Glossary Cholesterol Homeostasis

balance of cholesterol levels in the body

Cholesterol homeostasis refers to the balance the body maintains to regulate cholesterol levels. This involves processes like cholesterol synthesis in the liver, dietary absorption, and removal from the body. Proper cholesterol homeostasis is crucial for cell membrane integrity and hormone production, while imbalances can lead to health issues like cardiovascular disease.

community Bile Acid-Mediated DHT Dysregulation Hypothesis

in Research/Science 13 upvotes 1 year ago

Elevated bile acids can inhibit the enzyme AKR1C2, leading to increased DHT levels, which may accelerate hair loss in those predisposed to androgenetic alopecia. Treatments mentioned include topical minoxidil and finasteride.

community if Post Finasteride Syndrome is real. Why is it only the negative effects and not positive have log term effect?

in Finasteride/Dutasteride 63 upvotes 5 months ago

Finasteride is used for hair loss, with mixed reports of no side effects and claims of long-term negative effects known as Post Finasteride Syndrome (PFS). The conversation debates the existence and causes of PFS, with differing opinions on whether it is psychological or real.

community 1.25mg oral minoxidil-3 month progress

in Progress Pictures 633 upvotes 1 year ago

A 44-year-old man experienced significant hair regrowth after switching from topical to 1.25mg oral minoxidil and 0.5mg daily finasteride, with no side effects. He noticed hair thickening after two months and credits the oral form's effectiveness.

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

in Research 830 upvotes 2 years 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 High cholesterol causes hair loss?

16 upvotes 2 years ago
