Why Reetha Powder Is the Best Natural Cleanser for Hair (Soapnut Science Explained)
Reetha powder, also known as soapnut powder, has been used for centuries as a natural hair cleanser. Unlike modern shampoos, Reetha cleans the scalp without sulphates, synthetic foaming agents, or harsh chemicals. This article explains the science behind Reetha, how it works on hair, and why it remains one of the most effective natural cleansing solutions today.
1) What is Reetha (soapnut)?
Reetha comes from the dried fruit of the Sapindus tree, commonly called soapnut. In Ayurveda, Reetha is classified as a natural cleanser that removes dirt and excess oil while maintaining scalp balance.
When dried and powdered, Reetha becomes an effective herbal alternative to shampoo, traditionally used for hair washing, fabric cleaning, and gentle skin cleansing.
2) Soapnut science: how Reetha cleans hair
The cleansing power of Reetha comes from natural compounds called saponins. Saponins are plant-based surfactants that create mild foam when mixed with water.
- They lift dirt and oil from the scalp
- They rinse away without stripping natural moisture
- They are biodegradable and scalp-friendly
3) Reetha powder vs chemical shampoo
Most commercial shampoos rely on sulphates for strong foaming. While this feels “clean,” it often strips natural oils and weakens hair over time.
