment for hair growth.

While these mechanisms underline the beneficial aspects of NAD+ for hair health, discussions continue as to whether its supplementation can inadvertently contribute to hair loss under certain conditions.

The Science Behind NAD+ and Hair Growth

Recent laboratory studies have provided valuable insights into how NAD+ interacts with hair follicle cells. Researchers have noted that supplementing with NAD+ precursors, such as nicotinamide mononucleotide (NMN), can lead to:

• Enhanced Vascular Endothelial Growth Factor (VEGF) Expression: VEGF is instrumental in promoting blood flow to hair follicles, ensuring that they receive the nutrients and oxygen required for healthy growth. Increased VEGF expression has been observed in studies where NAD+ levels were boosted.
• Upregulation of β-Catenin: This signaling molecule is a key regulator of hair follicle development and regeneration. Higher levels of β-catenin support the transition of hair follicles from the resting (telogen) phase into the active growth (anagen) phase.
• Reduction in Androgen Receptor and DKK-1 Expression: Androgenetic alopecia (pattern hair loss) is linked to the action of dihydrotestosterone (DHT) on androgen receptors. Some research has indicated that treatments enhancing NAD+ can lower the expression of androgen receptors and DKK-1 (a protein inhibitor of the Wnt/β-catenin pathway), factors that contribute to hair thinning.

These studies suggest that rather than causing hair loss, NAD+ supplementation through NMN or similar compounds may actually help counteract hair thinning—especially in scenarios where diminished NAD+ levels contribute to a loss of cellular regenerative capacity. Still, more clinical trials in humans are needed to fully confirm how these laboratory findings translate into everyday outcomes.

NAD+ Versus DHT: Clarifying the Controversy

One of the common questions emerging in the discussion is, “Does NAD cause hair loss?” It is important to note that the underlying issue in many cases of hair loss, especially in androgenetic alopecia, is the effect of DHT (dihydrotestosterone) on hair follicles. DHT is known to contribute to the miniaturization of hair follicles in genetically predisposed individuals. In this context, NAD+'s role may not be as a instigator of hair loss but rather as a counteractive agent that supports the follicle's resilience.

For instance, experiments with NMN treatment in animal models have demonstrated that NMN can reverse hair follicle atrophy and improve hair follicle size, even in DHT-damaged cells. Such findings highlight that:

• NAD+ might protect hair follicle cells from the inflammatory effects induced by DHT.
• Increased NAD+ levels can enhance the expression of growth factors, such as VEGF, promoting hair regeneration.
• By suppressing proteins that are induced by DHT (such as DKK-1), NAD+ may preserve the Wnt/β-catenin signaling pathway, critical for cellular proliferation in hair follicles.

Thus, instead of being a causative factor for hair loss, low NAD+ levels in aging hair follicles might exacerbate the harmful effects of DHT—implying that restoring NAD+ could be a promising treatment for some forms of hair loss.

Lifestyle, Supplements, and Boosting NAD+ Levels

Maintaining optimal NAD+ levels is not only about supplementation—it involves a holistic approach that incorporates diet, exercise, stress management, and lifestyle choices. Research suggests that engaging in regular physical exercise and consuming a balanced diet rich in NAD+-boosting nutrients (such as niacin found in fish, lean meats, and leafy greens) can naturally elevate NAD+ levels.

Supplements like NMN or nicotinamide riboside (NR) are particularly popular among those seeking to boost mitochondrial function and overall cellular energy. These supplements have been shown to:

• Improve energy metabolism
• Enhance DNA repair mechanisms
• Reduce oxidative damage not just in hair follicles but throughout the entire body

As a result, many integrative wellness clinics now offer NAD+ infusion therapies. These therapies aim to elevate NAD+ levels rapidly and can be especially beneficial for individuals experiencing signs of premature aging, including hair thinning and other skin issues. In a clinical setting, NAD+ therapy is often administered intravenously for maximum bioavailability, offering a direct route to replenishing depleted NAD+ stores.

Clinical Research on NAD+ and Hair Regrowth

Emerging clinical evidence suggests that boosting NAD+ levels may have a positive impact on hair follicle health. Several studies (mainly in animal models) have explored how NMN administration can counteract the adverse effects of DHT and oxidative stress on hair follicles. Key findings include:

• Increased Hair Follicle Diameter and Density: NMN has been observed to restore the size of hair follicles that had undergone atrophy due to DHT exposure. This restoration is accompanied by an increase in the number of active hair follicles.
• Enhanced Cellular Proliferation in Dermal Papilla Cells: Laboratory studies using cultured dermal papilla cells (the cells at the base of the hair follicle) have demonstrated that NMN can stimulate cell proliferation, ensuring that the cellular machinery required for hair regeneration remains robust.
• Reduction in Inflammatory Markers: Inflammatory cytokines such as IL-6 and IL-1β are known to adversely affect hair growth. Through its antioxidant properties, NAD+ supplementation has been shown to lower these inflammatory markers, thereby creating a more favorable environment for hair regrowth.

Clinical trials in human subjects are still in the early stages, but initial findings are promising. By regulating the delicate balance between cellular repair mechanisms and inflammatory responses within the scalp, NAD+ therapy may offer a new frontier in the treatment of hair loss.

Potential Concerns: Addressing the “Does NAD Cause Hair Loss” Question

Frequently, cultural anecdotes and individual experiences fuel the question, “Does NAD cause hair loss?” It is vital to differentiate between correlation and causation. The decline in NAD+ levels is a natural part of aging; however, it is the low NAD+ levels—not the supplementation—that correlate with hair thinning and loss. In fact, clinical evidence and research consistently point to the protective and regenerative advantages provided by maintaining or restoring NAD+ levels.

Some users of NAD+ therapy may experience temporary adjustments in their hair shedding cycles as the follicles transition from the resting phase to the active growth phase. This phenomenon, sometimes referred to as “shedding,” is a normal part of the hair regeneration process. Rather than a sign of damage or loss, initial shedding indicates that older hairs are being replaced by new, healthier growth cycles. Therefore, it is incorrect to conclude that NAD causes hair loss; on the contrary, it shows promise for preventing and reversing hair loss due to its beneficial effects on cellular repair and energy metabolism.

How to Incorporate NAD+ Therapy into Your Routine

For those considering NAD+ therapy, it is important to take a comprehensive approach. Here are some tips to help you incorporate NAD+ boosting strategies into your daily routine:

• Diet and Nutrition: Consume foods high in niacin (vitamin B3), such as tuna, chicken, mushrooms, and green vegetables. These help naturally support NAD+ production.
• Regular Exercise: Engage in physical activities that boost mitochondrial function. Exercise is proven to naturally elevate NAD+ levels and improve overall cellular health.
• Stress Management: Chronic stress can deplete NAD+ levels. Practices such as meditation, yoga, and adequate sleep can help maintain optimal levels.
• Supplementation: Consider reputable supplements like NMN or NR. Ensure that they are third-party tested for purity and potency.
• Clinical Treatments: If you’re interested in a more rapid method of NAD+ replenishment, explore NAD+ infusion therapies offered by specialized wellness centers. These advanced therapies deliver NAD+ directly into your bloodstream to maximize its healing and regenerative effects.

By addressing lifestyle factors alongside targeted supplementation or clinical intervention, you can more effectively support hair regrowth and overall skin and cellular health.
