This is important, guys. You have to know when to say enough is enough and just cut your hair off so it can grow healthier. I went from lower back length hair to just below the ear. Such a change is not necessary, you can just cut the damaged part. Then I had to cut out using oils on my hair since it was making it to greasy. And now that it's shoulder length I'm using some new things which are all below, check it out!
Lastly, hair is unique and different for all of us. You have to take some time and work with your hair figuring out what works for you and what doesn't. Understanding that healthy looking hair does not happen my mere luck but there are some factors behind it that we all must do if we want healthy looking hair. I hope this all helped and good luck!
