After a month of taking iron, my iron level normalized and my hair has continued to thicken up in much of the top (to where the barber thinned a section for the first time since ~2006).  Not really the left corner and not the crown or back, though all that looks stable now and very little hair comes out in the shower. I do not have celiac. Invasive examination so far hasn’t found anything that would affect hair or absorption.

How long should I wait to see if any regrowth in the problem areas happens?

When I had hair, I always had a high hairline. Should I put my hairline high as it was when I had hair?

There are two ways to determine where the midline hairline belongs. (1) one finger width above the highest crease of the furrowed brow and (2) balance the distance between the nose and chin to the grove above the nose to the hairline (that is what Michelangelo did). When designing a hairline, I always use these rules and if the forehead has always been high, then these rules allow you not to have a huge forehead for the rest of your life. Attractive people are always in a balance with their facial features.

From what I’ve read, the underlying theory for advanced classes not responding as well is due to scalp fibrosis, however that is understood to be reduced by an increase of bloodflow and microneedling. If scalp fibrosis is the culprit as to why NW6~+ don’t respond as well then hypothetically in time, enough microneedling and enough of an increase in bloodflow should result in an increase in hair growth right? I’m certainly getting vellus growth in my hairline at the sides and towards the middle front.

That being said, after almost an entire year on my regimen, I’m having what seems to be my first shed and it’s almost exclusively my intermediate hairs that have grown from vellus in my frontal mid scalp region. What has me excited is that I’m not getting any bulbs pushed up like when you lose hair so it seems like this is an expected healthy shed. I’m excited to see what replaces them in the next 3-6 months!

When an area of the head has been bald for quite a while, it loses its blood flow as the body regulates blood flow where it is needed. Normally, hair is a high metabolically active organ, so it commands blood flow. When the hair dies off with apoptosis (hair cell death as we believe it does), then the body figures that the blood flow can be better used elsewhere. This means that the skin of a older bald area, becomes atrophic and looses all of its support infrastructure for the hair which includes blood vessels and fat.

Lifting weights supposedly makes you release more testosterone, which means more dht, which means more miniaturization? Is this true to any extent?

No, working out does not increase hair loss. It might help by reducing stress.

I’m showing clear signs of MPB and have started Fin, Min and Biotin. I’d be happy with maintaining my current hair and will only hope to see some thicker hairs and maybe revitalize some dormant follicles along the way.

But I did notice just this year that the thinning was happening very quickly. I have pictures from just 5 months ago where I have much thicker hair front to back. I have short hair too, so it’s noticeable now. Around the same time earlier this year I went to an urgent care facility when I was feeling extremely strange with my heart. They ran a few tests and said I was OK. Since then, almost everyday I have spurts of faintness, lightheadedness, dizziness, etc. Especially if I have caffeine, after I exercise or getting up and down a lot. I’m going to the doctor this week as I had written off all the symptoms since I showed normal test results when I was concerned last time, but now want a bit more of an answer and treatment.

So, I’m just wondering if abnormal (low) blood flow to my head may have accelerated hair thinning and loss.

The scalp has an extremely high blood flow because actively growing hair has a high demand for oxygen and other nutrients.  As hair start to miniaturize or fall out, the demand for blood flow decreases and your body is smart enough to redirect that blood flow elsewhere.  When you look a men with long standing balding, their scalp is very thin (no fat or hair follicles) so the blood flow is significantly reduced to this scalp.  The good news is that when it is transplanted, this process runs in reverse, building back blood flow to nourish the newly transplanted hairs.  The other parts of your questions need to be addressed with your doctor.

If this was true, maybe he would have no donor hair left if is was done by FUE unless he was one of the rare men with extremely high donor density. May be he actually got 7000 hairs not grafts. 

This is an excellent result from using finasteride and minoxidil for 7 months.  It is not unusual for the crown to respond to these two medications.
