I say do what you want. Dyeing your hair, including these DIY methods, come with risks. But the risks aren't too severe. For example, you may experience hair breakage at worse. The main factor to keep in mind is dyeing or lightening your hair over time. With time, this can cause your hair to become brittle and weak. That's why I suggest always going to a professional. I've been dyeing my hair regularly ever since I was 11 years old. I probably only DIY dyed my hair twice in that time. My hair is still long and healthy, even after bleaching it countless times. I still say it's because I always go to a pro. Even if you never dyed your hair, you should be using some of these treatment methods, such as hair masks and deep conditioners. As you would use a face mask and other treatments on your skin, these treatment methods ensure your hair is soft and healthy.
