The Science of Hair Growth: Understanding Your Follicles
The Hair Growth Cycle Explained in Detail
Your scalp contains about 100,000 hair follicles that follow a precise growth schedule:
- Anagen Phase (Growth Stage)
- Lasts 2-7 years
- Hair grows about 1 cm per month
- 85-90% of your hair is in this phase
- Catagen Phase (Transition Stage)
- Lasts 2-3 weeks
- Hair stops growing and detaches from blood supply
- Affects 1% of hair at any time
- Telogen Phase (Resting Stage)
- Lasts 3 months
- Old hair falls out (50-100 strands daily is normal)
- 10-15% of hair is in this phase
When this cycle gets disrupted, you experience excessive shedding or thinning. Understanding your specific disruption point is key to effective treatment.

- Birth control adjustments
Nutritional Deficiencies
