This paper presents a culturally informed protocol designed to improve the collection of hair samples from African Americans for cortisol measurement, illustrating its application with community-based study data.
This study concluded that human sweat contributes to haircortisol concentrations, potentially affecting interpretations of chronic stress and OSA-related stress levels, with CPAP reducing psychological but not physiological stress after 3 months.
This study examines various methodological factors affecting haircortisol concentration analysis, finding inconsistent results on the impact of factors like resuspension solution, hair weight, extraction duration, and hair-cutting method.
The user discusses their hair loss experience, exploring various hypotheses including thyroid levels, vitamin D, DHEA, nutritional deficiency, diabetes, seborrheic dermatitis, lack of nutrition to hair follicles, chronic inflammation, female pattern hair loss causes, cortisol, and prolactin levels. They are currently using finasteride, beta-sitosterol, and have tried topical dutasteride and microneedling therapy.
Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.
Creatine does not increase DHT levels or cause hair loss. Personal experiences vary, but scientific evidence shows no link between creatine and hair loss.
Creatine does not cause or worsen hair loss, despite some anecdotal reports of hair thinning. The discussion emphasizes that these reports are not supported by scientific evidence.
Clascoterone (Breezula) shows promising hair growth results, but skepticism remains due to past disappointments with new treatments. It may be a good alternative for those who can't tolerate finasteride or dutasteride, and can potentially be combined with them and minoxidil for better results.
