How Ancient China Washed Hair: Grains, Fermented Waters, and Ritual

Published

A historical account of ancient Chinese hair washing becomes far more interesting when we set aside modern marketing myths of "secret imperial potions" and open the actual classical texts. Early Chinese grooming was defined by structured timing, natural plant and grain chemistry, and a deliberate sequence of care from warm wash to post-wash combing.

By examining classical texts like the Liji (Book of Rites) alongside modern materials research at facilities like SPring-8, we can see how historical households cleansed the scalp—and how that same sequential philosophy translates into a convenient modern routine with the CYN-SILK collection.

Classical Sequence vs. Modern CYN-SILK Ritual: A 4-Step Bridge

You do not need to boil honey-locust pods or save bowls of millet water to practice intentional, material-minded hair care today. Compare how the classical sequence maps onto our current collection:

Grooming Stage Classical Chinese Practice (Liji & Materia Medica) Modern CYN-SILK Counterpart
1. Scheduled Cleansing (Mu 沐) Heating water and washing hair on a deliberate multi-day cadence ("wash hair every three days, bathe every five" in Liji · Neize) using grain rinse water (Pan 潘) or saponin pods (Zao Jia). Cleanse face, body, and hair with 100 g No.03 Nourishing Botanical Soap ($24) (softer, nourishing feel) or No.04 Ink Jade Cleansing Soap ($24) (stronger clarifying feel).
2. Drying & Combing Drying with dedicated cloths (Liji · Yuzao) and unhurried wide-tooth combing once the hair settles (Combing Hair 100 Times). Gently blot hair and allow the scalp skin to become completely clean and dry before applying leave-in care.
3. Post-Wash Scalp Nourishment Applying botanical oil infusions to the scalp skin and roots after washing. Apply a small amount of grapeseed-oil-based CYN-SILK No.02 Flourishing Elixir ($58) to the clean, dry scalp in the evening, massage gently with finger pads, and leave in overnight.
4. Morning Root Refresh Topical herbal washes featuring evergreen Ce Bai Ye (Platycladus orientalis) recorded in the Bencao Gangmu. Mist CYN-SILK No.01 Anchoring Mist ($42)—formulated with Platycladus orientalis leaf extract—evenly onto the morning scalp (avoiding the eyes).

The Book of Rites (Liji): Why Ancient Washing Was a Deliberate Sequence

In early Chinese texts, washing the hair (Mu, 沐) and bathing the body (Yu, 浴) had distinct names, vessels, and rhythms. The Liji (Book of Rites), a foundational ritual compendium describing Zhou and Han social norms, records these practices in vivid detail:

  • In the Yuzao (玉藻) chapter: The grooming of the junzi (cultivated scholar-official) is described as an orderly sequence—heating water, washing face and hair separately, using dedicated upper and lower drying cloths, and settling one's composure before stepping into public life (see The Scholar's Sanctuary).
  • In the Neize (内则) chapter: Household care is structured around a calm, sustainable rhythm—traditionally preparing warm water to wash the hair every three days and bathe the body every five. Cleanliness was understood not as a frantic 60-second scrub, but as an act of household order and respect.

The Science of Pan (潘): Grain Rinse Water and SPring-8 Imaging

Classical passages frequently mention washing the hair with Pan (潘)—the milky water left over from rinsing raw rice or millet. While contemporary beauty blogs often conflate all grain washes with long-fermented treatments, the classical term Pan specifically denotes the starchy rinse water itself.

Modern cosmetic science has investigated why grain rinse water leaves hair fibers feeling smoother:

Historically, when stronger degreasing was needed, grain washes were complemented by saponin-rich plant pods such as Zao Jia (Gleditsia sinensis, Chinese honey locust—whose thorn extract also appears in No.01 Anchoring Mist) and Wu Huan Zi (Sapindus mukorossi, soapberry), explored further in Before Modern Shampoo: The Saponin Plants of Chinese Cleansing.
