A blend of nettle tea and natural gels, plus essential oils to be used for hair growth and health.  Can be left on for a few hours as a masque, or simply massaged into hair right before washing.
 
It only need be applied on the actual scalp - unless your hair is damaged, in which case, it can be applied to all your hair.  But for hair growth / fine hair, just apply to the scalp (about 20ml per application) and then massage in for 5 mins with your fingers.  
 
This product is best stored in the fridge if you are not using regularly to extend the shelf life.
