Thais whether male or female have beautiful hair because their water is natural unlike the chemically treated Newater which is extremely caustic.
Besides chlorine and chloramine, sulphuric acid, hydrochloric acid and hydrogen peroxides ... etc are used to purify sewage water for drinking. Imaging what all these chemicals can do to your hair, skin and your organs. CECA, foreign workers and tourists are stealing our reservoir water hence the need to replenish it with shit water.
