I am 26, I am have been losing alot of my hair for about five years, lots of thinning and resending hair line, and for about 4 months its been extremely itchy, when I went to get my hair cut the stylist recommended nexus shampoo and conditioner so that’s what i been using but I don’t know if that’s the cause for the itching because I tried going but to my old shampoo and everything but its not working. any suggestions. when I sweat or get my hair wet and let it relax without drying it itches worse. any help with hair loss and itching. thanks.
