Part 3
Rye Flour
Saponins, rye proteins, B vitamins — plus the recipe and the honest 4–6 week adjustment phase.
Why it works
Rye flour has been used as a hair cleanser in Eastern Europe for centuries. Today we can name the active parts.
- Saponins — plant compounds that foam gently on contact with water and cleanse at a scalp-friendly pH. Onlom et al., Int J Cosmet Sci 2014 (PMID: 24117781) documented antifungal activity against Malassezia furfur.
- Rye proteins — amino acids bind to the hair shaft, smooth the cuticle and reduce breakage, much like a commercial protein treatment.
- B vitamins (B1, B2, B3, B5, B6, B9) — support cell renewal and a calm, comfortable scalp.
- Starch and enzymes — absorb excess sebum and gently exfoliate, keeping follicles clear without stripping.
The adjustment phase
Weeks 1–2: hair may feel greasy or waxy while the sebaceous glands are still in shampoo mode. Weeks 3–4: oil production slows. Weeks 5–6: hair feels lighter and balanced, and wash intervals naturally stretch.
