every day, without checking
the hairgoals hygrometer
If you don't want to check every day, keep a hairgoals hygrometer in your room. It's particularly useful if you work from home, so you can optimise your hair care around the humidity you're actually sitting in — not the weather outside.
- Under 40% — dry room. Damp hair only, seal heavily.
- 45–70% — the glycerin sweet spot. Use freely.
- Over 80% — go light. Protect against over-moisture.
Guidance is based on live humidity and dew point data for your location. Every head of hair is different — start light and build up. For all hair types, type 4 approved.
