Hair loss (alopecia) affects millions worldwide. While shedding 50-100 hairs daily is normal, excessive loss can lead to thinning or baldness. This comprehensive guide covers everything you need to know about hair loss, with expert-backed information on causes, treatments, and prevention strategies.
Understanding Hair Growth Cycles
Your hair grows in three phases:
- Anagen (Growth Phase)
- Lasts 2-7 years
- 90% of hair is in this phase
- Catagen (Transition Phase)
- Lasts 2-4 weeks
- Hair stops growing
- Telogen (Resting Phase)
- Lasts 3-4 months
- Hair sheds naturally
Disruptions in this cycle cause excessive hair loss.
