From what I’ve seen, transplanted hairs remain thick and healthy for life - at least until the point of which the sides and back miniaturise with old age 70+ .
I doubt that the likes of Tsuji would be balancing billions of dollars of research towards a ‘cure’ on a hope that his transplanted cell hairs will just miniaturise.
Also there is no explanation for the ‘programming’ of follicles. If the scalp tension theory was the true cause of Androgenetic Alopecia then a healthy follicle from the back transplanted into a blood deprived area should begin to die straight away .
well when you cause deep wounds wouldnt that cause vegf to upregulate and cause new blood flow to the transplanted cells until that blood flow is affected much further later on in life?
