Severe Hair Loss — Which Shampoo Should I Use?
Most hair loss problems originate not from the hair strand itself, but from weak hair roots and insufficient blood circulation to the scalp. Choosing a targeted shampoo is essential.
Herbal shampoos with blood-circulation stimulants such as Capsicum Extract (Chili) or Moraceae Extract (Mahad) have been confirmed to nourish hair roots and reduce shedding — without relying on synthetic chemicals that may accumulate over time.
- SLS / SLES / DEA — Harsh surfactants commonly found in regular shampoos
- Silicone — Builds up, hard to rinse, weakens hair roots long-term
- Petroleum-derived mineral oils
Principle is a Thai herbal brand founded in 1998, and was the first in Thailand to receive the Green Label from the Thailand Environment Institute in 2001. All formulas are free from harsh surfactants, silicone, and petroleum oils.
