hair follicle epithelial compartments dermal compartments growth factors cytokines hormones hair shaft curly hair hair bulb

TLDR Curly hair shape is determined by the hair bulb.

The document discussed the hair follicle as a unique, self-renewing organ composed of epithelial and dermal compartments that interact autonomously. It highlighted the follicle as a model of epithelial and mesenchymal interactions, with each compartment following a specific differentiation pathway regulated by growth factors, cytokines, and hormones. The shape of the hair shaft, including curly hair, was noted to be intrinsically programmed from the bulb.

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 10 months 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.

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 TWIST-1 and the cure: Is it really that easy?

in Research/Science 283 upvotes 3 years ago

TWIST-1 gene's role in hair loss and potential as a treatment target. Inhibiting TWIST-1 may prolong hair growth and reduce hair follicle sensitivity to DHT.

community Finasteride only reduces scalp DHT by ~40%. Why does it work?

in Finasteride/Dutasteride 37 upvotes 2 years ago

How Finasteride and Dutasteride help reduce hair loss by reducing the amount of DHT in scalp areas, as well as discussing factors such as sensitivity to DHT, 5α-reductase expression in different parts of the hair follicle, and scalp tension.

community Why is Minoxidil not enough for hair loss? (No fin)

in Minoxidil 55 upvotes 8 months ago

Minoxidil alone is often insufficient for treating hair loss because it doesn't address the DHT-related cause. Combining it with finasteride, a DHT blocker, is generally more effective.

community HairClone developing cell replacement treatments for Hair Loss

6 upvotes 6 years ago
