androgenic alopecia probiotic mixture telogen hairs anagen hairs Lactobacillus terminal follicles miniaturization AGA probiotics

TLDR Probiotics help reduce hair loss and increase hair growth in people with androgenic alopecia.

This randomized clinical trial evaluated the effect of a probiotic mixture on androgenic alopecia (AGA) in 136 participants (62 men and 74 women) over 16 weeks. Of the 115 who completed the study, those in the probiotic group showed a significant reduction in telogen hairs and an increase in anagen hairs, while the placebo group experienced a decrease in hair thickness. Younger participants in the probiotic group also saw reductions in telogen hair density and increases in hair length. The probiotic group had a higher abundance of Lactobacillus and no adverse effects, with a 90% adherence rate. The study concludes that the probiotic mixture helps maintain terminal follicles and prevents their miniaturization, a key feature of AGA.

research Concentrated Growth Factor from Autologous Platelet Promotes Hair Growth in Androgenetic Alopecia

1 citations, January 2019 in “Journal of Biomedical Science and Engineering”

The study demonstrated that concentrated growth factor (CGF) from autologous platelets significantly promoted hair regrowth and improved hair density and appearance in 15 patients with androgenetic alopecia (AGA) over 12 weeks. Hair density increased from 40.8 ± 17.4/cm² to 50.0 ± 20.9/cm², and the terminal to vellus hair ratio improved from 47.1% ± 17.3% to 80.2% ± 43.6%. Most patients reported satisfaction with the treatment, and no adverse effects were observed, although some experienced slight pain during injections. The study concluded that CGF treatments were effective and safe for promoting hair growth in AGA patients, but noted the need for further research with larger sample sizes and long-term follow-up.
