Did you mean Sebaceous Gland Hyperplasia?

Glossary Sebaceous Gland Hyperplasia

enlarged oil glands causing small, yellowish facial bumps

Sebaceous Gland Hyperplasia is a condition where the sebaceous glands, which are responsible for producing oil (sebum) to lubricate the skin, become enlarged. This often results in small, yellowish bumps on the skin, typically on the face. While generally harmless, it can be mistaken for other skin conditions, and its appearance may be of cosmetic concern.

Setipiprant may help with hair maintenance but is not a guaranteed solution for everyone. Other treatments like minoxidil, finasteride, and topical spironolactone are discussed, with varying opinions on their effectiveness.

community Physio-metabolic method of treating androgenic alopecia. Cold receptors. The relationship between DHT, cold receptors, minoxidil and antiandrogens.

2 upvotes 1 year ago

A method for treating androgenic alopecia using minoxidil, antiandrogens, exercise, and cold exposure to promote hair growth. Environmental factors and lifestyle changes, like diet and exercise, can improve treatment effectiveness.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 2 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

community How is dht not beneficial to you?

in Finasteride/Dutasteride 111 upvotes 7 months ago

DHT is important for sexual function and mood, but finasteride and dutasteride can reduce DHT, causing side effects like reduced libido and erectile dysfunction. These treatments are effective for hair loss, but their impact on DHT leads to debate.

community Topical Finasteride Doesn't Directly Reduce 5ar Enzyme on Scalp

in Finasteride/Dutasteride 72 upvotes 3 years ago

Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.
