Hello, im a 18 years old male, I have a question about my hair. When I was about 13 years old I used hair gel everyday and also didn't shampoo at all, for almost a year. Today I have an extremely dry and unhealthy hair which I hate, only now I realize this might be because of what I did back than. I wanted to ask if I might caused a permanent damage to my hair or is it treatable, and if so. What should I do? Thanks in advance and sorry about my english its not my native language. Also I might have posted this question but I just can not find it. So sorry if this is the second time I post this.
