hair nails epidermal cells skin appendages terminal hair vellus hair keratin

TLDR Hair and nails are skin parts that develop early and serve protective and functional roles.

This chapter discussed the development and types of hair and the function of nails, both of which are modified epidermal cells classified as skin appendages. Human hair structures form between 9 weeks and 4 months after conception, starting from the head and progressing down the body. Hair is categorized into terminal and vellus types, with vellus hair transitioning to terminal hair during puberty. Nails, composed of tough keratin, grow from the epidermis of the toes and fingers, providing protection, aiding in grasping fine objects, and enhancing the strength of fingers and toes.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 1 year 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.

community Compressed part of research of theory of androgenic/anabolitic balance. AGA h-responders analytic. Theory of physio-metabolitic method of anti AGA treatment

in Research 865 upvotes 1 year ago

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.
