Amavasya, or the New Moon day, holds deep spiritual significance in Hindu culture. It’s considered a powerful day for meditation, ancestral rituals, and spiritual practices. However, certain traditional restrictions are often observed—one of them being the belief that one should not wash their hair on Amavasya.

But is this a strict rule, or just a cultural custom? In this blog, we’ll explore both the intent behind this belief and the practical side, so you can decide for yourself.
Understanding the Belief: Why Is Hair Washing Avoided on Amavasya?
1. Spiritual Significance
Amavasya is often dedicated to Pitru Tarpan—rituals for departed ancestors. According to Hindu tradition, during this time, the spiritual connection between the physical and ancestral realms is at its peak. Therefore, people avoid:
- Attending weddings or parties
- Wearing new clothes
- Washing hair or grooming
It is believed that washing hair might wash away spiritual blessings or interfere with ancestral rituals. The act of staying physically simple (no grooming) is a symbolic way of showing humility and respect.
2. Cultural Practices
In many Indian households:
- Hair washing is seen as an act of vanity and self-care.
- On days of spiritual significance, such acts are postponed to maintain a solemn atmosphere.
- It’s also common to avoid bathing during eclipses, Shradh days, or Amavasya tithi.

Can We Wash Hair on Amavasya?
If you’re here searching for a straight answer: Yes, you can wash your hair on Amavasya—unless you are performing a ritual that requires you not to.
Let’s address this from different angles:
✅ Scientific/Health Perspective
- There is no scientific proof that washing your hair on Amavasya causes harm or bad luck.
- Scalp hygiene is essential, especially in Indian weather conditions. Avoiding hair wash for superstitious reasons could even lead to discomfort or infection.
- Doctors and dermatologists recommend regular hair washing as per your hair type—not based on lunar calendars.
🧘♀️ Spiritual Flexibility
- If you’re observing rituals like Tarpan or fasting, you may avoid hair washing until the ritual is over.
- Otherwise, modern spiritual advisors and priests often say: ritual purity depends on intent, not whether you shampooed your hair.
🌏 Regional & Family-Based Variations
Beliefs differ greatly:
- In Tamil Nadu, Andhra, and parts of Maharashtra, some families consider it inauspicious to wash hair or sweep floors on Amavasya.
- In metro cities or working households, these beliefs are loosely followed, if at all.
- Some astrologers suggest avoiding hair wash only during Rahu Kaal or during specific Amavasya events like Somvati Amavasya (falling on a Monday).
📌 Pro tip: Ask your elders or family priest if you follow such customs, but don’t feel guilty if you choose personal hygiene.
🧴 Modern Lifestyle vs. Traditional Beliefs
Balancing spiritual belief and practical hygiene is easy when you follow this approach:
Situation | Should You Wash Hair? | Why? |
---|---|---|
You’re doing Pitru rituals | ❌ No | Focus is on spiritual purity |
You’re not performing rituals | ✅ Yes | No harm in washing |
You have dandruff or itching | ✅ Yes | Health > superstition |
Family traditions restrict it | 🟡 Optional | Respect beliefs or wash before/after |
If you’re going to the office, gym, or a social gathering—feel free to wash your hair. Traditions were never meant to cause discomfort.
Conclusion: Is It Okay to Wash Hair on Amavasya?
The bottom line: Yes, you can wash your hair on Amavasya if you’re not performing rituals that restrict it. The belief stems from cultural respect and spiritual observance, not from any scientific or astrological rule.
If your family upholds these traditions, it’s thoughtful to honor them—especially during collective rituals. But if you’re living independently or prioritize daily hygiene, it’s perfectly fine to wash your hair on Amavasya.
Ultimately, the choice lies with you. Let respect for tradition and practicality coexist in a way that works best for your lifestyle.

FAQs
Can we wash our hair on the day of Amavasya?
Yes, you can wash your hair on Amavasya unless you’re performing specific religious rituals such as Pitru Tarpan or observing a fast. Traditionally, it’s believed that hair washing on Amavasya may wash away spiritual blessings or disturb ancestral energies, which is why some families avoid it. However, from a scientific or hygiene perspective, there is no harm in washing hair on this day if no ritual restrictions apply.
What should we not do on Amavasya Day?
On Amavasya, many traditions advise against grooming activities such as washing hair, cutting nails, or shaving—especially if you’re participating in ancestral rituals. It is also considered inauspicious to start new ventures, travel during Rahu Kaal, or engage in arguments. Instead, it is seen as a spiritually charged day ideal for meditation, offering prayers to ancestors, doing charity, and engaging in self-reflection.
Which days should we avoid washing hair, and which days are considered lucky for it?
Hair washing is often avoided on days like Amavasya, Shradh (ancestral ritual days), and eclipse days. In certain communities, Tuesday and Saturday are also considered inauspicious for washing hair due to astrological beliefs. On the other hand, Friday is considered a lucky day for hair care, especially for women, as it’s associated with beauty, prosperity, and femininity. Thursday is also considered pure and favorable, especially in households that follow Guru traditions. Purnima (Full Moon Day) is seen as a cleansing and spiritually uplifting time, making it ideal for washing hair.
On which day should we not wash hair in astrology?
According to astrology, Tuesday (associated with Mars) and Saturday (ruled by Saturn) are often considered unsuitable for hair washing. These days are believed to carry energies where grooming is discouraged, especially for those who follow traditional astrological practices. Amavasya is also seen as a spiritually sensitive day, particularly connected to ancestral energies, so hair washing is often avoided. Additionally, Rahu Kaal, a time period considered inauspicious each day, is generally avoided for personal grooming tasks like haircuts or hair washing. However, these guidelines are based on belief systems, and there’s no harm in washing your hair if you’re not following these rituals strictly.
