Glossary Nerves

bundles of fibers transmitting electrical signals in the body

Nerves are bundles of fibers that transmit electrical signals between the brain, spinal cord, and other parts of the body. They play a crucial role in controlling bodily functions, including movement, sensation, and reflexes. For example, sensory nerves carry information from the skin to the brain, while motor nerves send signals from the brain to muscles, enabling movement.

community I Guess balding is cured so should we close subreddit and move to hairstyling photos 😁 Botox-like nerve blocking reveals potential way to fully regenerate skin without scarring

6 months ago

Baldness is difficult to cure because current treatments like finasteride, dutasteride, and minoxidil only prevent hair shedding, and new developments are mostly ineffective. Botox shows potential in aiding skin regeneration and hair growth, but maintenance therapy with treatments like dutasteride and minoxidil may still be necessary.

community Weird response to microneedling

in Microneedling 40 upvotes 1 year ago

Microneedling can cause sneezing and eye tearing due to nerve stimulation, particularly near the temples and forehead. Some users find it lessens over time, while others prefer using finasteride and minoxidil for hair growth.

community Does anyone else sneeze or have their nose run when they microneedle their scalp?

in Microneedling 23 upvotes 2 years ago

Microneedling the scalp can cause sneezing, runny nose, and watery eyes due to nerve stimulation, histamine release, reflex actions, or sinus relief. Several users experience similar symptoms.
