I am only four weeks post and I have a ton of new growth! I have been having this problem(well, not really a problem) since I started taking Biotin. This time around, I switched salons just to see if the stylist was under processing my hair. It's definitely not underprocessed. I mixed some oils together and I put some Neutrogena Triple Moisture Leave In on my scalp. That has helped soften the NG and calm the itching/soreness. It's a blessing and a curse.
