March 2024 in “Asian journal of medical sciences” In this study, researchers found that a ring block technique was the most accepted anesthesia modality for platelet-rich plasma injections in hair loss treatment, with the least post-procedural pain compared to other methods like vibration anesthesia and nerve blocks.
January 2021 in “Journal of clinical & experimental dermatology research” This study found that a new propylene glycol-free 5% minoxidil lotion demonstrated good clinical efficacy and very good cosmetic acceptability and tolerability after six months of use in patients with androgenetic alopecia, showing results comparable to traditional formulations containing propylene glycol.
April 2024 in “Asian Journal of Medical Sciences” This study found that ring block anesthesia was the most acceptable method for reducing pain during platelet-rich plasma injections for hair loss.
January 2021 in “Medical research archives” In this study, researchers examined a new propylene glycol-free 5% minoxidil lotion for 6 months among individuals with androgenic alopecia and found it demonstrated good clinical efficacy, with 74% showing a positive response, and very high cosmetic acceptability and tolerability, comparable to traditional formulations.
In this study, centralised measurements provided more consistent and accurate results for assessing hair loss in mild-to-moderate alopecia areata, reducing error compared to local ratings.
