Does Heat Speed Up Hair Growth?
While heat can stimulate blood flow to the scalp and improve the overall health of hair follicles, it does not directly speed up hair growth. Hair growth is primarily governed by genetics and hormone levels, and cannot be accelerated by external factors such as heat. However, using heat styling tools and treatments excessively can damage the hair and lead to breakage and hair loss, which can make it appear as though the hair is not growing as quickly as it could be.
