I shampooed my hair and noticed my hair was tangled-under further inspection I noticed it was matted (imagine a dredloc or hair glued together) I went to a hairstylist & she said she can untangle it but I will lose a lot of hair-which I died. My hair is MUCH thinner & some sections of my hair is super short. Was there so much trauma to my hair that it won't regrow & if not, what are some things I can do to expedite my hair regrowth? I currently take biotin pills (5,000 mg)
