Glossary Inflammatory Pathways

molecular signals triggering the body's response to harmful stimuli

Inflammatory pathways, also known as inflammatory signaling pathways, are a series of molecular signals and reactions that the body uses to respond to harmful stimuli, such as pathogens, damaged cells, or irritants. These pathways involve various cells and proteins, including cytokines and chemokines, which work together to initiate and regulate inflammation, ultimately aiming to protect and heal the body. Understanding these pathways is crucial for developing treatments for conditions like alopecia, where inflammation can play a significant role in hair loss.

research Major Differences in Expression of Inflammatory Pathways in Skin from Different Body Sites of Healthy Individuals

18 citations , May 2019 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study observed significant differences in immune cell infiltration and gene expression across different skin sites, with the back displaying higher tolerance-promoting immune mechanisms, which may enhance epicutaneous immunotherapy outcomes.

research Particulate matter exposure induces maternal scalp hair loss after birth in C57/B6 mouse via alteration of inflammatory and apoptotic pathways

May 2026 in “Frontiers in Endocrinology”

In a mouse model, this study found that exposure to PM2.5 leads to significant postpartum hair loss, apparent via morphological changes and elevated markers of inflammation, apoptosis, and fibrosis, potentially exacerbated by changes in hormone receptors and stem cell populations.

research Dracorhodin Perchlorate Regulates the Expression of Inflammatory Cytokines through the TLR4 Pathway and Improves Skin Wound Healing in Diabetic Rats

4 citations , April 2022 in “Evidence-based Complementary and Alternative Medicine”

This study found that dracorhodin perchlorate improved wound healing in diabetic rats by regulating the TLR4 pathway and related inflammatory factors.

research miR‐200a‐3p in Human Umbilical Cord Mesenchymal Stem Cell‐Derived Exosomes Attenuates UVB‐Induced Skin Inflammatory Response and Oxidative Stress via Keap1‐Nrf2 Pathway

January 2025 in “Stem Cells International”

This study found that exosomes from human umbilical cord mesenchymal stem cells reduced oxidative stress and inflammation in UVB-induced skin injury in cell and mouse models, suggesting their potential for treating UV-damaged skin by influencing Nrf2 and NF-κB pathways.

research 705 Particulate matter induces inflammatory response in human outer root sheath cells via oxidative stress-dependent MAPK and JAK-STAT signaling pathways

July 2022 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study suggests that particulate matter can induce inflammation in human outer root sheath cells, potentially affecting hair growth, through oxidative stress-dependent MAPK and JAK-STAT signaling pathways.

community Any chances of my hairloss being inflammatory?

5 upvotes 2 weeks ago

A 20-year-old male has been experiencing hair loss since age 15-16 and is using oral minoxidil, dutasteride, and ketoconazole shampoo, with previous use of oral finasteride and topical minoxidil. He has stabilized hair loss but seeks to rule out inflammatory or immune-related causes, considering a scalp biopsy, and is supplementing with vitamin D3, B12, and iron.

community I had claude create a protocol only using fda approved drugs.

4 upvotes 8 months ago

A new hair loss protocol using FDA-approved topical treatments targets eight pathways, potentially improving results by 60-75% compared to the standard 40-50% from oral minoxidil and finasteride. The protocol includes minoxidil, finasteride, tacrolimus, cetirizine, bimatoprost, lithium gluconate, losartan, melatonin, NAC, caffeine, and tretinoin, with a monthly cost of $35-50 in Mexico and $80-150 in the US.

community Reducing Fibrosis in Hair Loss: Topical Pirfenidone

59 upvotes 6 months ago

Topical pirfenidone is highlighted as an effective anti-inflammatory and anti-fibrotic treatment for hair loss, particularly in addressing perifollicular fibrosis, which may enhance the effectiveness of standard treatments like finasteride and minoxidil. The user also uses calcipotriol, MCT oil, ciclopirox shampoo, and benzoyl peroxide shampoo as part of their regimen.

community High cholesterol causes hair loss?

16 upvotes 2 years ago

High cholesterol may lead to hair loss by causing cicatricial alopecia, an inflammatory disorder. Treatments discussed include cholesterol medication and statins.

community Why Fin/Dut Isn't Working for You GPR133: a new hairloss mechanism + Steroid Hair Loss Deep Dive

6 upvotes 2 months ago

Hair loss may be linked to the GPR133 receptor, independent of the androgen receptor pathway. Treatments like finasteride, dutasteride, minoxidil, RU58841, and KX-826 show varying results, with hair loss persisting due to high testosterone and GPR133's role.

learn capsicum

Is capsicum safe for sensitive scalps or inflammatory hair loss? Capsicum may irritate sensitive scalps and worsen inflammatory hair loss.

learn Cetirizine

What makes cetirizine a unique anti-inflammatory option for your scalp? Laboratory work reports that cetirizine lowers PGD2 and other inflammatory mediators, which is why researchers have proposed it for the scalp. There is no approved topical product and the clinical evidence is a few small trials in pattern hair loss (none in inflammatory scalp disease), so scalp use is off-label and experimental.
