This study found that UV radiation exposure increased protein elution and altered protein characteristics in hair fibers, suggesting environmental factors impact hair shaft proteins.
The user started using ketoconazole shampoo and whey protein shakes and noticed increased hair shedding, seeking advice on whether these could be the cause. Another user shared their experience with hair loss after starting protein shakes and mentioned using finasteride, which eventually improved their hair condition.
A user is experiencing genetic hair loss and is using spironolactone and minoxidil without success. They are considering switching to vegan protein powder due to digestive issues and are concerned if it will worsen hair loss.
Whey protein may slightly increase hair loss in men with androgenetic alopecia (AGA) due to elevated IGF-1 and testosterone levels, but the effect is minimal compared to treatments like finasteride and dutasteride. Many users argue that whey protein's impact on hair loss is negligible and that maintaining a healthy lifestyle is more important.
Whey protein isolate may worsen androgenetic alopecia (AGA) due to its potential to increase DHT levels, but finasteride use has helped maintain hair. Some users suggest avoiding protein supplements due to possible contaminants and additives that could affect hair health.
Hair loss may be influenced by mechanical tension and inflammation, with the hi-c5 protein amplifying androgen effects, leading to follicle miniaturization. Treatments like finasteride, minoxidil, and scalp massages are suggested to manage hair loss.
