if your hair has never grown past a certain point there is a possibility that is your terminal length (genetically predetermined length your hair cannot exceed). though there are many other factors as to why it wouldn't be growing any longer, one being, yes stress! stress can completely stunt the growth of your hair so I do suggest trying to relax and de-stress because your hair will barely grow otherwise. another factor is diet. your diet needs to have plenty of protein since your hair is made out of a protein called keratin. also lots of fruits and veggies as well as water. now taking a biotin supplement (vit b6) can maximize your hair growth. (im taking 2000-3000 mcg's a day) mcg stand for micrograms! it is water soluble so I suggest drinking lots of water with it for optimal results and to prevent it from causing acne.
