Answer

During Paryushan, it is generally better to avoid shampooing if it is only for comfort, beauty, or routine grooming.

However, if shampooing is needed for health, hygiene, medical reasons, itching, infection, or unavoidable cleanliness, then it may be done with care and restraint.

Explanation

Paryushan is a time for:

• Tapasya — self-discipline
• Sanyam — restraint
• Ahimsa — minimizing harm
• Inner purification rather than outer decoration

So activities related to personal luxury, beautification, or indulgence are usually reduced. Shampooing is not the main issue by itself; the intention matters.

If you are shampooing because:

• hair is dirty due to necessity,
• there is sweat or discomfort,
• there is a scalp problem,
• it is needed for basic hygiene,

then it can be acceptable.

But if it is mainly for styling, fragrance, or looking attractive, it is better to avoid during Paryushan.

Spiritual Understanding

Paryushan teaches us to reduce attachment to the body and focus more on the soul. The ideal spirit is:

• less body-care for pleasure,
• more soul-care through pratikraman, samayik, swadhyay, forgiveness, and restraint.

Takeaway

If shampoo is necessary for cleanliness or health, do it simply and mindfully. If it is for comfort, beauty, or habit, it is better to avoid it during Paryushan.
