Origins of the belief

The practice known as “lunar haircuts” is rooted in agricultural, astrological, and folk traditions. The Farmers’ Almanac recommends certain haircut dates aligned with the moon’s phases, much like planting crops by the moon to optimize growth. Major haircare brands like Schwarzkopf suggest trimming hair between the new moon and the full moon to promote regrowth. Even celebrities reportedly follow this ritual, convinced that the moon positively influences hair vitality.

And what about science?

Currently, no scientific evidence supports the idea that lunar phases affect hair growth. The real factors influencing hair growth are well known: genetics, hormones (estrogen, testosterone, DHT), nutrition, and lifestyle.

Scientific reviews also highlight the lack of correlation between the moon and human biological functions: the supposed links between the full moon and behavior or childbirth are largely considered illusory and unconfirmed.

Why does this belief persist?

Several mechanisms explain its longevity:

• Placebo effect: believing that a lunar haircut helps hair grow may change how we perceive the results.
• Regular routine: following a lunar calendar encourages people to schedule haircuts regularly—something that indirectly benefits hair health.
• Confirmation bias: people remember the times when it “worked” and dismiss less convincing outcomes.
• Symbolic and wellness aspect: this ritual connects people with natural cycles and can serve as a mindful act of self-care.

Community voices

On community platforms like Reddit, opinions are mixed: some claim they notice a difference, while others realistically point out that hair follicles don’t “feel” the moon. For many, following the lunar calendar remains a personal ritual that feels beneficial—even if no measurable scientific impact exists.

A personal ritual, not a magic method

Choosing to cut your hair with the moon can be a pleasant ritual of self-care, a mindful pause in your routine. But for visible results, it’s better to rely on concrete actions:

• Regular trims to prevent split ends and improve hair quality.
• A nutrient-rich diet with biotin, iron, zinc, and vitamins A, C, and E.
• Gentle care: limiting heat, using suitable products, and protecting hair from external stressors.
• A healthy lifestyle: quality sleep, stress management, and hydration.

Conclusion

Cutting your hair according to the moon is a practice steeped in symbolic and cultural traditions. However, if your goal is stronger, healthier hair, focus on consistent care, a balanced diet, hydration, regular trims, and the right products.
