TLDR Tianzhu white yak hair varies in structure and density between fuzz and coarse hair.

The study examined the histological and ultrastructural characteristics of Tianzhu white yak hair using optical and scanning electron microscopy. It found that heterotypical and fuzz hair from different body parts were similar in structure, while coarse hair fibers showed variations, especially in the medullated fibers. The scale layer structure and density varied among different fiber types, with significant differences (P<0.01) between fuzz and coarse hair. Additionally, there were notable differences (P<0.05) in the scale height and thickness between fuzz and coarse hair.

community microneedle, any long term users damage?

in Microneedling 35 upvotes 5 months ago

Microneedling is effective for hair growth, especially when combined with finasteride and minoxidil, but concerns exist about potential long-term skin damage. Users report increased collagen and elastin deposition, but the long-term effects on the scalp remain uncertain.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 3 months ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
