//Yes, i believe a tight scalp has something to do with it, wether its the cause or a symptom of losing hair im not sure. Brown adipose tissue (BAT) is the layer of fat on the scalp that is transfered with a freshly transplanted hair. Its said to be the factor that enables the new hair to grow. Ive tried running the scriipt that newport mentions below. Havent come across any other frequencies to regenerate BAT.
