Shedding from Highlighting Hair Months Ago

Black female 36: Hair is thinning from shedding due to highlights put in months ago. What can be done to help this?

Don’t assume that your thinning is from the highlighting. It sounds doubtful. I can not blindly stab at an answer to your questions without access to you, get your correct history, examine you, etc. You should see a dermatologist if the hair does not regrow. Not much I can do online at this point.
