There are a lot of variables, from your lifestyle to weather conditions to hair. The Devachan salons may well have a controlled environment, air conditioning maintaining a fixed temperature and humidity level.

That makes me wonder. In her book she does not mention things like dew point, porosity or coarse/fine at all. Still she has amazing hair. The fact that she does not mention these makes me think she doesn't regard them as important? Or am I wrong there?
