Here's why:
* Hair growth is determined by genetics and hormones. Combing simply arranges the existing hair strands.
* Combing can improve the appearance of hair. It can make it look smoother and shinier, but it doesn't actually affect the growth process.
* Regular combing can help prevent tangles and breakage. This can help keep hair healthy and looking its best.
So, while combing is good for hair health and appearance, it doesn't have any magical power to make hair grow longer.
