Abstract in Plain English
Dehydration affects every organ—including the scalp. A 2025 study in International Journal of Trichology measured barrier function and hydration status in volunteers with chronic dry scalp.
Key Findings
- Low hydration elevated transepidermal water loss and irritation.
- Adequate water intake improved pH stability and oil distribution.
- Moisture-rich shampoos reduced micro-flaking and itch scores by 25%.
- Proper hydration enhanced nutrient delivery to follicles.
Why It Matters
Hydration is a simple but often overlooked pillar of hair wellness. Balancing internal and external moisture preserves scalp integrity and comfort.
Study Limitations
The study did not measure internal hydration levels, only skin-surface metrics.
