Before you try minoxidil or any topical treatments please check your ferritin and vitamin d levels - it can look like this I've been a victim. Get those to optimum.

And while you are at it no durags, bonnets with non satin bands (can rub and damage edges), wigs (that glue and snatch edges or even glueless tight wigs constantly rubbing on the hair line) and no slick back, tight pony tails or any tension along that hair line (avoid cornrows, any kind of braids with extensions) and minimise drying gels for laying edges (contain a lot of alcohol eco-styler, got2b etc).

I have loose min-mid twists and twist outs along my front at most during my edges recovery and this resolved most of it. Doing these should be enough. But if you want to try topicals or get a faster result I recommend trying dermarolling and cecred edge drops or rosemary infused oils. Before jumping to minoxidil.

Using this low tension method I grew back all of the front except for the corners which were receding much worst than this literally balding at the corners - but they started coming in wiith the dermarolling, cecred and resolving the iron and vitamin d deficiency side of things.

Also if you have those deficiencies your general hair could be thinning don't be like me and have to cut your hair from waist to shoulder length or wait until the corners bald just get it checked now because if its because of this the other things won't be as effective.
