TLDR Male and female mice have different lipid compositions in their skin during hair growth cycles.

The study examines the lipid composition of mouse epidermis across different stages of the hair growth cycle, highlighting differences between sexes. On the 4th day of the cycle, male epidermis shows lower total lipid content but higher phospholipid levels compared to the 12th and 22nd days. In contrast, female epidermis consistently has twice the total lipid and half the phospholipid content of males at similar stages. Both sexes exhibit a similar pattern in the total lipid-phospholipid ratio throughout the cycle. Additionally, 4th day male epidermis is notable for its high cholesterol content, low triglycerides, and significant lipid material eluted with cholesterol esters.

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

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.

Increased Malassezia and Cutibacterium in the scalp microbiome are linked to higher sebum production and inflammation in androgenetic alopecia (AGA). Treatments include ciclopirox shampoo, benzoyl peroxide shampoo, clobetasol propionate, calcipotriol, minoxidil, finasteride, and dutasteride.

Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

A 27-year-old man saw significant hair regrowth after starting a regimen in January that included topical minoxidil with finasteride, vitamins D and B12, fish oil, zinc with magnesium, quitting smoking, and intermittent fasting. People commented on the effectiveness of minoxidil in Southern populations and asked about the details and timeline of his treatment.
