research Genome-wide association meta-analysis of individuals of European ancestry identifies new loci explaining a substantial fraction of hair color variation and heritability

94 citations , April 2018 in “Nature Genetics”

This study identified more than 100 genetic loci associated with hair color variation in Europeans, explaining a significant portion of the trait's heritability and advancing understanding of hair pigmentation.

research Cutaneous malignant melanoma incidences analyzed worldwide by skin type over advancing age of males and females: Evidence estrogen and androgenic hair are risk factors

3 citations , December 2016 in “Journal of epidemiological research”

In this study, only European-ancestry females showed a linear increase in cutaneous malignant melanoma risk with age, potentially due to the loss of HPV-infected androgenic follicles after menopause.

research Variation in human hair ultrastructure among three biogeographic populations

28 citations , November 2018 in “Journal of structural biology”

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

research Admixture in Latin America: Geographic Structure, Phenotypic Diversity and Self-Perception of Ancestry Based on 7,342 Individuals

340 citations , September 2014 in “PLOS Genetics”

This study found that while genetic ancestry affects physical appearance traits in Latin American populations, it accounts for only a modest portion of the observed variation.

research High-coverage genome of the Tyrolean Iceman reveals unusually high Anatolian farmer ancestry

31 citations , August 2023 in “Cell Genomics”

This study produced a high-coverage genome of the Tyrolean Iceman, revealing no Steppe-related ancestry but significant Anatolian-farmer-related ancestry, and found genetic markers associated with darker skin, male-pattern baldness, type 2 diabetes, and obesity, aligning with observations of his mummified body.

community Day 1 vs 6 months vs 1 year vs 2 years. Finasteride, minoxidil and derma rolling.

2749 upvotes 1 year ago

A user documented their two-year hair regrowth journey using finasteride, minoxidil, and derma rolling, showing significant improvement. They switched from topical to oral minoxidil after the first year, experiencing some shedding and minor bloating.

community Went to a new barber who casually said “well you don’t need to worry about balding anytime soon.” Feeling grateful for dutasteride right now :)

in Finasteride/Dutasteride 39 upvotes 4 years ago

A user's experience with taking finasteride and dutasteride to address hair loss, and the proactive approach they took to maintain their hair. They discussed using these medications every day and transitioning between them.

community Why do we have head hair in first place if we evolved to start losing it in some cases as soon as puberty hits

140 upvotes 11 months ago

Hair loss is influenced by genetics and sensitivity to hormones like DHT. Treatments like Minoxidil and finasteride are commonly used, and baldness persists as it doesn't affect reproductive success.

community Why do we get bald from evolutionary perspective

in Chat 213 upvotes 1 year ago

Baldness is not an evolutionary disadvantage because it occurs after reproductive age. Treatments like Minoxidil and Finasteride are used for androgenetic alopecia but don't address the root cause.

community My Theory Of Androgenic Alopecia

16 upvotes 10 months ago

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
