Did Chemical Relaxers Permanently Damage My Hair?

I am a 25 year old African American male and I have been relaxing my hair since I was 15 now my hair is very thin and I know its because of the relaxers because baldness does not run in my family, I have been wearing my hair natural for the last 4 months and i’ve bought Rogaine and have been using it for the last three days do you think it will work for me in any way or have I permantly damaged my hair? If there is anything I can do and what products do you suggest? Because i’m so afraid of being bald or keeping my hair this thin.

Thank you for reading
God Bless

Although chemical relaxers can cause damage to hair, you need to be examined by a properly trained physician to make sure you do not have another reason for your hair loss. With your long term use of chemicals and heat, there is a high probability that you have damaged your hair. A miniaturization study would definitely help to understand the role of MPB in your hair. Without knowing the true cause of your hair loss it is hard for me to recommend a treatment.
