The hair growth cycle is made up of four different stages:
If the hair follicles don't get sufficient nutrients regularly they can experience a shortening of the growth stage. This is where the super star Rosemary comes into play... Rosemary is capable of improving blood flow to hair follicles, thus preventing them from being deprived of the nutrients they require for growth. This can actively lengthen the Anagen stage, allowing your hair strands to grow longer.
A 2015 research study carried out on Alopecia sufferers, also proved that Rosemary can effectively heal nerve endings in the hair follicles, promoting hair restoration.
