Here's why:
* Hair growth is determined by genetics and internal factors: Hair growth is primarily influenced by factors like genetics, hormones, nutrition, and overall health.
* Braiding protects hair from damage: Braiding can help protect hair from breakage and split ends, which can make it *appear* longer as it's not breaking off.
* Braids can help retain moisture: Braids can help retain moisture, which can contribute to healthier hair, but it doesn't affect the rate of growth.
The bottom line: Braiding hair is a great styling technique that can help keep your hair healthy and manageable, but it won't speed up the growth process.
