It is widely agreed by doctors and scalp specialists that biotin helps hair grow stronger, quicker, and thicker. The benefit of biotin for hair growth is that it causes stronger and healthier hair follicles to grow in. In turn, stronger hair is less likely to break – ultimately protecting your hair's length.
