Hair Growth Calculator: Track Your Progress

Hair growth is a natural biological process that varies from person to person. On average, human hair grows about 1.25 centimeters (0.5 inches) per month, or about 15 centimeters (6 inches) per year. However, this rate can be influenced by various factors including genetics, age, health, nutrition, and hair care practices.

The Hair Growth Cycle

Your hair grows through a cycle consisting of three phases:

• Anagen (Growth) Phase: This active growth phase lasts 2-7 years for scalp hair. The longer this phase, the longer your hair can grow.
• Catagen (Transition) Phase: A short transitional phase lasting about 2-3 weeks, where hair growth stops.
• Telogen (Resting) Phase: A resting phase lasting 2-4 months before the hair falls out and the cycle begins again.

Average Hair Growth Rates

• Slow Growth: Approximately 0.8 cm (1/3 inch) per month
• Average Growth: Approximately 1.25 cm (1/2 inch) per month
• Fast Growth: Approximately 1.7 cm (2/3 inch) per month

Factors Affecting Hair Growth

• Genetics: Your genes largely determine your hair's growth rate, texture, and thickness
• Age: Hair growth typically slows down as you age
• Hormones: Hormonal changes can affect hair growth, especially during pregnancy, menopause, or thyroid issues
• Nutrition: Deficiencies in protein, iron, zinc, and vitamins can impair hair growth
• Health Conditions: Certain medical conditions can affect hair growth
• Medications: Some medications may either slow or accelerate hair growth
• Hair Care Practices: Heat styling, chemical treatments, and rough handling can lead to breakage
• Scalp Health: A healthy scalp environment promotes better hair growth

Tips for Healthy Hair Growth
