research Follicle-innervating Aδ-low threshold mechanoreceptors organize through a population-dependent mechanism
Mouse touch-sensitive nerve cells adjust their connections based on competition with other similar cells.
research The Functional Organization of Cutaneous Low-Threshold Mechanosensory Neurons
Different hair follicles in the skin are innervated by unique combinations of mechanosensory neurons, crucial for touch sensation.
research Robust coupling between the C‐tactile afferent and the hair follicle in humans
C-tactile nerves are sensitive to hair movement.
research Mechanical stimulation of human hair follicle outer root sheath cultures activates adjacent sensory neurons
Touching hair can activate nearby nerve cells through signals from the hair's outer layer.
research eLife assessment: Touch receptor end-organ innervation and function require sensory neuron expression of the transcription factor Meis2
Meis2 is essential for touch sensation and proper nerve connection to touch receptors in certain skin areas of mice.

Switching from finasteride to dutasteride and back to finasteride led to gynecomastia and fatigue, likely due to hormonal imbalances. Suggested treatments include Tamoxifen, Raloxifene, or low-dose Anastrozole, with a recommendation to test testosterone and estradiol levels.
community Sugar and Hair loss connections
High sugar diets may worsen hair loss by increasing 5α-reductase activity and androgen levels, especially in women with PCOS. A low sugar diet might reduce scalp DHT levels, similar to finasteride, but genetics also significantly influence hair loss.
community Looking for suggestions on vitamins
A user is seeking affordable hair vitamins without biotin, already taking zinc and D3+K2, and has been dealing with chronic telogen effluvium since 2013. They previously used Nutrafol Vegan but found it too expensive.
community Finasteride only reduces scalp DHT by ~40%. Why does it work?
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 Study: There is 70x Higher Unconjugated DHT in Feces Compared To Blood Levels in Young Adults - Gut Microbiota Manages DHT Recycling and Metabolism
Gut microbiota significantly influences androgen metabolism, impacting hair loss treatments like finasteride. Probiotics, dietary changes, and fecal microbiota transplants may help manage DHT levels and improve hair health.
