Strong, healthy hair requires more than the right shampoo. Hydration and gut health play crucial roles in hair growth and quality.
Hydration and Hair
Hair is about 25% water. Dehydration affects:
- Hair shaft flexibility (dry, brittle hair)
- Scalp health
- Nutrient delivery to follicles
Signs of Dehydration Affecting Hair
- Dry, frizzy hair
- Lack of shine
- Increased breakage
- Dry, itchy scalp
Gut Health and Hair
Your gut affects hair through:
- Nutrient absorption
- Inflammation levels
- Hormone metabolism
- Immune function
Gut Issues That Affect Hair
- Celiac disease
- IBD
- SIBO
- Food intolerances
- Dysbiosis
Signs Gut Health Is Affecting Hair
- Hair loss with GI symptoms
- Nutrient deficiencies despite good diet
- Bloating, irregular bowels
- Autoimmune hair loss
Testing for Gut Issues
- Celiac panel (tTG-IgA, total IgA)
- Inflammatory markers (CRP, ESR)
- Nutrient levels (B12, iron, zinc, vitamin D)
- Complete blood count
Action Steps
1. Ensure adequate hydration 2. Address any GI symptoms 3. Test for celiac disease if hair loss is unexplained 4. Consider gut healing protocols if other signs present
