I went to the salon and had highlights done then a so called botox hair treatment. Says it's a healthy protein for your hair no to straighten it or anything. This was done and left on my hair for more then 45 minutes. Closer to and hour and a half then washed out and blown out . It was silker ashes smoother but right after and ever since I have been feeling a hot sensation and a little pressure on the back of my scalp and head and starting to see my hair falling out for nothing. What can be happening?
