On average, hair grows about half an inch (1.25 cm) per month. So, it typically takes around 2 months for hair to grow one inch. However, this rate can vary depending on factors like:
- Genetics
- Age
- Health and nutrition
- Hair care practices
- Hormonal changes
If you want to promote healthy hair growth, maintaining a balanced diet, staying hydrated, and minimizing damage from heat or chemicals can help.
