I'm 22 years old and have always had really good hair but I am having hair loss around my hairline and have this yellowish spots around where I am losing it, my scalp has become very itchy and dry. What can I do to help this, I'm freaking out kinda cause it has just came out of no where. I have used nixion shampoo for like 2 years just because of it being a good shampoo not because of thin hair. Is regenepure a good way to go for me? What can I do to grow back what has been lost? And when I feel around my scalp it almost feels shaved underneath my hair. Please give me some advice!
