Hello ! Thank you for your question. In my opinion you have nothing to worry about it. The headache you have is caused by the contracted muscles of the scalp due to hair traction by the band in this case. It may be also aggravated by a wrong position of your head ( during staying or writing, working at the computer), from psychological stress, etc. Dizziness is another feature of this kind of headache ( Tension type Headache). Nothing is going to happen to your brain if you continue holding the band. Your brain is well protected! We have seen in patient who underwent brain surgery , that the bands very straight to the head can cause damage of skin in the pressure point, but it is not your case. Your band is not so tight, also you don t have it on during night. You may just make pauses ( remove it) remove it during the day , so your muscles get a little relaxed. You will get pain relief. Hope to have been helpful to you. Thank you for using HCM! Best wishes, Dr. Abaz
