In this research, experienced clinicians noted inconsistency in the reproducibility of the commonly used Hamilton-Ludwig scales for assessing pattern hair loss severity in photographic assessments, leading to the proposal of a new 5-point scale for staging female hair loss.

This study, examining perceptible hairdensity changes in androgenetic alopecia patients, found that dermatologists could accurately detect hair loss at a lower threshold than previously noted, specifically at a 22.66% relative density difference, challenging assumptions about their predictive accuracy based solely on clinical examination.

This study found that Korean men with androgenetic alopecia have lower hairdensity and a higher proportion of single-hair units compared to normal adult males.

This exploratory pilot study reported that using a 2% Oleosome-FGF-2 fusion extract scalp serum twice daily for 84 days in women with telogen effluvium and brittle hair improved hairdensity, anagen/telogen ratio, hair shaft thickness, and scalp hydration compared to a placebo.
The conversation discusses differences in hair shaft diameter and density between thinning and denser areas on the scalp. Treatments mentioned include Minoxidil, finasteride, and dutasteride.
The user is experiencing severe shedding and progressive hairdensity loss after a successful hair transplant, despite using finasteride, minoxidil, microneedling, and scalp treatments. Suggestions include trying stronger treatments like oral dutasteride, topical RU58841, and higher doses of oral minoxidil.
A 20-year-old experiencing hair loss since age 16 is using finasteride and minoxidil and is considering future hair transplants. Discussions include the potential for multiple transplants, the use of body hair for coverage, and the importance of treatments like dutasteride and scalp micropigmentation for maintaining hairdensity.
The user is unhappy with the results of their second hair transplant, feeling that grafts were wasted on an already transplanted hairline instead of increasing mid-scalpdensity. They regret stopping medications like Dutasteride, Minoxidil, and RU58841, which led to significant hair loss, and plan to restart them.
Using PP405 and Clascoterone after a hair transplant may not cause issues if the transplant didn't achieve native density, but could lead to competition for blood supply if it did. Some users suggest waiting for these drugs to be available, as they might not significantly impact blood supply or regrowth.
